DivergenceLibrary "Divergence"
Calculates a divergence between 2 series
bullish(_src, _low, depth) Calculates bullish divergence
Parameters:
_src : Main series
_low : Comparison series (`low` is used if no argument is supplied)
depth : Fractal Depth (`2` is used if no argument is supplied)
Returns: 2 boolean values for regular and hidden divergence
bearish(_src, _high, depth) Calculates bearish divergence
Parameters:
_src : Main series
_high : Comparison series (`high` is used if no argument is supplied)
depth : Fractal Depth (`2` is used if no argument is supplied)
Returns: 2 boolean values for regular and hidden divergence
I created this library to plug and play divergences in any code.
You can create a divergence indicator from any series you like.
Fractals are used to pinpoint the edge of the series. The higher the depth, the slower the divergence updates get.
My Plain Stochastic Divergence uses the same calculation. Watch it in action.

DrawIndicatorOnTheChartLibrary "DrawIndicatorOnTheChart"
this library is used to show an indicator (such RSI, CCI, MOM etc) on the main chart with indicator's horizontal lines in a window. Location of the window is calculated dynamically by last price movemements
drawIndicator(indicatorName, indicator, indicatorcolor, period, indimax_, indimin_, levels, precision, xlocation) draws the related indicator on the chart
Parameters:
indicatorName : is the indicator name as string such "RSI", "CCI" etc
indicator : is the indicator you want to show, such rsi(close, 14), mom(close, 10) etc
indicatorcolor : is the color of indicator line
period : is the length of the window to show
indimax_ : is the maximum value of the indicator, for example for RSI it's 100.0, if the indicator (such CCI, MOM etc) doesn't have maximum value then use "na"
indimin_ : is the minimum value of the indicator, for example for RSI it's 0.0, if the indicator (such CCI, MOM etc)doesn't have maximum value then use "na"
levels : is the levels of the array for the horizontal lines. for example if you want horizontal lines at 30.0, and 70.0 then use array.from(30.0, 70.0). if no horizontal lines then use array.from(na)
precision : is the precision/number of decimals that is used to show indicator values, for example for RSI set it 2
xlocation : is end location of the indicator window, for example if xlocation = 0 window is created on the index of the last bar/candle
Returns: none
