You right, I do not have an explanation. The person who sold me the EA explained me how to set the EA, but trades open without SL and the system usually set a TP and only a SL at Breakeven.
I am asking since friday to give me the same settings as the system he showed, but he is not answering to me.
He disappeared. The system you see is very dangerous, with trades open for days without a SL, even if they are only the 1% of the account.
I tried to optimise the SL but I did not succeed.
I just noticed that he has got only one trade per day, with SL and TP, very different from the EA he sold to me.
