For what its worth - may I highly recommend you get some training on trader psychology before you go live. I dont want to play Dr. Psychologist here but this is a fact:
our brain is programmed to feel the pain of financial loss acutely, so that it has a better chance of avoiding loss the next time, e.g., your next trade, or even the next day or week. Its subconscious so merely telling yourself different will be futile. You need to address this because futures trading is much different than stock trading. Its a shark tank - for somebody to win, someone has to lose. Pro's know exactly where retail traders (you & me) trade and place stops. Your edge needs to be able to identify this so you are not 'the herd of sheep' that get sniped by the pros; otherwise your acct will be dismantled one trade at a time. Your methodology of course needs to suit you well and you need to know it well but that is 1/3 of the game.
I trade about 80% on sim - live feed, not replay or fixed anything. Yea fills come quicker because its a fake acct. But other than that, its as close to real as you can get.
I trade about 65-70% on live and still have alot of experience to gain in the area of mindset. That is exactly what is keeping me from that 80ish percentile of profitability in my live acct.
