In my opinion, successful trading is 20% mechanics, 80% in your head. Anyone can find a successful strategy.
Backtest, backtest, backtest for 90 days or 100 trades.
Add to your trading plan these questions; how did I feel before, during and after the trade?
Have you ever committed to a strategy for 90 solid days? Many haven’t. Many cannot.
I also believe any trading plan needs to be tweaked. You’re in charge of that of course. I would never in a million years ever… stop learning. You are always in charge of what you learn.
Hope some of that helps,
