windowing_taAll Signals Are the Sum of Sines. When looking at real-world signals, you usually view them as a price changing over time. This is referred to as the time domain. Fourier’s theorem states that any waveform in the time domain can be represented by the weighted sum of sines and cosines. For example, take two sine waves, where one is three times as fast as the other–or the frequency is 1/3 the first signal. When you add them, you can see you get a different signal.
Although performing an FFT on a signal can provide great insight, it is important to know the limitations of the FFT and how to improve the signal clarity using windowing. When you use the FFT to measure the frequency component of a signal, you are basing the analysis on a finite set of data. The actual FFT transform assumes that it is a finite data set, a continuous spectrum that is one period of a periodic signal. For the FFT, both the time domain and the frequency domain are circular topologies, so the two endpoints of the time waveform are interpreted as though they were connected together. When the measured signal is periodic and an integer number of periods fill the acquisition time interval, the FFT turns out fine as it matches this assumption. However, many times, the measured signal isn’t an integer number of periods. Therefore, the finiteness of the measured signal may result in a truncated waveform with different characteristics from the original continuous-time signal, and the finiteness can introduce sharp transition changes into the measured signal. The sharp transitions are discontinuities.
When the number of periods in the acquisition is not an integer, the endpoints are discontinuous. These artificial discontinuities show up in the FFT as high-frequency components not present in the original signal. These frequencies can be much higher than the Nyquist frequency and are aliased between 0 and half of your sampling rate. The spectrum you get by using a FFT, therefore, is not the actual spectrum of the original signal, but a smeared version. It appears as if energy at one frequency leaks into other frequencies. This phenomenon is known as spectral leakage, which causes the fine spectral lines to spread into wider signals.
You can minimize the effects of performing an FFT over a noninteger number of cycles by using a technique called windowing. Windowing reduces the amplitude of the discontinuities at the boundaries of each finite sequence acquired by the digitizer. Windowing consists of multiplying the time record by a finite-length window with an amplitude that varies smoothly and gradually toward zero at the edges. This makes the endpoints of the waveform meet and, therefore, results in a continuous waveform without sharp transitions. This technique is also referred to as applying a window.
Here is a windowing_ta library with J.F Ehlers Windowing functions proposed on Sep, 2021.

ADX Screener// Identify potential trend reversals using ADX on up to 40 crypto assets.
// ADX shows the strength of a trend, not the direction.
// By monitoring the difference of ADX values between candles, you can potentially identify reversals before they happen.
// A strong trend has a 14 period ADX slope increasing .5 or more from the prior candle.
// At a minimum, a weak trend has a 14 period ADX slope of +.25 or less, and strictly it would be decreasing.
// This indicator prints one row for each asset with three columns for ADX differences one candle back each.
// The asset name is colored green or red dependent on whether +DI > -DI or not.
The market was in a down trend (-DI > +DI).
A bullish wave moved price up to EMA 8 resistance with strong ADX momentum (ADX diff of prior candle >= 0.5).
A Spinning Top showed that the trend was losing momentum (ADX diff lower than previous candle, showed the bullish wave losing momentum).
A Morning Star bearish reversal pattern draws resistance at the high of the pattern. (ADX Bullish momentum exhausted).
Symbol: -DI > +DI
2: Strong momentum
1: Losing momentum (spinning top)
0: Trend reversal (bearish engulfing pattern)
Cavuca Technical AnalysisScript created by Cavuca-Trader for technical analysis of various assets. It is based on analysis of moving averages and also on Elliot wave movements, signaling entries and exits through its own coloration.
Mode of Viewing the indicator: Moving averages are used to assist in the movement of the asset's trend by observing its slope. The indicator recognizes market movements and detects the tops and bottoms of the movement by creating horizontal lines. When candles break these lines they gain color according to the trend of the movement.
Notes in the author's language:
Script criado por Cavuca-Trader para análise técnica de diversos ativos . Basea-se em análise de médias móveis e também em movimentos das Ondas de Elliot , sinalizando entradas e saídas através de coloração própria.
Modo de Visualizar o indicador: As médias móveis servem para auxiliar na movimentação de tendência do ativo observando a sua inclinação. O indicador reconhece os movimentos do mercado e detecta os topos e fundos do movimento criando linhas horizontais. Quando os candles rompem essas linhas ganham a coloração de acordo com a tendência do movimento.
40 crypto screener [LUPOWN]// ENGLISH
This indicator shows two tables, with 10 assets each, they can be currencies, stocks or cryptos, the columns can be changed to the information you want to see, among the options are price or change (change in percentage of the candle in the temporality where you are seeing it), TL are buy or sell signals according to the Latin trading strategy (Squeeze momentum combined with ADX) buy if the momentum changes to range or rise and the ADX has a negative slope, sell if the momentum changes to range or fall and The ADX has a negative slope, the signals are not 100% effective, you must support it with price action and market speculation, directionality in the momentum, slope of the ADX, if there is divergence in the momoentum squeeze, lux something and cipher use an indicator of Lazy bear, lux something signals when two wave trends cross and the cipher signals when the wave trend crosses above or below the 0 point.
You can choose between seeing one or two tables, this so that it can be seen on small screens, there is also the option to hide the tables and show the label, which is also an alternative to see it on small screens
i got the main idea from @QuantNomad
//SPANISH
Este indicador muestra dos tablas, con 10 activos cada una, pueden ser divisas, acciones o cryptos, las columnas se pueden cambiar a la información que quieras ver, entre las opciones están precio o cambio (cambio en porcentaje de la vela en la temporalidad donde lo estes viendo), TL son señales de compra o venta según estrategia de trading latino (Squeeze momentum combinado con ADX) compra si el momentum cambia a rango o subida y el ADX tiene pendiente negativa, venta si el momentum cambia a rango o caída y el ADX tiene pendiente negativa, las señales no son 100% efectivas debes apoyarla con la acción del precio y especulación del mercado, direccionalidad en el momentum, pendiente del ADX, si hay divergencia en el squeeze momoentum, lux algo y cipher utilizan un indicador de Lazy bear, lux algo da señal cuando dos wave trend se cruzan y el cipher da señal cuando el wave trend cruza por encima o debajo del punto 0.
Puedes elegir entre ver una o dos tablas, esto para que se pueda ver en pantallas pequeñas, también esta la opción de ocultar las tablas y mostrar el label, que también es una alternativa para verlo en pantallas pequeñas
La idea principal la tome de @QuantNomad
LA_Crpyto_Pirate Modifie VuManChu B Script with Scalping FiltersI added the following filters for entry signals to the VuManChu B with divergences for use as a scalping indicator. You will need to load the 50 EMA and this indicator to trade this per the rules below
The rules for trading this are as follows; You can only take a long or short entry when all of these requirements match
The wave cross is under the zero line (long) or over the zero line (short)
The money flow indicator is green (long) or red (short)
The closing price is above the 200 EMA (long) or below the 200 EMA (short)
price has pulled back to the 50 EMA
Here are the filters I employed in the script to help you trade this
Zero Line Filter: Only signal longs under the zero line and shorts over the zero line will fire off a signal
Money Flow Indicator Filter: Only signal longs when money flow is green and only shorts when money flow is red
200 MA filter: Only longs when price is closing above the 200 EMA and only shorts when price is closing below the 200 EMA
When you get an alert, simply check to see that price has pulled back to the 50 EMA before entering. Place long and short orders when the indicator signals and you confirm price has pulled back to the 50 ema before entering the long or short. Set your Stop Loss above or below the pervious pullback and set a reward ratio of your choice. Good luck!
Auto TrendLines [HeWhoMustNotBeNamed]I started off with the intention of creating script to identify Wolfe wave projection. But, soon ran into problem with loops. Realized drawing wedge is more difficult than drawing converging triangle. Hence, took a step back and started working on wedges and triangle identification. Ended up with a messy output which looked like this.
Had to take another step back and hence decided to make Trendlines detection script and here we are :)
⬜ Process
▶ Scan pivots which are in trend. This means, series of pivot Highs or pivot lows either in ascending order or descending order.
▶ Draw trend line between each of the pivots in the trend series. For example, if there are 5 pivot high uptrend pivots, draw mXn lines between each of these points.
▶ Select the trend line which is more accurate or stronger. Accuracy is measured by number of candles/wicks touching the line and number of candles which fall outside the line. Stronger trendlines will touch more candles and pivots with less overflow.
▶ Remove all lines except the most accurate one for each direction.
At any point of time, you will see upto 4 trend lines in this script.
▶ Trendline joining pivot highs in uptrending condition
▶ Trendline joining pivot lows in uptrending condition
▶ Trendline joining pivot highs in downtrending condition
▶ Trendline joining pivot lows in downtrending conditions
The older line will remain until the new one comes through of same type. Hence, you will still be able to see uptrending high and low trend lines for downtrending instruments which are created way back!! Also, new trendlines replace old ones only if they are more stronger (connect to more pivots with less overflow)
⬜ Settings
Settings are simple.
User can select preferred Zigzag Length and Search Depth. Higher numbers for these two parameters will present longer term trends whereas lower numbers will display shorter ones.
Trend Lines controlls will allow users to enable/disable specific type of trend line, set color and line style to it.
⬜ Few Examples
▶ Uptrending Market : NASDAQ:NDX
▶ Downtrending Market : NYSE:BABA
▶ Ranging Market : NYSE:PLTR
Realtime 5D Profile [LucF]█ OVERVIEW
This indicator displays a realtime profile that can be configured to visualize five dimensions: volume, price, time, activity and age. For each price level in a bar or timeframe, you can display total or delta volume or ticks. The tick count measures activity on a level. The thickness of each level's line indicates its age, which helps you identify the most recent levels.
█ WARNING
The indicator only works in real time. Contrary to TradingView's line of volume profile indicators , it does not show anything on historical bars or closed markets, and it cannot display volume information if none exists for the data feed the chart is using. A realtime indicator such as this one only displays information accumulated while it is running on a chart. The information it calculates cannot be saved on charts, nor can it be recalculated from historical bars. If you refresh the chart, or the script must re-execute for some reason, as when you change inputs, the accumulated information will be lost.
Because "Realtime 5D Profile" requires time to accumulate information on the chart, it will be most useful to traders working on small timeframes who trade only one instrument and do not frequently change their chart's symbol or timeframe. Traders working on higher timeframes or constantly changing charts will be better served by TradingView's volume profiles. Before using this indicator, please see the "Limitations" section further down for other important information.
█ HOW TO USE IT
Load the indicator on an active chart (see here if you don't know how).
The default configuration displays:
• A double-sided volume profile showing at what price levels activity has occurred.
• The left side shows "down" volume, the right side shows "up" volume.
• The value corresponding to each level is displayed.
• The width of lines reflects their relative value.
• The thickness of lines reflects their age. Four thicknesses are used, with the thicker lines being the most recent.
• The total value of down/up values for the profile appears at the top.
To understand how to use profiles in your trading, please research the subject. Searches on "volume profile" or "market profile" will yield many useful results. I provide you with tools — I do not teach trading. To understand more about this indicator, read on. If you choose not to do so, please don't ask me to answer questions that are already answered here, nor to make videos; I don't.
█ CONCEPTS
Delta calculations
Volume is slotted in up or down slots depending on whether the price of each new chart update is higher or lower than the previous update's price. When price does not move between chart updates, the last known direction is used. In a perfect world, Pine scripts would have access to bid and ask levels, as this would allow us to know for sure if market orders are being filled on upticks (at the ask) or downticks (at the bid). Comparing the price of successive chart updates provides the most precise way to calculate volume delta on TradingView, but it is still a compromise. Order books are in constant movement; in some cases, order cancellations can cause sudden movements of both the bid and ask levels such that the next chart update can occur on an uptick at a lower price than the previous one (or vice versa). While this update's volume should be slotted in the up slot because a buy market order was filled, it will erroneously be slotted in the down slot because the price of the chart's update is lower than that of the previous one. Luckily, these conditions are relatively rare, so they should not adversely affect calculations.
Levels
A profile is a tool that displays information organized by price levels. You can select the maximum quantity of levels this indicator displays by using the script's "Levels" input. If the profile's height is small enough for level increments to be less than the symbol's tick size, a smaller quantity of levels is used until the profile's height grows sufficiently to allow your specified quantity of levels to be displayed. The exact position of levels is not tethered to the symbol's tick increments. Activity for one level is that which happens on either side of the level, halfway between its higher or lower levels. The lowest/highest levels in the profile thus appear higher/lower than the profile's low/high limits, which are determined by the lowest/highest points reached by price during the profile's life.
Level Values and Length
The profile's vertical structure is dynamic. As the profile's height changes with the price range, it is rebalanced and the price points of its levels may be recalculated. When this happens, past updates will be redistributed among the new profile's levels, and the level values may thus change. The new levels where updates are slotted will of course always be near past ones, but keep this fluidity in mind when watching level values evolve.
The profile's horizontal structure is also dynamic. The maximum length of level lines is controlled by the "Maximum line length" input value. This maximum length is always used for the largest level value in the profile, and the length of other levels is determined by their value relative to that maximum.
Updates vs Ticks
Strictly speaking, a tick is the record of a transaction between two parties. On TradingView, these are detected on seconds charts. On other charts, ticks are aggregated to form a chart update . I use the broader "update" term when it names both events. Note that, confusingly, tick is also used to name an instrument's minimal price increment.
Volume Quality
If you use volume, it's important to understand its nature and quality, as it varies with sectors and instruments. My Volume X-ray indicator is one way you can appraise the quality of an instrument's intraday volume.
█ FEATURES
Double-Sided Profiles
When you choose one of the first two configuration selections in the "Configuration" field's dropdown menu, you are asking the indicator to display a double-sided profile, i.e., where the down values appear on the left and the up ones on the right. In this mode, the formatting options in the top section of inputs apply to both sides of the profile.
Single-Sided Profiles
The six other selections down the "Configuration" field's dropdown menu select single-sided profiles, where one side aggregates the up/down values for either volume or ticks. In this mode, the formatting options in the top section of inputs apply to the left profile. The ones in the following "Right format" section apply to the right profile.
Calculation Mode
The "Calculation" input field allows the selection of one of two modes which applies to single-sided profiles only. Values can represent the simple total of volume or ticks at each level, or their delta. The mode has no effect when a double-sided profile is used because then, the total is represented by the sum of the left and right sides. Note that when totals are selected, all levels appear in the up color.
Age
The age of each level is always displayed as one of four line thicknesses. Thicker lines are used for the youngest levels. The age of levels is determined by averaging the times of the updates composing that level. When viewing double-sided profiles, the age of each side is calculated independently, which entails you can have a down level on the left side of the profile appear thinner than its corresponding up side level line on the right side because the updates composing the up side are more recent. When calculating the age of single-sided profiles, the age of the up/down values aggregated to calculate the side are averaged. Since they may be different, the averaged level ages will not be as responsive as when using a double-sided profile configuration, where the age of levels on each side is calculated independently and follows price action more closely. Moreover, when displaying two single-sided profiles (volume on one side and ticks on the other), the age of both sides will match because they are calculated from the same realtime updates.
Profile Resets
The profile can reset on timeframes or trend changes. The usual timeframe selections are available, including the chart's, in which case the profile will reset on each new chart bar. One of two trend detection logics can be used: Supertrend or the one used by LazyBear in his Weis Wave indicator . Settings for the trend logics are in the bottommost section of the inputs, where you can also control the display of trend changes and states. Note that the "Timeframe" field's setting also applies to the trend detection mechanism. Whatever the timeframe used for trend detection, its logic will not repaint.
Format
Formatting a profile for charts is often a challenge for traders, and this one is no exception. Varying zoom factors on your chart and the frequency of profile resets will require different profile formats. You can achieve a reasonable variety of effects by playing with the following input fields:
• "Resets on" controls how frequently new profiles are drawn. Spacing out profiles between bars can help make them more usable.
• "Levels" determines the maximum quantity of levels displayed.
• "Offset" allows you to shift the profile horizontally.
• "Profile size" affects the global size of the profile.
• Another "Size" field provides control over the size of the totals displayed above the profile.
• "Maximum line length" controls how far away from the center of the bar the lines will stretch left and right.
Colors
The color and brightness of levels and totals always allows you to determine the winning side between up and down values. On double-sided profiles, each side is always of one color, since the left side is down values and the right side, up values. However, the losing side is colored with half its brightness, so the emphasis is put on the winning side. When there is no winner, the toned-down version of each color is used for both sides. Single-sided profiles use the up and down colors in full brightness on the same side. Which one is used reflects the winning side.
Candles
The indicator can color candle bodies and borders independently. If you choose to do so, you may want to disable the chart's bars by using the eye icon near the symbol's name.
Tooltips
A tooltip showing the value of each level is available. If they do not appear when hovering over levels, select the indicator by clicking on its chart name. This should get the tooltips working.
Data Window
As usual, I provide key values in the Data Window, so you can track them. If you compare total realtime volumes for the profile and the built-in "Volume" indicator, you may see variations at some points. They are due to the different mechanisms running each program. In my experience, the values from the built-in don't always update as often as those of the profile, but they eventually catch up.
█ LIMITATIONS
• The levels do not appear exactly at the position they are calculated. They are positioned slightly lower than their actual price levels.
• Drawing a 20-level double-sided profile with totals requires 42 labels. The script will only display the last 500 labels,
so the number of levels you choose affects how many past profiles will remain visible.
• The script is quite taxing, which will sometimes make the chart's tab less responsive.
• When you first load the indicator on a chart, it will begin calculating from that moment; it will not take into account prior chart activity.
• If you let the script run long enough when using profile reset criteria that make profiles last for a long time, the script will eventually run out of memory,
as it will be tracking unmanageable amounts of chart updates. I don't know the exact quantity of updates that will cause this,
but the script can handle upwards of 60K updates per profile, which should last 1D except on the most active markets. You can follow the number of updates in the Data Window.
• The indicator's nature makes it more useful at very small timeframes, typically in the sub 15min realm.
• The Weis Wave trend detection used here has nothing to do with how David Weis detects trend changes.
LazyBear's version was a port of a port, so we are a few generations removed from the Weis technique, which uses reversals by a price unit.
I believe the version used here is useful nonetheless because it complements Supertrend rather well.
█ NOTES
The aggregated view that volume and tick profiles calculate for traders is a good example of one of the most useful things software can do for traders: look at things from a methodical, mathematical perspective, and present results in a meaningful way. Profiles are powerful because, if the volume data they use is of good enough quality, they tell us what levels are important for traders, regardless of the nature or rationality of the methods traders have used to determine those levels. Profiles don't care whether traders use the news, fundamentals, Fib numbers, pivots, or the phases of the moon to find "their" levels. They don't attempt to forecast or explain markets. They show us real stuff containing zero uncertainty, i.e., what HAS happened. I like this.
The indicator's "VPAA" chart name represents four of the five dimensions the indicator displays: volume, price, activity and age. The time dimension is implied by the fact it's a profile — and I couldn't find a proper place for a "T" in there )
I have not included alerts in the script. I may do so in the future.
For the moment, I have no plans to write a profile indicator that works on historical bars. TradingView's volume profiles already do that, and they run much faster than Pine versions could, so I don't see the point in spending efforts on a poor ersatz.
For Pine Coders
• The script uses labels that draw varying quantities of characters to break the limitation constraining other Pine plots/lines to bar boundaries.
• The code's structure was optimized for performance. When it was feasible, global arrays, "input" and other variables were used from functions,
sacrificing function readability and portability for speed. Code was also repeated in some places, to avoid the overhead of frequent function calls in high-traffic areas.
• I wrote my script using the revised recommendations in the Style Guide from the Pine v5 User Manual.
█ THANKS
• To Duyck for his function that sorts an array while keeping it in synch with another array.
The `sortTwoArrays()` function in my script is derived from the Pine Wizard 's code.
• To the one and only Maestro, RicardoSantos , the creative volcano who worked hard to write a function to produce fixed-width, figure space-padded numeric values.
A change in design made the function unnecessary in this script, but I am grateful to you nonetheless.
• To midtownskr8guy , another Pine Wizard who is also a wizard with colors. I use the colors from his Pine Color Magic and Chart Theme Simulator constantly.
• Finally, thanks to users of my earlier "Delta Volume" scripts. Comments and discussions with them encouraged me to persist in figuring out how to achieve what this indicator does.
TASC 2021.11 MADH Moving Average Difference, Hann█ OVERVIEW
Presented here is code for the "Moving Average Difference, Hann" indicator originally conceived by John Ehlers. The code is also published in the November 2021 issue of Trader's Tips by Technical Analysis of Stocks & Commodities (TASC) magazine.
█ CONCEPTS
By employing a Hann windowed finite impulse response filter (FIR), John Ehlers has enhanced the Moving Average Difference (MAD) to provide an oscillator with exceptional smoothness.
Of notable mention, the wave form of MADH resembles Ehlers' "Reverse EMA" Indicator, formerly revealed in the September 2017 issue of TASC. Many variations of the "Reverse EMA" were published in TradingView's Public Library.
█ FEATURES
Three values in the script's "Settings/Inputs" provide control over the oscillators behavior:
• The price source
• A "Short Length" with a default of 8, to manage the lower band edge of the oscillator
• The "Dominant Cycle", originally set at 27, which appears to be a placeholder for an adaptive control mechanism
Two coloring options are provided for the line's fill:
• "ZeroCross", the default, uses the line's position above/below the zero level. This is the mode used in the top version of MADH on this chart.
• "Momentum" uses the line's up/down state, as shown in the bottom version of the indicator on the chart.
█ NOTES
Calculations
The source price is used in two independent Hann windowed FIR filters having two different periods (lengths) of historical observation for calculation, one being a "Short Length" and the other termed "Dominant Cycle". These are then passed to a "rate of change" calculation and then returned by the reusable function. The secret sauce is that a "windowed Hann FIR filter" is superior tp a generic SMA filter, and that ultimately reveals Ehlers' clever enhancement. We'll have to wait and see what ingenuities Ehlers has next to unleash. Stay tuned...
The `madh()` function code was optimized for computational efficiency in Pine, differing visibly from Ehlers' original formula, but yielding the same results as Ehlers' version.
Background
This indicator has a sibling indicator discussed in the "The MAD Indicator, Enhanced" article by Ehlers. MADH is an evolutionary update from the prior MAD indicator code published in the October 2021 issue of TASC.

█ OVERVIEW
This library holds technical analysis functions calculating values for which no Pine built-in exists.
Look first. Then leap.
█ FUNCTIONS
cagr(entryTime, entryPrice, exitTime, exitPrice)
It calculates the "Compound Annual Growth Rate" between two points in time. The CAGR is a notional, annualized growth rate that assumes all profits are reinvested. It only takes into account the prices of the two end points — not drawdowns, so it does not calculate risk. It can be used as a yardstick to compare the performance of two instruments. Because it annualizes values, the function requires a minimum of one day between the two end points (annualizing returns over smaller periods of times doesn't produce very meaningful figures).
Parameters:
entryTime : The starting timestamp.
entryPrice : The starting point's price.
exitTime : The ending timestamp.
exitPrice : The ending point's price.
Returns: CAGR in % (50 is 50%). Returns `na` if there is not >=1D between `entryTime` and `exitTime`, or until the two time points have not been reached by the script.
█ v2, Mar. 8, 2022

MACD PlusMoving Average Convergence Divergence – MACD
The MACD is an extremely popular indicator used in technical analysis. It can be used to identify aspects of a security's overall trend. Most notably these aspects are momentum, as well as trend direction and duration. What makes the MACD so informative is that it is actually the combination of two different types of indicators. First, the MACD employs two Moving Averages of varying lengths (which are lagging indicators) to identify trend direction and duration. Then, it takes the difference in values between those two Moving Averages (MACD Line) and an EMA of those Moving Averages (Signal Line) and plots that difference between the two lines as a histogram which oscillates above and below a center Zero Line. The histogram is used as a good indication of a security's momentum.
Added Color Plots to Settings Pane.
Switched MTF Logic to turn ON/OFF automatically w/ TradingView's Built in Feature.
Added Ability to Turn ON/OFF Show MacD & Signal Line.
Added Ability to Turn ON/OFF Show Histogram.
Added Ability to Change MACD Line Colors Based on Trend.
Added Ability to Highlight Price Bars Based on Trend.
Added Alerts to Settings Pane.
Customized Alerts to Show Symbol, TimeFrame, Closing Price, MACD Crosses Up & MACD Crosses Down Signals in Alert.
Alerts are Pre-Set to only Alert on Bar Close.
Added ability to show Dots when MACD Crosses.
Added Ability to Change Plot Widths in Settings Pane.
Added in Alert Feature where Cross Up if above 0 or cross down if below 0 (OFF By Default).
Squeeze Pro
Traditionally, John Carter's version uses 20 period SMAs as the basis lines on both the BB and the KC.
In this version, I've given the freedom to change this and try out different types of moving averages.
The original squeeze indicator had only one Squeeze setting, though this new one has three.
The gray dot Squeeze, call it a "low squeeze" or an "early squeeze" - this is the easiest Squeeze to form based on its settings.
The orange dot Squeeze is the original from the first Squeeze indicator.
And finally, the yellow dot squeeze, call it a "high squeeze" or "power squeeze" - is the most difficult to form and suggests price is under extreme levels of compression.
Colored Directional Movement Index (CDMI) , a custom interpretation of J. Welles Wilder’s Directional Movement Index (DMI), where :
DMI is a collection of three separate indicators ( ADX , +DI , -DI ) combined into one and measures the trend’s strength as well as its direction
CDMI is a custom interpretation of DMI which presents ( ADX , +DI , -DI ) with a color scale - representing the trend’s strength, color density - representing momentum/slope of the trend’s strength, and triangle up/down shapes - representing the trend’s direction. CDMI provides all the information in a single line with colored triangle shapes plotted on the bottom. DMI can provide quality information and even trading signals but it is not an easy indicator to master, whereus CDMI simplifies its usage. The CDMI adds additional insight of verifying/confirming the trend as well as its strength
Label :
Displaying the trend strength and direction
Displaying adx and di+/di- values
Displaying adx's momentum (growing or falling)
Where tooltip label describes "howto read colored dmi line"
Ability to display historical values of DMI readings displayed in the label.
Added "Expert Trend Locator - XTL"
The XTL was developed by Tom Joseph (in his book Applying Technical Analysis ) to identify major trends, similar to Elliott Wave 3 type swings.
Blue bars are bullish and indicate a potential upwards impulse.
Red bars are bearish and indicate a potential downwards impulse.
White bars indicate no trend is detected at the moment.
Added "Williams Vix Fix" signal. The Vix is one of the most reliable indicators in history for finding market bottoms. The Williams Vix Fix is simply a code from Larry Williams creating almost identical results for creating the same ability the Vix has to all assets.
The VIX has always been much better at signaling bottoms than tops. Simple reason is when market falls retail traders panic and increase volatility , and professionals come in and capitalize on the situation. At market tops there is no one panicking... just liquidity drying up.
The FE green triangles are "Filtered Entries"

Pivot Target (5m Futures)I am new to both Futures Trading and Pivots. Looking for shorter-term profitable opportunities, I have investigated the use of pivots from a higher timeframe. All the work of this script is performed using two lines. It calculates the pivot from the previous 2-hour bar and draws this pivot line on the 5-minute timeframe. Many many times, the price will reach back to this pivot point - sometimes fairly quickly within the same horizontal pivot line and sometimes farther out (4-hours to 6-hours, or within the next few days). Price tends to reach the level around ninety percent of the time, making for plenty of short-term trading opportunities.
I get the best results when I see the price rise or fall from the pivot, along with a second indicator indicating a possible reversal (my favorite is Divergence for Many Indicators v4 by LonesomeTheBlue . Who knew divergence (both regular and hidden) was so common and useful for finding probable reversals? If I find the price above or below the pivot line with a second signal, I'll place a buy or sell within that same 2-hour window the price tends to return back to the higher timeframe pivot for a nice profit very quickly. Other times it does take a little longer to return with only a small percentage of time not returning within a reasonable amount of time, or very unusually, not at all. The image above shows a number of profitable trading opportunities using a combination of the Pivot Target and LonesomeTheBlue's Divergence for Many Indicators v4. You can further limit risk by only taking trades that are in the same direction of the overall trend, possibly confirmed on a higher timeframe.
This script will only be visible on the 5-minute timeframe the way it is written right now. I wouldn't suggest shorter or longer timeframes unless some editing is done by you. It doesn't seem to work as well with stocks, but is best on Futures due to the wave-like natures of the futures market. Trade safe, trade with the trend, use stops and limits appropriately and stay safe.
[RedK] Stepped Moving Average Channel (SMAC)The Stepping Moving Average Channel (SMAC) is not an indicator - It is more of a trading tool that was put together to enable a trader to take advantage of relatively fast price moves with quick incremental gain - maybe by exploiting opportunities to trade basic options (Calls, Puts) or to help with in/out-type swing trades. This is more a price-level visualization tool so please use it with this in mind, and not as a trading tool by itself.
While it looks very similar to a Donchian channel, SMAC plots a stepping channel of the moving average of the high & low prices (channel borders) - with an envelope that is at a user-specified % distance from the channel borders.
This setup, when combined with other Moving Averages and lower indicators, may make it easier for a trader to prepare for a trade with clear entry and exit price levels being planned upfront.
For example, a trader wants to capture 2% of the next move, will set the envelope to 2% and have clearer view of entry/exit price levels for such a scenario. once the trader receives confirmation (from other indicators or charts) that the price is heading in the way expected, the SMAC may make it simpler and quicker to estimate (and visualize) the entry/exit price levels and track the movement.
* The stepping feature helps remove price noise and the auto-stepping feature is designed to "snap to" those mental price levels that trader gravitate towards.
* The moving average type I used here is the Compound Ratio MA (CoRA_Wave) .
* This MA type was selected because it has a very high responsiveness and good smoothness, and tracks the price values very closely.
* The MA type can be replaced within the code with any other MA as preferred.
The auto-stepping feature:
----------------------------------
User can override the auto-stepping by entering a manual step value
when the auto-stepping is active, it will attempt to pick the best step size based on the underlying price range and the timeframe selected.
The step selection may not be ideal in some combination of value / TF - i will continue to improve these combinations
Stepping can also be completely disabled - this bring SMAC back to a regular (though highly responsive) Hi/Lo MA channel with envelope
The Excel table snippet in the chart above shows the various step value / TF combinations.
Also the stepping values can be further customized by changing the appropriate part in the script.
Other features:
--------------------
* Rounding Options: The stepping calculations uses one of 2 selectable methods:
1 -- regular rounding (uses the round() function): which rounds the price up & down depending on where it is compared to the half-step value
example: a value of 17 with a step of 10 will be rounded to 20. a value of 13 in that case will be rounded to 10
2 -- Whole Step (uses the int() function): this will only consider whole/fully completed steps - if the average (hi or low) does not explicitly exceed the next step level, we will not get that next value.
example: both values of 17 and 13 with a step of 10 will be rounded to 10.
* The "Quick Table":
The Quick Table shows on the top-left - and can be disabled in the script settings - It shows the currently selected stepping mode and value - since the auto-step changes dynamically with the selected chart timeframe, this makes it easier for the trader to view the active "configuration"
overall, i hope some traders find this quick utility useful - if not to use, maybe to inspire other ideas
- please feel free to use or customize in any way you need. Feel free to share feedback and observations.
[pp] Signal GeneratorResearch and Development Tool.
For anyone who is familiar with working with digital signals (audio/electrical engineers) you might appreciate this Signal Generator.
You can select and vary 4 different types of signals.
Logistic Map
If you're not familiar with the logistic map, then go watch a youtube video. By default the equation is meant to represent chaos and is a good alternative for random number generation.
Random
This uses the built-in random number generator. I'm not sure if it's better to use this or the logmap default settings. Either way, you have a choice.
Unit Impulse
Good for creating a transient impulse.
Step Impulse
Similar to the unit impulse. Except constant and not a transient.
Synthesizer
It comes with 4 wave functions (Sine, Triangle, Square, Saw) that can be combined for additive synthesis. Each wave function contains its own respective phase and amplitude control.
Credits
Many of these functions were taken from www.pinecoders.com with the exception of the logistic map. I simply aggregated them all into this toolkit for ease of use.
How to use
This is not a trading indicator. This is meant to be used for research and development. You could use it to test strategies, by generating white noise with the logmap and creating trading signals. Or you could use it for teaching and learning. Using the constant data as a dependable, repeatable resource.
Trading ABCHello Traders,
For a few months I have been getting requests from my followers about ABC pattern and finally I decided to make this indicator.
How it works?
- It creates Trend Cloud using Simple and Exponential moving averages with the lenghts 50, 100, 150, 200, 20, 40 by default and checks the trend. you can change the lengths as you wish
- It also creates ZigZag using the ZigZag Period in the options.
- Using last 2 zigzag waves it checks if there is suitable ABC pattern according the Trend, the Min/Max Fibonacci levels and Error Rate
- Then it check if the price bounces after this ABC pattern
- And if all these conditions met then it plot triangle
- If there are multiple bouncing then you can see multiple triangles
You can change/set;
- Zigzag Period
- Fibonacci Max level
- Fibonacci Min Level
- Error Rate
- The Lengths that are used for Moving Averages
- Keeping old ABC lines/labels
- Show Zigzag and min/max Fibonacci levels
- Show Trend Cloud
- and colors
if you don't want to see old ABC lines/labels you can disable it:
if you don't want to see Trend Cloud you can disable it:
Zigzag and Fibonacci levels:
P.S. if you have new ideas to improve this indicator then let me know please. We together can do this life easier!
Enjoy!
Zigzag SARThis is another ZigZag script. But the difference between this and other ZigZag indicators on TV is that here we find highs and lows based on Parabolic SAR.
It repaints?
YES.
On last line of ZigZag you get repainting, because the highs and lows get confirmation only if direction (SAR dots) changes.
This shouldn't be used to forecast highs and lows directly anyway, it's just a visual guide for past highs and lows.
I'm using it to spot harmonic patterns and Wolfe waves more easily. The plan is to draw these automatically in the future, but my skills at Pinescript are limited at the moment.
PS. Ideas for my scripts are coming from @Jegejig1 on Stocktwits, if you want to know who to blame lol
Trend Strength Directional IndicatorThis study was inspired by two famous Trading View contributors. Shout out to Lazy Bear and Crypto Face!
In this study you have a live view of the strength of direction the market is heading. The indicator that looks like a black wave is showing us the momentum of price action. When a green dot appears under the lower level it is a indication that we should consider buying, and if the red dot appears over the upper level we should sell. The custom MFI indicator determines how much money is flowing into the market.

The strategy includes a similar replication of the blue wave, and MFI indicator. The point of the strategy is to buy when the blue wave crosses up the zero value, and the MFI is greater than zero value. This indicates that there is strong bullish momentum and money flowing into the market.

[bjb] tEMAs - Triple Exponential Moving Averages, by BlueJayBirdIs it not a pain in the butt not to find a simple script like this one in TV? I didn't find one, so I made it.
Features:
- Simple script with 3 simple Exponential Moving Averages.
Special features:
- Settable time resolution.
- Colored fill between EMA20/50 pair, and between EMA50/200 pair.
More useful than you think:
- I've found it specially useful for detecting Elliot Wave patterns. The fill colors make them stand out. Use EMA20/50 pair for this.
- The resolution change makes EMAs studies from higher timeframes, at lower time frames, more accurate. Try from 1m timeframe, setting the tEMAs resolution to 1h.
