I cannot add targets to the system because
- Each target may hit a different time; so this makes our backtesting unreliable
- There may be cases where both target and stop loss may be hit; with end of day data we aren't sure which hit first
- Most of the time you are better off closing all the stocks at the end of the day but there were a few cases (including today) where exiting midday would give you better profits
This is something close to what you see is what you get system. If the differences are large, then there is something wrong with our strategy or execution.
Having said all this. you can provide a negative value to STOP_LOSS such as -2 to treat it as a profit but there would be no stop loss and we never know our max drawdown.
