Good.
I needed code for multiple partial closures within one operation.

If the operation is positive and earns equal to or more than 0.25%, close 1/5 of the position.
If the operation is positive and earns equal to or more than 0.5%, close 1/5 of the position.

It’s an example, thanks.

There you go (not tested):

If not OnMarket then
   Tally = 0
Endif
ProfitPC = PositionPrice * PositionPerf * 100
If ProfitPC >= 0.25 and Tally = 0 then
   Close PositionSize/5 contracts at Market
   Tally = Tally + 1
Endif
If ProfitPC >= 0.50 and Tally = 1 then
   Close PositionSize/5 contracts at Market
   Tally = Tally + 1
Endif

Here’s another version (also coded by Roberto👍)

ONCE partialclose = 1
ONCE PerCent     = pc              //0.2 = 20%  positions to close
ONCE PerCent2     = pc2            //0.2 = 20%  positions to close
ONCE PerCentGain = pcg             //.0025 = 0.25% gain
ONCE PerCentGain2 = pcg2            //.005 = 0.5% gain
ONCE MinLotSize  = 0.5              //0.5  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 partialclose AND LongOnMarket and close >= (PositionPrice * (1 + PerCentGain))  AND Flag THEN
SELL CloseQuantity Contracts AT Market
Flag = 0
endif
 
IF partialclose AND shortOnMarket and  close <= (PositionPrice * (1 - PerCentGain2)) AND Flag2 THEN
exitshort CloseQuantity2 Contracts AT Market
Flag2 = 0
endif

I’m sorry, but in Roberto’s code, line 5, it doesn’t matter if I put 0.25, 0.5, or 1, he always wins the same in backtest.

I think the code is not working properly.
