I've been running strategies on Streak for a while now and one thing genuinely frustrates me.
After every failed backtest, the platform shows me: - Win rate: 43% - Max drawdown: 31% - Sharpe ratio: 0.4
But it never tells me WHY it failed.
Was it because February and March were strongly trending and my RSI strategy only works in sideways markets? Was it because my stop loss was too tight for the volatility that month? Was it because I overtested and the edge was never real to begin with?
I genuinely can't tell. I end up just tweaking parameters and running the backtest again — which I know is wrong but I don't know what else to do.
How do you all approach this? Do you manually go through the trade log? Do you look at market conditions during the losing period? Is there a systematic way to diagnose a failed strategy that I'm missing?
Would love to hear how experienced traders here actually approach this problem.
