I don't day trade or trade futures but it seems to me that your entrys are the problem.What's your personal exit strategy upon losing? Do you always stick to your original stop loss? Do you try to Martingale a few times before conceding defeat?
A problem I'm having coming up with a strategy is that my SL will get hit if I do the R:R anywhere close to 1:1 or even 2:1. Especially since I'm trying to be a scalper at this point. I would get stopped out of trades that I would have won if I just held out longer.
Try putting your entrys where your stops are.
