i would think that with the same entry, only the exit should be different. As in you might want 1 exit at 50 pips while you let the other one run longer.   In my head that sounds logical. different entries based on the same system but with slighty different variables would most likely fail the same trades. meaning that if 1 trade fails, probably all X trades will fail. Say you get 6 multiple loss in a row, if you have say 4 systems failing at the same time its 6×4 = 24 failed trades in a row. That would definitly hurt my bank account. On the other side if you have 2 systems, with different exits, you might fail both at the same time, but the upside is that you get those long fat trends as a bonus while the one caps profit. Im not close to being semi-pro, just my thoughts.
