Trailing stoploss problems

  Hi there,

  I’ve been tinkering on this bit of code for several days and cannot figure out how to eliminate several behaviors:

  1. It sometimes places a negative stoploss. It should only start to place a stoploss when the position is breakeven yet at times it will place a stoploss at a loss…
  2. It sometimes does, sometimes does not increase the trailing stoploss. Obviously, it should always increase whenever possible

  If not onmarket then sellshort 1 contract at market endif minsteps = 5 shortbreakeven = positionprice - minsteps Fullshortexit = positionprice - 10 If shortonmarket and Close[1] > shortbreakeven and Close <= shortbreakeven then ShortStopSignal = 1 Elsif not shortonmarket then ShortStopSignal = 0 Endif If ShortStopSignal[1] = 0 and ShortStopSignal = 1 then ShortProfitTime = BarIndex elsif not shortonmarket then ShortProfitTime = 0 Endif // Short Profit Stoploss management : If ShortProfitTime <> 0 and close > Fullshortexit and close < positionprice then ShortStopProfit = PositionPrice - 1 Elsif ShortProfitTime <> 0 and close <= Fullshortexit and abs(Close - PositionPrice)/MinSteps < 4 then ShortStopProfit = Close + MinSteps Elsif ShortProfitTime <> 0 and close <= Fullshortexit and abs(Close - PositionPrice)/MinSteps >= 4 then ShortStopProfit = close + 2*MinSteps elsif ShortProfitTime = 0 then ShortStopProfit = 0 Endif If ShortProfitTime <> 0 then MyShortStopProfit = lowest[Max(1,BarIndex - ShortProfitTime)](ShortStopProfit) Endif if onmarket then sell at MyshortStopProfit stop 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 28 29 30 31 32 33 34 35 36 37 38

  If not onmarket then sellshort 1 contract at market endif   minsteps = 5 shortbreakeven = positionprice - minsteps Fullshortexit = positionprice - 10   If shortonmarket and Close[1] > shortbreakeven and Close <= shortbreakeven then ShortStopSignal = 1 Elsif not shortonmarket then ShortStopSignal = 0 Endif   If ShortStopSignal[1] = 0 and ShortStopSignal = 1 then ShortProfitTime = BarIndex elsif not shortonmarket then ShortProfitTime = 0 Endif   // Short Profit Stoploss management : If ShortProfitTime <> 0 and close > Fullshortexit and close < positionprice then ShortStopProfit = PositionPrice - 1 Elsif ShortProfitTime <> 0 and close <= Fullshortexit and abs(Close - PositionPrice)/MinSteps < 4 then ShortStopProfit = Close + MinSteps Elsif ShortProfitTime <> 0 and close <= Fullshortexit and abs(Close - PositionPrice)/MinSteps >= 4 then ShortStopProfit = close + 2*MinSteps elsif ShortProfitTime = 0 then ShortStopProfit = 0 Endif   If ShortProfitTime <> 0 then MyShortStopProfit = lowest[Max(1,BarIndex - ShortProfitTime)](ShortStopProfit) Endif   if onmarket then sell at MyshortStopProfit stop endif

  Thanks for the help, I’m really confused about what it is I’m not getting…

  I have submitted your problem to I.A, hereinafter the answer:

  Incorrect calculations: Calculations for shortbreakeven, Fullshortexitet stop-loss conditions seem to correspond to arbitrary price levels ( minsteps, positionprice). These values should be based on the actual performance of the position.

  Initializing Variables: There is no ShortStopProfit, which can cause problems.

  Fuzzy logic: The logic to determine when to place a stop-loss or increase it seems complex and possibly subject to

  Exit conditions:

  Using BarIndex: Using BarIndexpor to measure profit time can be prone to errors as it depends on the number of bars you have loaded and the frequency of your data.

  Management of Short Positions: The code seems mainly intended for the management of short positions. Make sure this fits your trading strategy.

  To correct these problems, it may be necessary to rethink the logic of position management and adapt the

  Hi,

  To check if your logic is correct, use:

  GraphOnPrice ShortBreakEven

  GraphOnPrice FullShortExit

  GraphOnPrice PositionPrice

  Graph ShortStopSignal

  Etc.
