I wrote a strategy that includes trailing profit by following examples of another coders. However, when the entry conditions are still valid and the strategy entry executed second time, it still takes the previous position's trailing profit price. it causes multiple entries and exits without any profit (in fact trailing offset works, so profit is random when the prices are still going up).
I tried many things such as barssince or strategy position commands to distinguish from previous entry. But I failed.
Sorry about my code seems like a mass. My problem is specificly starts the startLongDeal and longIsActive variables after line 112. You can see that desired exit prices are plotted in the code.
Thank you in advance!
