Conversion of TradingView strategy to PRT Indicator and screener

  Hey there PRT team,

  I’m hoping for some assistance with converting the daily  High/Low strategy in Tradingview, to an indicator (with buy/sell signals) + screener for Pro Real Time. I’ve made a few attempts and failed miserably, so any assistance would be amazing!

  Hi @iamboston

  The basis of the system is:

  High > DHigh(1)

  Low < DLow(1) Furthermore, it is examined whether: Close > EMA[24](Close) for LONG

  Close < EMA[24](Close) for SHORT An additional indicator is used to confirm: Chaikin Money Flow (CMF) CMF > 0 for LONG

  CMF < 0 for SHORT The exit of the trades is done with: Close Crosses Under EMA[24](Close) (Sell) Close Crosses About EMA[24](Close) (ExitShort)

  Daily High/Low Strategy

  DefParam CumulateOrders=False EMAPeriod=24 //Period of EMA S1=ExponentialAverage[EMAPeriod](Close) //EMA signal CMFPeriod=20 //Period of Chaikin Money Flow MFM = ((Close-Low)-(High-Close)) / (High-Low) //Money Flow Multiplier MFV = MFM * Volume //Money Flow Volume CMF = Summation[CMFPeriod](MFV) / Summation[CMFPeriod-1](Volume) //Chaikin Money Flow //LONG If High Crosses Over DHigh(1) and Close > S1 and CMF > 0 then Buy 1 contract at Market EndIf //Exit LONG If Close Crosses Under S1 then Sell at Market EndIf //SHORT If Low Crosses Under DLow(1) and Close < S1 and CMF < 0 then SellShort 1 contract at Market EndIf //Exit SHORT If Close Crosses Over S1 then ExitShort at Market EndIf

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

  DefParam CumulateOrders=False   EMAPeriod=24 //Period of EMA S1=ExponentialAverage[EMAPeriod](Close) //EMA signal   CMFPeriod=20 //Period of Chaikin Money Flow MFM = ((Close-Low)-(High-Close)) / (High-Low) //Money Flow Multiplier MFV = MFM * Volume //Money Flow Volume CMF = Summation[CMFPeriod](MFV) / Summation[CMFPeriod-1](Volume) //Chaikin Money Flow   //LONG If High Crosses Over DHigh(1) and Close > S1 and CMF > 0 then Buy 1 contract at Market EndIf //Exit LONG If Close Crosses Under S1 then Sell at Market EndIf   //SHORT If Low Crosses Under DLow(1) and Close < S1 and CMF < 0 then SellShort 1 contract at Market EndIf //Exit SHORT If Close Crosses Over S1 then ExitShort at Market EndIf

  I’m surprised. For a breakout system it works quite well. At least long, also on Nasdaq or SP500. But then with EMA45. Short would also work, but then with a different exit strategy. The long candles, which should cause the exit in short mode, are usually simply too long in the time unit. Short would need another exit.

  Agreed, I use it manually with a discretionary exit.

  Hi there JS,

  Hope you had a great weekend. Would it be possible to have the indicator that you created for the system, too? From there I’ll have a go at creating a screener, too.

  Hope all’s well and thank you again!

  Hi @iamboston

  It is a simple indicator, for the CMF you can use the standard indicator from PRT…

   

  Daily High/Low Indicator
