Percentile Code Error

  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

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

  //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
