BUY/SELL SIGNALS from LSMA/ALMA/HMAThis indicator uses the Least Squares Moving Average (LSMA) in tandem with the Arnaud Legoux Moving Average (ALMA) and Hull Moving Average (HMA) to generate buy-sell signals, represented by the light blue and orange crosses respectively.
The yellow lines produced by the indicator show periods of market uncertainty and possible reversal, and a modified, user-defined VWAP is given along with a 200 EMA. The point of this indicator was to create a smoother, more visually appealing moving-average, price action-based indicator when compared to the trend-step and simple moving average indicators available. This indicator uses a fast (25 period) LSMA coupled with a slower (50 period) HMA and ALMA in order to make signals both smooth and fast.
This indicator will work on all markets, except the modified VWAP will naturally not function if the volume is unpublished for that market. Use of this indicator will be very strong in trending markets, as the yellow line will spot possible reversals quite early, meaning the trader can be ready early for the buy/sell signal to appear. Use of this indicator in sideways market conditions will be limited, as it is for all moving average-based indicators, but the damage will be minimal as bad trades will be quickly realized by the indicator and the color will switch to yellow, this is possible because of the settings differences between the period lengths of the LSMA vs the ALMA + HMA.
BarRange vs VolumeThis is a volume spread analysis/ breadth type indicator.
Compares average bar size to the average volume. Looks for small bar and high volume.
Percentage Levels by TimeframePlots the positive and negative percentage levels from a selection of timeframes and sources for any ticker. You can use this within a pullback trading system. For example, if you historically look at the average pullback of large cap stocks and ETF's, you can use this indicator to plot the levels it could pullback to for an entry to go long. It can be used as potential targets when trading a ticker short. Another use for this is to backtest the set percentage targets using TradingView's bar replay feature to see how ETF's and large cap stocks have reacted at these levels. Note: This is intended to be used at timeframes equal to higher than the chart's as it may cause re-painting issues.
Currently percentage levels are statically set to 1, 3, 5, 10, 15, 20, 25, and 30% levels above and below the chosen source (open, high, low, close). You can also display the data based on timeframes from Daily (1D) all the way up to Yearly (12M)
*Not financial advice but in my opinion the current percentage levels set (see above) are best used for ETF's and Large Cap Stocks.

200DMA last DOM - ajhImplements and backtests a simple 200 day moving average trend following rules based on last day of month to limits trades to 12 per year.
From the book : 5 BEST Moving Average Strategies (That beat buy and hold) by Steve Burns and Holly Burns
Click on the cog to set the input date range eg; 2000-01-01 to 2016-12-31
The book back tested SP500 returns from 2000-2016 317% using this method vs 125% buy and hold only with less drawdown.
Simple 200 day moving average test and trading on last day of month.
(you may find it trades on next available day close to end of month as not all dates can be traded weekends etc..)
Rules are ;
1. if last day of month and stock over 200 day moving average, then go long 100%
2. if last day of month and stock under 200 day moving average, then close long 100% and goto cash.
Aims to miss market declines and keep you long for upside.
Note: Have found doesn't work well in choppy markets moving sideways like the FTSE100 for same period 2000-2016 and causes losses. Also for many stocks.
Abz Bonds/BTC divergenceDraft release: This indicator shows the comparative returns from US bonds vs BTC.
I was inspired by this Twitter thread: twitter.com
If you compare the price action of Bitcoin against bond returns over the last year, there's an extraordinary degree of correlation. This may give insights into what's coming next for BTC , but at some point the relationship will inevitably break down. In the meantime, there's much to gain.
DYOR.
Feedback welcome though it may take a while for me to respond.
[mdeacey] EMA% Channel + BB Range StrategyThis strategy is based off the users selection of an EMA and percentage defined channel. The strategy longs when a red "reversal candle" (that exceeds the averages of 3 and 9 above the EMA 3) is found until such time that either the price goes outside the Bollinger Band or the green reversal candle is found. The same but opposite process for shorts. If the price begins trending and moves outside the channel all trades are exited to prevent loss.
For trending markets the sister strategy (" EMA% Channel + Bollinger Band Trending Strategy") should instead be used.
The obvious fallback to this strategy is that:
- If the bands are too wide we don't have a good definition of trending vs ranging and the price can move up/down significantly and trend whilst remaining within the ranging channel. We try to mitigate this through use of a stoploss defined by ATR and a pretty tight channel. This is a tightrope exercise as making the percentage channels tighter misses earlier entries in optimal cases. Change the parameters to find an EMA and percentages to find the best R/R in your case.
Potential further iteration:
- It would be good to see if the R/R changes positively if we only allow shorts above the EMA and longs below it.
All options are configurable and code open source. Happy trading!
Bybit perp discount vs Coinbase BTCThis indicator shows the discount Bybit BTC perp is trading at relative to Coinbase.
Relative Strength vs SPY - real time & multi TF analysisOne of the most requested features for TradingView is the ability to include custom indicators in the stock market scanner. While I am sure this feature is coming soon (seriously TV, PLEASE) I decided to use the amazing template provided by QuantNomad (), but I wanted to allow the user to modify the table a bit better so that a multi time frame analysis approach could be used.
The recommended way to use this indicator is to apply it three times to your chart. For each instance, assign it a plotting location (left, center, right) and choose the timeframe you wish to use for the RS analysis. By default, the relative strength of all 39 pre selected stocks will be compared against SPY, on the 5 min timeframe. I personally like having this chart on the left, then the 4 hour timeframe in the center, and the daily on the right. Not only does this setup allow you to see the relative strength/weakness of 39 stocks in real time (the one on the left), but you have all the information in front of you including how the stock has been performing relative to SPY on the 4H and D charts.
To make it easiest to read, you should disable all visual elements to the chart you are applying this indicator to. By minimizing the chart and putting it by your side, you can see the bigger picture on how all your stocks are behaving relative to the market.
If you wish to change any of the stocks I have pre selected, make sure to save your chart template. Otherwise you would need to do this every time you load the indicator to your chart which would be incredibly time consuming.
:: Magic Osc The "Magic Oscillators" indicator is based on 4 points:
1. RSI with MA filter
2. A logarithmic MA of the price
3. A “squeeze” of the price (points on the “0” line and the light blue background)
4. The up and down signals, which indicate the trend direction, based on the price vs EMA 50 relationship.
Extra - A "long term" filter with input signal - again MA.
All values are possible to adjust to needs/setup.
The indicator is only to help in quicker and more effective technical analysis and not as entry/exit trading signals.
The indicator can be used and the code modified depending on the interests of each trader.
Good trades...
ATR vs Daily DeltaThis indicator follows the idea of the average true range indicator, but splits red candles from green candles. It also displays daily deltas as a histogram chart. Finally, it allows you to "normalize" the indicator, which displays period percentage moves (shown in decimal form) instead of period deltas, and calculates the ATR from those percentages instead of period deltas.
Half-Pi Cycle CKB top indicator (insanely experimental)This is an insanely experimental script. It's a modified version of the Bitcoin pi-cycle top indicator.
It changes the Bitcoin pi-cycle top formula by halving the number of days in the two DMAs used in calculation, from 350/111 to 175/56. So I call it the half-pi cycle. It correctly picked the top of CKB (Nervos Network) vs USDT on Huobi in spring 2021 within three days.
It probably is a coincidence, and could very easily not pick the next cycle peak correctly at all. Using such a short number of days makes it a little dubious, but I had no choice since there's only so much price history for this coin. I strongly advise you to not make any trades based on this script ! I cannot be held accountable if you lose money due to this script. It hasn't been shown to be accurate multiple times like the Bitcoin pi-cycle top indicator. I simply find this interesting and want to see if it works next time.
Instrument-Z (3Commas Bot)Instrument-Z is what I am currently using as my 3Commas Bot.
It allows you to customize signals from 3 indicators; Crossing MA's, Stochastic RSI, and WaveTrend.
Better yet, it allows you to setup these signals separately depending on whether the Trend MA is going up or down.
So there are 2 sets of inputs for everything, Uptrend inputs and Downtrend inputs.
I have realized that we can't expect a strategy to work the same way in an uptrend vs downtrend, so the inputs should be separated too.
In my testing, separating increased the net profit by 60% on average.
You can select whether you are trading Long or Short.
You can choose your stop loss and take profit levels as well as trade expiration.
You can choose if you only want to trade with the trend (making the opposing signals irrelevant).
The trend is based on the Trend MA.
This script is specifically for cryptocurrencies.
I've noticed that MA crosses on other asset classes are unreliable because the fluctuations are not strong enough to push the MA's across each other in a meaningful way.
If you want to use this as a 3Commas Bot, then you will have to copy the code of the strategy and paste it into your own personal script.
Then you have to change the alert messages at the bottom of the script.
Make sure to change your alert message from this;
{"message_type": "bot", "bot_id": 0000000, "email_token": "0b000a0a-0aa0-00aa-0aa0-000a00000a0a", "delay_seconds": 0}
To this;
{\n\"message_type\": \"bot\",\n\"bot_id\": 0000000,\n\"email_token\": \"0a000a0a-0aa0-00aa-0aa0-000a00000a0a\",\n\"delay_seconds\": 0\n}
With \n after each new line and \ before each quotation.
In the Alert setup, select "alert() function calls only".
This indicator is like a middle ground of complexity between the Juicy Trend indicator and the Instrument-A indicator.
And because it does not feature my neural network project, I have made it open script.
Enjoy!
Smoothed Heiken Ashi - SamXThis is my version of the Smoothed Heiken Ashi indicator. While there are a few versions of these out there (most notably "Modified Smoothed Heiken Ashi" by badshah_e_alam and "Smoothed Heiken Ashi Candles v1" by jackvmk), none matched what I was looking for.
1. All had hard-coded the smoothing to use the EMA calculation - in this indicator, these are user-configurable
2. Both applied the double-smoothing principle (Take a moving-average of price, apply the Heiken Ashi conversion, then apply a second moving average to the smoothed Heiken Ashi candles to calculate new candles). While this is the most common approach, I had a few issues with this:
Even if setting both moving average lengths to 1, the indicator did not correctly calculate what should be the actual corresponding Heiken Ashi candle values (as compared to the built-in Heiken Ashi chart on Tradingview)
They were inconsistent in operating on different chart types - indicator values for the same candle can differ between using a base Heiken Ashi or Renko chart vs a standard Candle or Bar chart.
I wanted the ability to easily enable/disable the second smoothing (which is now a configuration option)
I wanted the ability to configure different moving-average calculations for each smoothing iteration (e.g. EMA for the initial smoothing, and Smoothed Moving Average for the second smoothing)
3. Many of the inputs were not clearly or properly defined in the settings window - this script has far more refined user input settings, put in logical groupings, and with relevant help text.
4. Enhanced some visual styling (and added to the Settings) to make it easier for the user to enable/disable printing candle wicks, as well as customizing the bullish / bearish bar colors
5. Added alerts for bar color change to help users catch potential trend reversals

Volume x Price in Crores + RVolScript is designed predominantly for Indian users. Many are used to looking at numbers in lakhs and crores vs millions and billions, this provides a volume figure in rupee crores.
Formula is last close_price x volume / 1 cr or (close_price x volume /10000000). The second figure is the simple moving average (default to 20sma ) again in rupee crores. The third is the relative volume - todays volume / 20 day moving average.
Helpful especially when putting on a trade for a thinly traded stock. It is a quick gauge to how large or small one would want to buy or avoid. Helps manage risk. Also, great to see large volumes in crores to gauge institutional buys or sells.
On 10/NOV/21 - In the chart displayed here, Titan volumes are on average quite substantial as one can see. The 20 day moving average is 550 CR+. 10/NOV volumes are shown as 226 CR and the RVOL is 0.41 (226/550).
Volume PressureBreaks down volume into buyers (green part) vs sellers (red part).
It is recommended to set the volume's scale, especially if you switch tickers on the same chart. Follow these steps:
Select the Volume Pressure indicator's 3 dots (...)
Select Pin To Scale
Select a separate scale from the main chart, such as Pin To New Left Scale (Z)
Left click and hold the scale on the side of the chart and drag it up/down to bring the volume bars into the desired area
To update to the latest version, just close the indicator and add it again.
UT Bot v5This is an update by request, on someone elses strategy! well more of an edit, but also update from pine v4 to pine v5.
//CREDITS to HPotter for the orginal code. The guy trying to sell this as his own is a scammer lol.
//Edited and converted to @version=5 by SeaSide420 for Paperina
The UT Bot v5 is Movinging average (the MA) vs ATR (the ATR is in the form intended for use as trailing stop loss (ATR_TSL))
Entry logic:
buy = the MA > ATR_TSL and Price > ATR_TSL
sell = the MA < ATR_TSL and Price < ATR_TSL
The Moving average type can be changed in the settings:
options = "SMA", "EMA", "WMA", "HMA"]
the edits i made were:
convert to v5
Add TP and SL
Add Buy only or Sell only option
Add MA type option
Add price source option
Draw MA and ATR_TSL on-chart
Dogecoin vs DogToken Dominance %This script plots the Dogecoin dominance against other meme dog tokens like Shiba Inu , Akita Inu and Dogelon .

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.

[jav] Better Bollinger BandsBetter Bollinger Bands (BBB)
This script is a modification of classic Bollinger Bands (BB).
CHARACTERISTICS
Main improvement over BB:
There is no need to introduce a standard deviation multiplier (usually 2).
Here, only a length is needed (usually 20 bars for BB).
Other features:
The type of moving average can be selected: sma, ema, vwma, wma or rma.
An inner band is plotted as an additional indication of approaching extreme levels.
Classic BB can also be shown on the graph for the sake of comparison.
CALCULATIONS
The calculation of BBB is done by adding three different contributions:
Standard deviation of price
Standard deviation of (price minus moving average)
Average of (high - low) over length.
RESULTS
It looks like BBB follows prices more smoothly (without the typical overshoots of BB). Also, it fits extreme values with higher accuracy. Finally, usually it doesn't cross through prices at less relevant, intermediate higher highs or lower lows, which can be advantageous.
See the comparison between red BBB vs blue BB:
Both vwma and ema seem to give decent BBB values using the standard length of 20 bars.
Forex Trading SessionsThere are a million Forex Trading Session indicators out there, but I couldn't find one with all of the following requirements:
1. Automatically show the Sessions that actually affect the current pair (for instance, Tokyo session doesn't matter when trading EURGBP)
2. Editable colors or at the very least no distracting colors
3. Editable times for each exchange session
4. Unique indication of the start of a session vs the end of a session. (Sometimes, I don't notice a background going from Navy Blue to Black)
This indicator has everything I could ever want in a Sessions Tool:
Subdued default colors
Editable colors
Editable session ranges
Obvious, but not obnoxious indication of start and stop
Automatically hide irrelevant Sessions
