Condition met, Buy below certain price in the future bars

  Hi

  I am trying to code in PRT and when backtesting it is not giving the desired results, as it is NOT buying at the TargetPrice, seems I am not getting it right.

  Attached screenshot for reference, where the condition met at Bar 1583 with my TargetPrice to buy at 14737.2, but it is bought at Bar 1585 at a price 14816.5.

  My TargetPrice and CloseReferencePrice are also changing for each bar, and BuyBar and CurrentBar are also the same when the code runs for backtesting.

  Could please advise how this should be done i.e. Buying at the TargetPrice within the next 5 bars when the C1 condition is met,  with the below script:

  But at TargetPrice based on CloseReferencePrice

  // Definition of code parameters DEFPARAM CumulateOrders = False // Cumulating positions deactivated TIMEFRAME(4 hours) // Variables to store the reference price and flag ReferencePrice = 0.0 BuyFlag = 0 TargetPrice = 0.0 buybar = 0 // Conditions to enter long positions indicator1 = Stochastic[10,5](close) c1 = (indicator1 <= 10) // Check if the indicator condition (c1) is met and set the reference price if c1 and BuyFlag=0 then //and IsLastBarUpdate=1 then ReferencePrice = close BuyFlag = 1 buybar = barindex endif // Calculate the TargetPrice based on the reference price (outside the bar) if BuyFlag=1 then TargetPrice = ReferencePrice - (20*POINTSIZE) endif // Check if the close price is less than or equal to the TargetPrice if BuyFlag=1 and barindex-buybar<=5 then BUY 1 CONTRACT AT TargetPrice LIMIT endif // Conditions to exit long positions indicator2 = Average[3](Stochastic[10,5](close)) c2 = (indicator2 >= 90) IF c2 THEN SELL AT MARKET ENDIF // Stops and targets //SET STOP pLOSS 20 //SET TARGET pPROFIT 40 graph TargetPrice as "TargetPrice" graph ReferencePrice as "CloseRefPrice" graph buybar as "BuyBar" graph barindex as "CurrentBarIndex" graph BuyFlag as "BuyFlag"

  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 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47

  // Definition of code parameters DEFPARAM CumulateOrders = False // Cumulating positions deactivated TIMEFRAME(4 hours)   // Variables to store the reference price and flag ReferencePrice = 0.0 BuyFlag = 0 TargetPrice = 0.0 buybar = 0   // Conditions to enter long positions indicator1 = Stochastic[10,5](close) c1 = (indicator1 <= 10)   // Check if the indicator condition (c1) is met and set the reference price if c1 and BuyFlag=0 then //and IsLastBarUpdate=1 then ReferencePrice = close BuyFlag = 1 buybar = barindex endif   // Calculate the TargetPrice based on the reference price (outside the bar) if BuyFlag=1 then TargetPrice = ReferencePrice - (20*POINTSIZE) endif   // Check if the close price is less than or equal to the TargetPrice if BuyFlag=1 and barindex-buybar<=5 then BUY 1 CONTRACT AT TargetPrice LIMIT endif   // Conditions to exit long positions indicator2 = Average[3](Stochastic[10,5](close)) c2 = (indicator2 >= 90)   IF c2 THEN SELL AT MARKET ENDIF   // Stops and targets //SET STOP pLOSS 20 //SET TARGET pPROFIT 40 graph TargetPrice as "TargetPrice" graph ReferencePrice as "CloseRefPrice" graph buybar as "BuyBar" graph barindex as "CurrentBarIndex" graph BuyFlag as "BuyFlag"

  Thanks

  Hi Harry,

  It goes wrong by “resetting” the variables every time the code is executed…

  Use “Once” here and reset the variable “BuyFlag” when you are actually in a “Long” position…

   

  Buy at TargetPrice

  // Definition of code parameters DEFPARAM CumulateOrders = False // Cumulating positions deactivated TIMEFRAME(4 hours) // Variables to store the reference price and flag Once ReferencePrice = 0.0 Once BuyFlag = 0 Once TargetPrice = 0.0 Once buybar = 0 // Conditions to enter long positions indicator1 = Stochastic[10,5](close) c1 = (indicator1 <= 10) // Check if the indicator condition (c1) is met and set the reference price if c1 and BuyFlag=0 then //and IsLastBarUpdate=1 then ReferencePrice = close BuyFlag = 1 buybar = barindex endif // Calculate the TargetPrice based on the reference price (outside the bar) if BuyFlag=1 then TargetPrice = ReferencePrice - (20*POINTSIZE) endif // Check if the close price is less than or equal to the TargetPrice if BuyFlag=1 and barindex-buybar<=5 then BUY 1 CONTRACT AT TargetPrice LIMIT endif // Conditions to exit long positions indicator2 = Average[3](Stochastic[10,5](close)) c2 = (indicator2 >= 90) IF c2 THEN SELL AT MARKET BuyFlag=0 ENDIF // Stops and targets //SET STOP pLOSS 20 //SET TARGET pPROFIT 40 graph TargetPrice as "TargetPrice" graph ReferencePrice as "CloseRefPrice" graph buybar as "BuyBar" graph barindex as "CurrentBarIndex" graph BuyFlag as "BuyFlag"

  Hi JS

  Thanks for this insight, very much appreciated. I would have never got this right on my own without your help on this, it works now as expected.
