BasicVisibleChartBasic library for the visible range chart; with functions to allow plotting Fibs from body high/low as well as wick high/low
-Thanks to code from @PineCoders Visible Chart library (PineCoders/VisibleChart/4), which is a much more comprehensive library than this, but which does not include some functions that I find useful:
-Added the following exportable functions: highest/lowest body, highest/lowest close, highest/lowest open. These allow one to anchor fibs from bodies rather than wicks
-Added a Fib Box function in the example code
The above chart shows the example code plotting a Fib range drawn from bodies and a highlighted retracement zone (61.8 % - 78.6% )

TrailingStopsLibrary "TrailingStops"
This library contains functions to output trailing stop lines.
f_marketStructureStop(_restartMode, _flipMode, _restartLowIn, _restartHighIn)
Parameters:
_restartMode - Defines how the stop lines persist. Allowed values are:
"Always On" - The stop lines are always present and they just reset when they're crossed.
"Flip" - The stop lines flip when they're crossed.
"Manual" - The stop lines turn off when they're crossed, and turn back on again when _restartLowIn or _restartHighIn are passed into the function as true.
_flipMode - Defines whether the stop lines are broken by wicks or closes. Allowed values are "Wick", and "Close".
_restartLowIn - If _restartMode is "Manual", passing this parameter as true restarts the Low stop line.
_restartHighIn - If _restartMode is "Manual", passing this parameter as true restarts the High stop line.
@returns - floats for the Low and High stop line.
MarketStructureLibrary "MarketStructure"
This library contains functions for identifying Lows and Highs in a rule-based way, and deriving useful information from them.
f_simpleLowHigh()
This function finds Local Lows and Highs, but NOT in order. A Local High is any candle that has its Low taken out on close by a subsequent candle (and vice-versa for Local Lows).
The Local High does NOT have to be the candle with the highest High out of recent candles. It does NOT have to be a Williams High. It is not necessarily a swing high or a reversal or anything else.
It doesn't have to be "the" high, so don't be confused.
By the rules, Local Lows and Highs must alternate. In this function they do not, so I'm calling them Simple Lows and Highs.
Simple Highs and Lows, by the above definition, can be useful for entries and stops. Because I intend to use them for stops, I want them all, not just the ones that alternate in strict order.
@param - there are no parameters. The function uses the chart OHLC.
@returns boolean values for whether this bar confirms a Simple Low/High, and ints for the bar_index of that Low/High.
f_localLowHigh()
This function finds Local Lows and Highs, in order. A Local High is any candle that has its Low taken out on close by a subsequent candle (and vice-versa for Local Lows).
The Local High does NOT have to be the candle with the highest High out of recent candles. It does NOT have to be a Williams High. It is not necessarily a swing high or a reversal or anything else.
By the rules, Local Lows and Highs must alternate, and in this function they do.
@param - there are no parameters. The function uses the chart OHLC.
@returns boolean values for whether this bar confirms a Local Low/High, and ints for the bar_index of that Low/High.
f_enhancedSimpleLowHigh()
This function finds Local Lows and Highs, but NOT in order. A Local High is any candle that has its Low taken out on close by a subsequent candle (and vice-versa for Local Lows).
The Local High does NOT have to be the candle with the highest High out of recent candles. It does NOT have to be a Williams High. It is not necessarily a swing high or a reversal or anything else.
By the rules, Local Lows and Highs must alternate. In this function they do not, so I'm calling them Simple Lows and Highs.
Simple Highs and Lows, by the above definition, can be useful for entries and stops. Because I intend to use them for trailing stops, I want them all, not just the ones that alternate in strict order.
The difference between this function and f_simpleLowHigh() is that it also tracks the lowest/highest recent level. This level can be useful for trailing stops.
In effect, these are like more "normal" highs and lows that you would pick by eye, but confirmed faster in many cases than by waiting for the low/high of that particular candle to be taken out on close,
because they are instead confirmed by ANY subsequent candle having its low/high exceeded. Hence, I call these Enhanced Simple Lows/Highs.
The levels are taken from the extreme highs/lows, but the bar indexes are given for the candles that were actually used to confirm the Low/High.
This is by design, because it might be misleading to label the extreme, since we didn't use that candle to confirm the Low/High..
@param - there are no parameters. The function uses the chart OHLC.
@returns - boolean values for whether this bar confirms an Enhanced Simple Low/High
ints for the bar_index of that Low/High
floats for the values of the recent high/low levels
floats for the trailing high/low levels (for debug/post-processing)
bools for market structure bias
f_trueLowHigh()
This function finds True Lows and Highs.
A True High is the candle with the highest recent high, which then has its low taken out on close by a subsequent candle (and vice-versa for True Lows).
The difference between this and an Enhanced High is that confirmation requires not just any Simple High, but confirmation of the very candle that has the highest high.
Because of this, confirmation is often later, and multiple Simple Highs and Lows can develop within ranges formed by a single big candle without any of them being confirmed. This is by design.
A True High looks like the intuitive "real high" when you look at the chart. True Lows and Highs must alternate.
@param - there are no parameters. The function uses the chart OHLC.
@returns - boolean values for whether this bar confirms an Enhanced Simple Low/High
ints for the bar_index of that Low/High
floats for the values of the recent high/low levels
floats for the trailing high/low levels (for debug/post-processing)
bools for market structure bias
TechnicalRating█ OVERVIEW
This library is a Pine Script™ programmer’s tool for incorporating TradingView's well-known technical ratings within their scripts. The ratings produced by this library are the same as those from the speedometers in the technical analysis summary and the "Rating" indicator in the Screener , which use the aggregate biases of 26 technical indicators to calculate their results.
█ CONCEPTS
Ensemble analysis
Ensemble analysis uses multiple weaker models to produce a potentially stronger one. A common form of ensemble analysis in technical analysis is the usage of aggregate indicators together in hopes of gaining further market insight and reinforcing trading decisions.
Technical ratings
Technical ratings provide a simplified way to analyze financial markets by combining signals from an ensemble of indicators into a singular value, allowing traders to assess market sentiment more quickly and conveniently than analyzing each constituent separately. By consolidating the signals from multiple indicators into a single rating, traders can more intuitively and easily interpret the "technical health" of the market.
Calculating the rating value
Using a variety of built-in TA functions and functions from our ta library, this script calculates technical ratings for moving averages, oscillators, and their overall result within the `calcRatingAll()` function.
The function uses the script's `calcRatingMA()` function to calculate the moving average technical rating from an ensemble of 15 moving averages and filters:
• Six Simple Moving Averages and six Exponential Moving Averages with periods of 10, 20, 30, 50, 100, and 200
• A Hull Moving Average with a period of 9
• A Volume-Weighted Moving Average with a period of 20
• An Ichimoku Cloud with a conversion line length of 9, base length of 26, and leading span B length of 52
The function uses the script's `calcRating()` function to calculate the oscillator technical rating from an ensemble of 11 oscillators:
• RSI with a period of 14
• Stochastic with a %K period of 14, a smoothing period of 3, and a %D period of 3
• CCI with a period of 20
• ADX with a DI length of 14 and an ADX smoothing period of 14
• Awesome Oscillator
• Momentum with a period of 10
• MACD with fast, slow, and signal periods of 12, 26, and 9
• Stochastic RSI with an RSI period of 14, a %K period of 14, a smoothing period of 3, and a %D period of 3
• Williams %R with a period of 14
• Bull Bear Power with a period of 50
• Ultimate Oscillator with fast, middle, and slow lengths of 7, 14, and 28
Each indicator is assigned a value of +1, 0, or -1, representing a bullish, neutral, or bearish rating. The moving average rating is the mean of all ratings that use the `calcRatingMA()` function, and the oscillator rating is the mean of all ratings that use the `calcRating()` function. The overall rating is the mean of the moving average and oscillator ratings, which ranges between +1 and -1. This overall rating, along with the separate MA and oscillator ratings, can be used to gain insight into the technical strength of the market. For a more detailed breakdown of the signals and conditions used to calculate the indicators' ratings, consult our Help Center explanation.
Determining rating status
The `ratingStatus()` function produces a string representing the status of a series of ratings. The `strongBound` and `weakBound` parameters, with respective default values of 0.5 and 0.1, define the bounds for "strong" and "weak" ratings.
The rating status is determined as follows:
Rating Value Rating Status
< -strongBound Strong Sell
< -weakBound Sell
-weakBound to weakBound Neutral
> weakBound Buy
> strongBound Strong Buy
By customizing the `strongBound` and `weakBound` values, traders can tailor the `ratingStatus()` function to fit their trading style or strategy, leading to a more personalized approach to evaluating ratings.
Look first. Then leap.

Zig Zag is a popular indicator that filters out minor price fluctuations to denoise data and emphasize trends. Traders commonly use Zig Zag for trend confirmation, identifying potential support and resistance, and pattern detection. It is formed by identifying significant local high and low points in alternating order and connecting them with straight lines, omitting all other data points from their output. There are several ways to calculate the Zig Zag's data points and the conditions by which its direction changes. This script uses pivots as the data points, which are the highest or lowest values over a defined number of bars before and after them. The direction only reverses when a newly formed pivot deviates from the last Zig Zag point in the opposite direction by an amount greater than or equal to a specified percentage.
To learn more about Zig Zag and how to calculate it, see this entry from the Help Center.
█ FOR Pine Script™ CODERS
Notes
This script's architecture utilizes user-defined types (UDTs) to create custom objects which are the equivalent of variables containing multiple parts, each able to hold independent values of different types . UDTs are the newest addition to Pine Script™ and the most advanced feature the language has seen to date. The feature's introduction creates a new runway for experienced coders to push the boundaries of Pine. We recommend that newcomers to the language explore the basics first before diving into UDTs and objects.
Demonstration Code
Our example code shows a simple use case by displaying a Zig Zag with user-defined settings. A new ZigZag object is instantiated on the first bar using a Settings object to control its attributes. The fields for the Settings object are declared using variables assigned to input.* functions, allowing control of the field values from the script's settings. The `update()` function is invoked on each bar to update the ZigZag object's fields and create new lines and labels when required.
Look first. Then leap.
█ TYPES
This library contains the following types:
Settings
Provides calculation and display attributes to ZigZag objects.
Fields:
devThreshold : The minimum percentage deviation from a point before the ZigZag will change direction.
depth : The number of bars required for pivot detection.
lineColor : Line color.
extendLast : Condition allowing a line to connect the most recent pivot with the current close.
displayReversalPrice : Condition to display the pivot price in the pivot label.
displayCumulativeVolume : Condition to display the cumulative volume for the pivot segment in the pivot label.
displayReversalPriceChange : Condition to display the change in price or percent from the previous pivot in the pivot label.
differencePriceMode : Reversal change display mode. Options are "Absolute" or "Percent".
draw : Condition to display lines and labels.
Point
A coordinate containing time and price information.
Fields:
tm : A value in UNIX time.
price : A value on the Y axis (price).
Pivot
A level of significance used to determine directional movement or potential support and resistance.
Fields:
ln : A line object connecting the `start` and `end` Point objects.
lb : A label object to display pivot values.
isHigh : A condition to determine if the pivot is a pivot high.
vol : Volume for the pivot segment.
start : The coordinate of the previous Point.
end : The coordinate of the current Point.
ZigZag
An object to maintain Zig Zag settings, pivots, and volume.
Fields:
settings : Settings object to provide calculation and display attributes.
pivots : An array of Pivot objects.
sumVol : The volume sum for the pivot segment.
extend : Pivot object used to project a line from the last pivot to the last bar.
█ FUNCTIONS
This library contains the following functions:
lastPivot(this)
Returns the last Pivot of `this` ZigZag if there is at least one Pivot to return, and `na` otherwise.
Parameters:
this : (series ZigZag) A ZigZag object.
Returns: (Pivot) The last Pivot in the ZigZag.
update(this)
Updates `this` ZigZag object with new pivots, volume, lines, labels.
Parameters:
this : (series ZigZag) a ZigZag object.
Returns: (bool) true if a new Zig Zag line is found or the last Zig Zag line has changed.
newInstance(settings)
Instantiates a new ZigZag object with `settings`. If no settings are provided, a default ZigZag object is created.
Parameters:
settings : (series Settings) A Settings object.
Returns: (ZigZag) A new ZigZag instance.
