Trend Analysis — Indicators and Strategies

BasicVisibleChart Basic 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% ) ~~All Exportable Functions~~ barIsVisible() highestClose() highestOpen() highestBody() lowestClose() lowestOpen() lowestBody() high() highBarTime() low() lowBarTime() open() close()

AutoFiboRetrace Library "AutoFiboRetrace" TODO: add library description here fun(x) TODO: add function description here Parameters: x : TODO: add parameter x description here Returns: TODO: add what function returns

merge_pinbar Library "merge_pinbar" merge_pinbar: merge bars and check whether the bar is a pinbar merge_pinbar(simple, simple) merge_pinbar: merge bars and check whether the bar is a pinbar Parameters: simple : int period: the statistic bar period simple : int max_bars: the max bars to be merged Returns: array:

PivotPointsDailyTraditional Library "PivotPointsDailyTraditional" Provides the traditional daily pivot values and a pivot vacinity function. P(level, daysPrior) Returns the P value. Parameters: level : The level to caclulate. daysPrior : The number of days in the past to do the calculation. R(level, daysPrior) Calculates the R value for a given pivot level. Parameters: level : The level to caclulate. daysPrior : The number of days in the past to do the calculation. S(level, daysPrior) Calculates the S value for a given pivot level. Parameters: level : The level to caclulate. daysPrior : The number of days in the past to do the calculation. vacinity(value, daysPrior, maxLevel) Returns a value representing where the provided value is in relation to each pivot level. Parameters: value : The value to compare against. daysPrior : The number of days in the past to do the calculation. maxLevel : The maximum number of pivot levels to include.

CandleEvaluation Library "CandleEvaluation" Contains functions to evaluate bullish and bearish, engulfing, and outsized candles. They are different from the built-in indicators from TradingView in that these functions don't evaluate classical patterns composed of multiple candles, and they reflect my own understanding of what is "bullish" and bearish", "engulfing", and "outsized". isBullishBearishCandle() Determines if the current candle is bullish or bearish according to the length of the wicks and the open and close. int _barsBack How many bars back is the candle you want to evaluate. By default this is 0, i.e., the current bar. returns Two values, true or false, for whether it's a bullish or bearish candle respectively. isTripleBull() Tells you whether a candle is a "Triple Bull" - that is, one which is bullish in three ways: It closes higher than it opens It closes higher than the body of the previous candle The High is above the High of the previous candle. int _barsBack How many bars back is the candle you want to evaluate. By default this is 0, i.e., the current bar. returns True or false. isTripleBear() Tells you whether a candle is a "Triple Bear" - that is, one which is bearish in three ways: It closes lower than it opens It closes lower than the body of the previous candle The Low is below the Low of the previous candle. int _barsBack How many bars back is the candle you want to evaluate. By default this is 0, i.e., the current bar. returns True or false. isBigBody() Tells you if the current candle has a larger than average body size. int _length - The length of the sma to calculate the average float _percent - The percentage of the average that the candle body has to be to count as "big". E.g. 100 means it has to be just larger than the average, 200 means it has to be twice as large. returns True or false isBullishEngulfing() Tells you if the current candle is a bullish engulfing candle. int _barsBack How many bars back is the candle you want to evaluate. By default this is 0, i.e., the current bar. int _atrFraction The denominator for the ATR fraction, which is the small amount by which the open can be different from the previous close. returns True or false isBearishEngulfing() Tells you if the current candle is a bearish engulfing candle. int _barsBack How many bars back is the candle you want to evaluate. By default this is 0, i.e., the current bar. int _atrFraction The denominator for the ATR fraction, which is the small amount by which the open can be different from the previous close. returns True or false

CreateAndShowZigzag Library "CreateAndShowZigzag" Functions in this library creates/updates zigzag array and shows the zigzag getZigzag(zigzag, prd, max_array_size) calculates zigzag using period Parameters: zigzag : is the float array for the zigzag (should be defined like "var zigzag = array.new_float(0)"). each zigzag points contains 2 element: 1. price level of the zz point 2. bar_index of the zz point prd : is the length to calculate zigzag waves by highest(prd)/lowest(prd) max_array_size : is the maximum number of elements in zigzag, keep in mind each zigzag point contains 2 elements, so for example if it's 10 then zigzag has 10/2 => 5 zigzag points Returns: dir that is the current direction of the zigzag showZigzag(zigzag, oldzigzag, dir, upcol, dncol) this function shows zigzag Parameters: zigzag : is the float array for the zigzag (should be defined like "var zigzag = array.new_float(0)"). each zigzag points contains 2 element: 1. price level of the zz point 2. bar_index of the zz point oldzigzag : is the float array for the zigzag, you get copy the zigzag array to oldzigzag by "oldzigzag = array.copy(zigzay)" before calling get_zigzag() function dir : is the direction of the zigzag wave upcol : is the color of the line if zigzag direction is up dncol : is the color of the line if zigzag direction is down Returns: null
