Provides function's indicators for pivot - trend - resistance.

pivots(src, lenght, isHigh) Detecting pivot points (and returning price + bar index.
Parameters:
src: The chart we analyse.
lenght: Used for the calcul.
isHigh: lookging for high if true, low otherwise.
Returns: The bar index and the price of the pivot.

calcDevThreshold(tresholdMultiplier, closePrice) Calculate deviation threshold for identifying major swings.
Parameters:
tresholdMultiplier: Usefull to equilibrate the calculate.
closePrice: Close price of the chart wanted.
Returns: The deviation threshold.

calcDev(basePrice, price) Custom function for calculating price deviation for validating large moves.
Parameters:
basePrice: The reference price.
price: The price tested.
Returns: The deviation.

pivotFoundWithLines(dev, isHigh, index, price, dev_threshold, isHighLast, pLast, iLast, lineLast) Detecting pivots that meet our deviation criteria.
Parameters:
dev: The deviation wanted.
isHigh: The type of pivot tested (high or low).
index: The Index of the pivot tested.
price: The chart price wanted.
dev_threshold: The deviation treshold.
isHighLast: The type of last pivot.
pLast: The pivot price last.
iLast: Index of the last pivot.
lineLast: The lst line.
Returns: The Line and bool is pivot High.

getDeviationPivots(thresholdMultiplier, depth, lineLast, isHighLast, iLast, pLast, deleteLines, closePrice, highPrice, lowPrice) Get pivot that meet our deviation criteria.
Parameters:
thresholdMultiplier: The treshold multiplier.
depth: The depth to calculate pivot.
lineLast: The last line.
isHighLast: The type of last pivot
iLast: Index of the last pivot.
pLast: The pivot price last.
deleteLines: If the line are draw or not.
closePrice: The chart close price.
highPrice: The chart high price.
lowPrice: The chart low price.
Returns: All pivot the informations.

getElIntArrayFromEnd() Get the last element of an int array.

isTrendContinuation(isTrendUp, arrayBounds, lastPrice, precision) Check if last price is between bounds array.
Parameters:
isTrendUp: Is actual trend up.
arrayBounds: The trend array.
lastPrice: The pivot Price that just be found.
precision: The percent we add to actual bounds to validate a move.
Returns: na if price is between bounds, true if continuation, false if not.

trendPricesIsHigh: The array trend is high.
interBarIndexes: The array inter bar index.
interPrices: The array inter price.
interPricesIsHigh: The array inter ishigh.
isTrendHesitate: The actual status of is trend hesitate.
isTrendUp: The actual status of is trend up.
trendPrecision: The var precision to add in "iscontinuation" function.
pLast: The last pivot price.
iLast: The last pivot bar index.
isHighLast: The last pivot "isHigh".
Returns: trend & inter arrays, is trend hesitate, is trend up.

drawBoundLines(startIndex, startPrice, endIndex, endPrice, breakingPivotIndex, breakingPivotPrice, isTrendUp) Draw bounds and breaking line of the trend.
Parameters:
startIndex: Index of the first bound line.
startPrice: Price of first bound line.
endIndex: Index of second bound line.
endPrice: price of second bound line.
breakingPivotIndex: The breaking line index.
breakingPivotPrice: The breaking line price.
isTrendUp: The actual status of the trend.
Returns: The lines bounds and breaking line.
