Our angle
There is no mainstream, platform-agnostic 'Strategy Validator' that takes a user's trade log or basic logic and automatically runs a full suite of institutional-grade robustness tests (Ablation, Monte Carlo, Walk-Forward, Regime Purging).

Real quotes from Reddit comments that inspired this opportunity

  • I'm using MT5 for now, but you can do all that manually on any system.
  • Rather than splitting your data sets just into training, validation and holdout, I would recommend to do this by market regime as well.
