Hi, I was wondering if anyone can get this Percentile code to work: VolRank = Percentile[60](Volume, 75) // 75th percentile of past 60 bars I tried many iterations but i am not sure why it won’t work? Also what happened to the add code icon? Cheers!
// ============================================================

// Strategy: bearish_engulf_MA20_25pct

// Description: Short on bearish engulfing below MA20 with volume filter

// ============================================================

// — Parameters

DEFPARAM CumulateOrders = False

DEFPARAM PreLoadBars = 60

StopPercent = 2.0 // change to 1.0, 3.0, etc. as needed

Capital = 1000

// — Indicators

MA20 = Average[20](Close)

VolRank = Percentile[60](Volume, 75) // 75th percentile of past 60 bars

// — Bearish Engulfing detection

BearishEngulf = (Close[1] > Open[1]) AND (Close < Open) AND (Open > Close[1]) AND (Close < Open[1])

// — Entry condition

ShortCondition = BearishEngulf AND (Close < MA20) AND (Volume > VolRank)

// — Position management

If ShortCondition THEN

SellShort 1 CONTRACT AT MARKET

ENDIF

// — Stop-loss in price terms

If ShortOnMarket THEN

EntryPrice = ShortPrice

StopPrice = EntryPrice * (1 + StopPercent / 100)

SET STOP pLOSS (StopPercent * Capital / 100)

ENDIF

// — Exit end-of-day (if not stopped)

If ShortOnMarket AND BarIndex > TradeIndex THEN

ExitShort AT Close

ENDIF

If we press Ctrl + F5 (clear cache for PRC website only) before we start typing then you should see the blue ‘Insert PRT Code’ icon at the far right of the top toolbar? Trick is remembering to Ctrl + F5 BEFORE typing anything at all! If you Ctrl + F5 after typing then you lose whatever you just typed!

Hi, You use “Percentile[60](Volume,75)” as an indicator, but this indicator does not exist (by default) in PRT… You will first have to calculate the “Percentile” yourself…

Hi. Here you have an example of percentile calculation:
```
//Percentile
p=252
rnkCount = 0
count = 0
FOR i = 1 to p-1
count = count + 1
IF close[i] < close THEN
rnkCount = rnkCount + 1
endif
NEXT
 
PercentileRank = (rnkCount/count)*100

drawhline(10)style(dottedline)
drawhline(20)style(dottedline,2)
drawhline(30)style(dottedline)
drawhline(40)style(dottedline,2)
drawhline(50)style(dottedline1)coloured("red")
drawhline(60)style(dottedline,2)
drawhline(70)style(dottedline)
drawhline(80)style(dottedline,2)
drawhline(90)style(dottedline)
return PercentileRank
```
