If you're six months into a drawdown right now and second-guessing every rule, that's the part the research can't simulate.
I've sat where you're sitting.
I had the Monte Carlo open in another spreadsheet. I knew the actual drawdown was within spec.
None of that made watching the equity curve any easier.
Most of us tweak something at that point. The few who don't are the ones whose strategies survive the recovery and prove the research right.
Trust the process.
