OK, so this is more of a money management problem.
Or not holding winners long enough, which is common. You could try posting your trades. Sounds like you may have an edge, which you are giving up.
I think you might be right. One thing I noticed is that right after I close the trade it generally goes back to a profitable price. Another possible issue I see is that sometimes I don't close them early enough. I think I need a better rule as to when I should close my winners. I was reading how some people use the ATR for this purpose and it looks reasonable.
If I do a single contract and it goes to $100 I would usually hold and try to get to a bit more.
I tried TastyTrade strategies for a few months as well. You can have a high rate of profitable trades, but then there is always the one - trades that eat your profits. Also, the commissions are insane.
