did you ask him about his "system" drawdowns, losing/winning streak, profit factor. period tested. i guess not. you should never buy any "systems". I doubt you are profitable. And if someone had winning system, he would keep it to himself
Just looking at weekly data 2018 was not profitable lost 213 ES points, 2019 so far made 92 points using 1 lot. looks like works better with smaller weekly ranges. I will backtest it but any suggestions as far as stops? low of opex week? fixed stop? test with ES or SPY? anything else? this...
