Code for partial close with percentage

  I’m using the following partial close with a EUR/USD mini strategy:

  ONCE partialclose = 1 IF partialclose THEN ONCE PerCent = 0.9 //% positions to close ONCE PerCent2 = 0.01 //% positions to close ONCE MinLotSize = 1 //1 lots minimum ExitQuantity = abs(CountOfPosition) * PerCent LeftQty = max(MinLotSize,abs(CountOfPosition) - ExitQuantity) CloseQuantity = abs(CountOfPosition) - LeftQty ExitQuantity2 = abs(CountOfPosition) * PerCent2 LeftQty2 = max(MinLotSize,abs(CountOfPosition) - ExitQuantity2) CloseQuantity2 = abs(CountOfPosition) - LeftQty2 IF Not OnMarket THEN Flag = 1 Flag2 = 1 ENDIF IF LongOnMarket and close >= (PositionPrice + 4*pipsize) AND Flag THEN SELL CloseQuantity Contracts AT Market Flag = 0 endif IF ShortOnMarket and close <= (PositionPrice - 8*pipsize) AND Flag2 THEN exitshort CloseQuantity2 Contracts AT Market Flag2 = 0 endif 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

  ONCE partialclose = 1 IF partialclose THEN ONCE PerCent     = 0.9              //%  positions to close ONCE PerCent2     = 0.01              //%  positions to close ONCE MinLotSize  = 1              //1  lots minimum ExitQuantity     = abs(CountOfPosition) * PerCent LeftQty          = max(MinLotSize,abs(CountOfPosition) - ExitQuantity) CloseQuantity    = abs(CountOfPosition) - LeftQty   ExitQuantity2     = abs(CountOfPosition) * PerCent2 LeftQty2          = max(MinLotSize,abs(CountOfPosition) - ExitQuantity2) CloseQuantity2    = abs(CountOfPosition) - LeftQty2 IF Not OnMarket THEN Flag = 1 Flag2 = 1 ENDIF IF LongOnMarket and close >= (PositionPrice + 4*pipsize)  AND Flag THEN SELL CloseQuantity Contracts AT Market Flag = 0 endif   IF ShortOnMarket and close <= (PositionPrice - 8*pipsize)  AND Flag2 THEN exitshort CloseQuantity2 Contracts AT Market Flag2 = 0 endif endif

  This seems to work and the result is better than without partial close, but I’m getting confused between % and pips, especially as the optimization is so different for long and short (0.9 vs 0.01) ???

  The profit target is 0.9% long and 0.5% short. If 0.9% is ~110 pips, how does 4*pipsize relate to that?

  I tried using

  IF LongOnMarket and close >= (PositionPrice * (1 + PerCentGain))

  1	IF LongOnMarket and close >= (PositionPrice * (1 + PerCentGain))

  but it definitely works better with pipsize.

  To put some detail on this, I find it hard to make sense of the partial closes in the attached order list.

  On 19 Apr it buys 10 @ 1.19606 and sells 90% after a gain of .00067

  On 29 Mar it buys 10 @ 1.17864 and sells 90% after a gain of .00109, which is a huge difference.

  Is this just a matter of slippage? in which case, what should the partial close amount be, in pips?

  Most grateful for any enlightenment…
