Conversion Indic Predictive Ranges from TV to PRT

Hello to the PRT masters, Would you be so kind to adapt the following TradingView code into a PRT code ? indicator(“Predictive Ranges [LuxAlgo]”, “LuxAlgo – Predictive Ranges”, overlay = true) //—————————————————————————— //Settings //—————————————————————————–{ length = input.int(200, ‘Length’, minval = 2) mult = input.float(6., ‘Factor’, minval = 0, step = .5) tf = input.timeframe(”, ‘Timeframe’) src = input(close, ‘Source’) //—————————————————————————–} //Function //—————————————————————————–{ pred_ranges(length, mult)=> var avg = src var hold_atr = 0. atr = nz(ta.atr(length)) * mult avg:=src-avg>atr?avg+atr: avg-src>atr?avg-atr: avg hold_atr := avg != avg[1] ? atr / 2 : hold_atr [avg + hold_atr * 2, avg + hold_atr, avg, avg – hold_atr, avg – hold_atr * 2] //—————————————————————————–} //Calculation //—————————————————————————–{ [prR2 , prR1 , avg , prS1 , prS2] = request.security(syminfo.tickerid, tf, pred_ranges(length, mult)) //—————————————————————————–} //Plots //—————————————————————————–{ plot_pru2 = plot(prR2, ‘PR Upper 2’, avg != avg[1] ? na : #f23645) plot_pru1 = plot(prR1, ‘PR Upper 1’, avg != avg[1] ? na : #f23645) plot_pravg = plot(avg , ‘PR Average’, avg != avg[1] ? na : #5b9cf6) plot_prl1 = plot(prS1, ‘PR Lower 1’, avg != avg[1] ? na : #089981) plot_prl2 = plot(prS2, ‘PR Lower 2’, avg != avg[1] ? na : #089981) //Fills fill(plot_pru2, plot_pru1, avg != avg[1] ? na : color.new(#f23645, 95)) fill(plot_prl1, plot_prl2, avg != avg[1] ? na : color.new(#089981, 95)) //—————————————————————————–} Thanks in advance, Reb

Hello to the PRT masters,

Would you be so kind to adapt the following TradingView code into a PRT code ?

indicator(“Predictive Ranges [LuxAlgo]”, “LuxAlgo – Predictive Ranges”, overlay = true)

//——————————————————————————

//Settings

//—————————————————————————–{

length = input.int(200, ‘Length’, minval = 2)

mult = input.float(6., ‘Factor’, minval = 0, step = .5)

tf = input.timeframe(”, ‘Timeframe’)

src = input(close, ‘Source’)

//—————————————————————————–}

//Function

//—————————————————————————–{

pred_ranges(length, mult)=>

var avg = src

var hold_atr = 0.

atr = nz(ta.atr(length)) * mult

avg:=src-avg>atr?avg+atr:

avg-src>atr?avg-atr:

avg

hold_atr := avg != avg[1] ? atr / 2 : hold_atr

[avg + hold_atr * 2, avg + hold_atr, avg, avg – hold_atr, avg – hold_atr * 2]

//—————————————————————————–}

//Calculation

//—————————————————————————–{

[prR2

, prR1

, avg

, prS1

, prS2] = request.security(syminfo.tickerid, tf, pred_ranges(length, mult))

//—————————————————————————–}

//Plots

//—————————————————————————–{

plot_pru2 = plot(prR2, ‘PR Upper 2’, avg != avg[1] ? na : #f23645)

plot_pru1 = plot(prR1, ‘PR Upper 1’, avg != avg[1] ? na : #f23645)

plot_pravg = plot(avg , ‘PR Average’, avg != avg[1] ? na : #5b9cf6)

plot_prl1 = plot(prS1, ‘PR Lower 1’, avg != avg[1] ? na : #089981)

plot_prl2 = plot(prS2, ‘PR Lower 2’, avg != avg[1] ? na : #089981)

//Fills

fill(plot_pru2, plot_pru1, avg != avg[1] ? na : color.new(#f23645, 95))

fill(plot_prl1, plot_prl2, avg != avg[1] ? na : color.new(#089981, 95))

//—————————————————————————–}

Thanks in advance,

Reb

Hi. Here you have the code: https://www.prorealcode.com/prorealtime-indicators/predictive-ranges-indicator/

Hi Ivan

Well done, nice job

I have a discrepancy between range size in PRT and those in TV, do you know why ? (see attached)

Thks in advance

Hi. I don't know. It could be because the prices are not the same (dividend adjustment, due to the data source itself, …)
