█ OVERVIEW
This library enhances TradingView's Pine Script with robust geometric capabilities. It introduces the Point and Line types, along with a suite of functions for various geometric operations. These functionalities empower you to perform advanced calculations, manipulations, and analyses involving points, lines, vectors, angles, and polygons directly within your Pine scripts. The example is at the bottom of the script. ( Commented out )
█ CONCEPTS
This library revolves around two fundamental types:
• Point: Represents a point in 2D space with x and y coordinates, along with optional 'a' (angle) and 'v' (value) fields for versatile use. Crucially, for plotting, utilize the `.to_chart_point()` method to convert Points into plottable chart.point objects.
• Line: Defined by a starting Point and a slope , enabling calculations like getting y for a given x, or finding intersection points.
█ FEATURES
• Point Manipulation: Perform operations like addition, subtraction, scaling, rotation, normalization, calculating distances, dot products, cross products, midpoints, and more with Point objects.
• Line Operations: Create lines, determine their slope, calculate y from x (and vice versa), and find the intersection points of two lines.
• Vector Operations: Perform vector addition, subtraction, multiplication, division, negation, perpendicular vector calculation, floor, fractional part, sine, absolute value, modulus, sign, round, scaling, rescaling, rotation, and ceiling operations.
• Angle Calculations: Compute angles between points in degrees or radians, including signed, unsigned, and 360-degree angles.
• Polygon Analysis: Calculate the area, perimeter, and centroid of polygons. Check if a point is inside a given polygon and determine the convex hull perimeter.
• Chart Plotting: Conveniently convert Point objects to chart.point objects for plotting lines and points on the chart. The library also includes functions for plotting lines between individual and series of points.
• Utility Functions: Includes helper functions such as square root, square, cosine, sine, tangent, arc cosine, arc sine, arc tangent, atan2, absolute distance, golden ratio tolerance check, fractional part, and safe index/check for chart plotting boundaries.
█ HOW TO USE
1 — Include the library in your script using:
import kaigouthro/geo/1
2 — Create Point and Line objects:
p1 = geo.Point(bar_index, close)
p2 = geo.Point(bar_index , open)
myLine = geo.Line(p1, geo.slope(p1, p2))
// maybe use that line to detect a crossing for an alert ... hmmm
3 — Utilize the provided functions:
distance = geo.distance(p1, p2)
intersection = geo.intersection(line1, line2)
4 — For plotting labels, lines, convert Point to chart.point :
label.new(p1.to_chart_point(), " Hi ")
line.new(p1.to_chart_point(),p2.to_chart_point())

Visual
Background ZonesThis script provides up to 5 zones to apply background colors. This is especially useful for applying to indices such as USI:TICK , USI:ADD , and USI:VOLD , where certain levels provides significant meaning to market sentiment and directions. This script will give you the visual cue to help with your trading.
All levels and colors are fully customizable.
Enjoy~!!
Example:
the FlasherBriefly flashes chart background colors as a visual alert whenever a condition occurs, from the insatiable mind of @scarf .
Special thanks to @LucF for his advice on improving efficiency when working with dynamic tables.
Close Combination Lock Style - Visual AppealThis creates a combination style closing price change on each tick.
It has two theme options, one as silver dials for Dark Theme and the other as black dials for White Theme.
We get fixated to watching closing prices on charts and it gets visually daunting. This creates a combination style price change which updates on each tick, which is quite pleasing to the eye.
When new price is above current center line, it shift the above prices showing ▲ arrow, and if new price is lower, it will shift the bottom prices showing ▼ arrow. If there is no change in price between the ticks, it will show =.
MA VisualizerThe MA Visualizer is made up of 5 Moving Averages (MA)
All MA change color when the price closes above or below the MA line.
The background between the MA line and price will also change color, this creates the Visualizer.
When two or more MA are selected the two visualizer's will combine and create a gradient effect.
Each MA can be adjusted with 6 source selection's to choose from (SMA , EMA , WMA , HMA , RMA , WVMA).
The Visualizer can be turned off while leaving the MA lines turned on and vice versa.
Their is also a MA Cross indicator built-in.
Heikin Ashi Candle OverlayHello Friend,
This is a very simple script for fun to demonstrate the new ability to change the colors of attributes pertaining to the plotbar() and plotcandle() functions using series inputs.
For Heiken Ashi lovers, this script does several things. It gives you both bars and hollow candles with Heikin Ashi values - something TV does not currently support.
It also gives you the ability to see your favorite HA candles while on the main series plot. When viewing indicators in the "Heikin Ashi" candle setting on TradingView, the input values are "smoothed' with HA values. This skews the way your indicators behave as the OLHC are calculated averages. Only the regular candle settings will give your indicators "real close" etc.
By 'Muting' the main series bars by toggling the 👁 symbol next to your ticker id, it makes the normal candles invisible. You then overlay this script, which allows you to see the HA Candle of your choice, while not affecting the way your indicators behave.
You now have the best of 2 worlds. Smoothed behavior of price action to help visualize trends, and accurate indicator values derived from actual OLHC data.
Plus, something about hollow HA candles is just kind of clean and soothing isn't it?
Cheers,
Bjorgum
Hollow Setting:
Bars
Or just plain old regular, but on the main chart
Visual Candlestick Blender (Analysis Tool), by @BlueJayBird- This is a analysis tool.
Brief Description
- It generates candlestick containers for current timeframe, using OPEN/HIGH/CLOSE/LOW data from higher time frames.
- Current version supports up to 4 CVB at the same time. Usually using only 2 is enough.
- Vertical extended divisions for 1h, 4h, 1D and 1W using background lines are included too.
* Report any bugs or feedback you have.
NOTE. At current unclosed candlestick , some weird line painting it is expected. It is not a bug, it is a Trading View feature that I haven't been able to solve yet. To solve this, setting the VCB off and then on should be enough.
Trading With Colors7 hours ago
Hello friends. This is simply a moving average ribbon, per se. The values for the colored ribbon can have their length calculated to fit their chosen resolution on the current one. This solved problems for me, but it was my own solution. Maybe I'll learn something new from sharing this.
To everybody else who is learning as well, this script essentially serves to introduce other time-frame moving averages. This intends to helps traders find the scope of relevance and not get lost in the current time-frame.
Besides the colored moving averages (2 sets, different resolutions, great zoomed in our out), I included optional check-boxes to allow comparison of sets of moving averages at will, so that the most important to the individual trader can be compared and selected specifically.
I kept the default options set to keep it clean. It likely won't be the only indicator on one's chart, so it's naturally best to reduce indicator noise from one, as to not subtract from the benefit of the other indicators.
I integrated tons of acquired knowledge into this, so I hope somebody finds a missing piece to their collection or a solution to a coding problem within. I also hope this provides a new insight and helps others on their path to financial freedom.
Best wishes.
PS: I left some old code in comments in case it helps to understand the evolution of my code. I'll update this again once it works on the Daily. You might figure it out before I do, in wish case, do share :)
Visual RSI [LucF]Visual RSI offers a different way of looking at RSI by providing a composite representation of 9 different RSI-generated components. Instead of focusing on one line only, this approach blends multiple sources to provide the viewer with a larger context RSI-based picture.
For those who don’t want to read
• Green in bullish (>50) zone is the most bullish.
• Red in bullish zone doesn’t necessarily mean bearish—it just means bullish strength is weakening. It may be just a pause before a reprise or exhaustion signalling a reversal—impossible to tell.
• The same in inverse applies to the bearish zone (<50).
For those who want to understand
The nine components making up Visual RSI are:
• a current timeframe RSI
• a higher timeframe RSI
• the delta between these two RSI lines
• for each of these three basic components, two independent Bollinger band: one calculated for the bullish section of the scale (>50) and a separate one calculated for the lower bearish region.
Dual BBs
In my view, RSI’s position with regards to the centerline is much more important than its position in extreme areas. Why? Because the building block of RSI is the ratio of the averages of up/down moves during the RSI period. When the average of ups is greater, RSI is > 50. So while a rising signal starting from 20 let’s say, indicates that the rate of change is increasing, only when it crosses 50 can we say that sentiment balance has truly become bullish, and this information is more reliable than the signal being at a level corresponding to whatever estimate we make of what constitutes an extreme value. In my landscape, the general balance of a ratio provides more valuable information than the ratio’s exact value.
The idea behind the dual BBs is to provide independent tracking information for both halves of the indicator’s space, which I find more useful than the normal method of simply adding a multiple of the standard deviation on both sides of the mean. With dual BBs, the upper BB will never go lower than the indicator’s centerline, and the lower BB will never go higher. The upper BB focuses on upper-bound volatility when the signal is bearish, and the lower BB focuses on downside volatility when the signal is bearish.
The functions used to calculate the independent BBs are reusable on other signals if a centerline can be defined for them. A clamping percentage is implemented, so that when a BB line is hugging the centerline it clamps to it. This helps in providing earlier signals when they use the BB line states.
Providing context to RSI
What RSI measures indirectly is the balance in the rate of change—or the speed of price movement, but not its instant value, otherwise RSI would be even noisier. More precisely, RSI represents the relative strength of the up/down movement in the last n bars of RSI’s length, with 14 often used because that’s what Wilder proposed (Visual RSI’s defaults are 20 for the current timeframe and 40 for the higher timeframe). At every bar, a new value is added to the equation and an old value carrying equal weight is dropped, so a large dropped off value will have more impact on RSI’s value if the new bar’s move is small. This accounts for some of RSI’s speed in identifying exhaustion after important moves, but almost for some of its noise.
Visual RSI is the result of trying to drown RSI’s noise in the context of other informational streams, while simultaneously providing even faster information than RSI alone, by giving more visual weight to the delta between the current and higher timeframe RSI’s.
How to read Visual RSI
The default settings show all 9 basic components as green/red areas of intensities varying with their importance. The most intense colors are reserved for the delta RSI and the BBs have the lightest intensities. The individual lines of components are intentionally difficult to distinguish so that focus is first on the general picture, including the all-important six-state background, and then on the delta RSI.
One entry setup could be reversals in a larger trend context, so low pivots of the delta in a fully bullish context (a green background in the upper section of the indicator), and inversely, high pivots in a fully bearish context (a red background in the lower section of the indicator).
Please resist the common misconception, when interpreting RSI, that a reversal in the signal will necessarily lead to a reversal in price. Each trend has its rhythm. Only machine-generated price action can progress regularly. It’s normal for trends to take a breather for some time before they continue or reverse, as traders driving the trend experience emotional fatigue and gradual fear. RSI reversals merely signify that such a breather has occurred—nothing more. Only the larger context can provide information that can situate that pause and put more meaningful odds on it having more probability of continuing in one direction or the other. This is the reasoning behind the setup just described.
Features
• All components can be hidden, displayed as a simple line, a uniformly colored fill, or a green/red fill (the default).
• The background can be colored using 9 different methods, including 3 six-state methods using the rising/falling BB lines of the 3 basic components. These six states allow for bullish/bearish/neutral sentiment in both the upper and lower regions of the indicator. A bearish (dark red) background in the bullish (>50) section of the indicator represents decreasing bullishness. A bearish (slightly brighter red) in the bearish (<50) section of the indicator means incresingly bearish sentiment. The six-state backgrounds allow for neutral (no color) sentiment when no compelling signs can be found to conclude anything with meaningful odds. The default background uses the six-state method on the higher timeframe RSI’s BBs because I find it the most useful, as it represents the largest—and slowest—context sentiment among all the indicator’s components.
• A thin status bar in the top part of the indicator also allows selection of the same 9 methods to color it. The default is a triple-state system using the rising/falling characteristics of the current timeframe RSI’s BBs to provide a short-term counterbalance to the long-term background.
• Three different markers can be configured using approximately 70 permutations each, each filtered by 20 different filter permutations. When modification of the relevant parameters in the script’s Settings/Settings/Parameters section is added, possibilities are almost endless. If the generated signals are then fed into the PineCoders Engine and combined with the Engine’s own options, the permutations go up another order of magnitude, and changes to any setting can be instantly evaluated using the Engine’s backtesting results.
• Five simple filters can be combined. They are additive. They include volume-related conditions and a chandelier, which I find useful because both volume and volatility (the chandelier using highs/lows and ATR) are sensible complementary sources to RSI’s momentum information. The filter’s state can be shown as a thin line at the bottom of the indicator.
• Alerts can be configured using any of the marker/filter combinations mentioned. As usual, once your markers/filters are set up the way you want, create your alert from the chart/timeframe you want the alert to run on and be sure to use the “Once Per Bar Close” triggering condition. Use an alert message that will remind you of which combination of markers were used when creating the alert.
• A plot providing entry signals for the PineCoders Backtesting & Trading Engine is supplied. It will use whichever marker/filter configuration is active to generate signals.
• All higher timeframe information is non-repainting. Higher timeframe lines can be smoothed (the default). The selection of the higher timeframe can be made using 3 different methods:
1. By steps (if current timeframe <= 1 minute: 60 min, <= 60 min: 1D, <= 6H: 3D, <= 1D: 1W, <=1W: 1M, >1W: 12M)
2. By a user-defined multiple of the current timeframe
3. Using a fixed timeframe

Multi BB Heat Vis - SMA/EMA/Breakout - r2I don't expect to iterate any further on this script, unless any weird issue crops up.
Description and usage detailed in the comments at the top of the script. Cheers!
To repaint or not to repaint, all the relevant sources are exposed as inputs for customisation - so the choice is yours.
Cheers!
Price above/below EMAThis script will give you red/green columns to indicate if price is above or below a certain EMA. With Candlestick charting, we are looking for price in relation to the 8 ema Trigger Line (T-Line). You can adjust this indicator to fit your need. Simple, but nice to quickly see.
Oops. Last line's title should be "Sell". Doesn't affect display though.
