Well so far it's worked over 12 trades barely. At the rate you're trading it has to work over 3000 trades and overcome fees.
I think you need help. I only know you for maybe 15 minutes and you come out as lonely to me. Most other people probably wouldn't care about my holy grail. Most successful traders definitely wouldn't care they already have their own.
Your holy grail is priceless. Don't be foolish to sell it. As long as you are alive, Use it to generate tons of money.
Since you passed the Topstep account 2 weeks ago I would say 2 weeks at this point in time. However 2 weeks can still be completely random, you can't expect anyone to take you seriously without a decent track record.
400 trades is a good basis to evaluate a strategy. Samples of 400 have a margin of error of less than around 1/20 at 95% confidence. But the more, the better.
