Nic, Could you please convert the VIX Fix for PRT please? Link. Here is the Pine Script code: study(“CM_Williams_Vix_Fix”, overlay=false) pd = input(22, title=”LookBack Period Standard Deviation High”) bbl = input(20, title=”Bolinger Band Length”) mult = input(2.0 , minval=1, maxval=5, title=”Bollinger Band Standard Devaition Up”) lb = input(50 , title=”Look Back Period Percentile High”) ph = input(.85, title=”Highest Percentile – 0.90=90%, 0.95=95%, 0.99=99%”) pl = input(1.01, title=”Lowest Percentile – 1.10=90%, 1.05=95%, 1.01=99%”) hp = input(false, title=”Show High Range – Based on Percentile and LookBack Period?”) sd = input(false, title=”Show Standard Deviation Line?”) wvf = ((highest(close, pd)-low)/(highest(close, pd)))*100 sDev = mult * stdev(wvf, bbl) midLine = sma(wvf, bbl) lowerBand = midLine – sDev upperBand = midLine + sDev rangeHigh = (highest(wvf, lb)) * ph rangeLow = (lowest(wvf, lb)) * pl col = wvf >= upperBand or wvf >= rangeHigh ? lime : gray plot(hp and rangeHigh ? rangeHigh : na, title=”Range High Percentile”, style=line, linewidth=4, color=orange) plot(hp and rangeLow ? rangeLow : na, title=”Range High Percentile”, style=line, linewidth=4, color=orange) plot(wvf, title=”Williams Vix Fix”, style=histogram, linewidth = 4, color=col) plot(sd and upperBand ? upperBand : na, title=”Upper Band”, style=line, linewidth = 3, color=aqua)
