How to Use Backtesting
Backtesting is only useful when assumptions are clear. Learn how to structure tests, compare variants, and avoid misleading results.
Start with a testable hypothesis
Backtesting works best when the strategy rules are explicit. If the setup depends on discretionary context that cannot be described clearly, the test will be hard to trust.
A disciplined setup flow
- Define the market, timeframe, and entry condition.
- Specify exits, stop placement, and sizing logic.
- Test one meaningful change at a time instead of many at once.
- Review drawdowns and trade distribution, not just headline return.
A strategy with strong average returns can still be operationally untradeable if the drawdowns, holding periods, or win-rate profile do not fit your style.
Keep the limits in view
Backtests are simplified models. Slippage, liquidity, regime shifts, and data quality all affect how much confidence you should place in the output.
If a strategy only works after many tiny parameter tweaks, it may be fitting noise rather than discovering durable edge.
