Is My Trading Strategy Overfit? How to Check | AlgoBars

Is your strategy overfit? How to check

The short answer

A strategy is overfit when it was tuned so closely to past data that it learned noise, not an edge. Warning signs are many parameters, very few trades, and results that collapse when settings change slightly. Check it with walk-forward analysis on unseen data and Monte Carlo simulation of trade order, both on AlgoBars, and trust only settings that hold up.

  1. Walk-forward test on data the optimizer never saw.
  2. Run a Monte Carlo simulation to see the range of outcomes.
  3. Test nearby settings: robust strategies degrade gently.
  4. Check other markets and periods.
