Trading Edge

Trading EdgeTest the Rule Before You Trade It


A trading signal is only useful after it survives the parts most backtests avoid.
We test technical rules against data-snooping, transaction costs, taxes, and out-of-sample evidence.

The Survival Test

How We Test a Claimed Trading Edge

A profitable chart in hindsight is not enough. The analysis has to show that the rule was defined before the result, survives realistic execution costs, and continues to work outside the sample that produced it.

01 · Signal

Was the rule defined clearly?

We separate testable entry and exit rules from visual pattern recognition that changes after the chart is already known.

02 · Friction

Does the edge survive implementation?

Turnover, spreads, slippage, taxes, and missed market exposure are included before a gross backtest is called investable.

03 · Survival

Does it work beyond the original sample?

We look for multiple-testing corrections, regime robustness, and out-of-sample evidence rather than rewarding one attractive historical period.

Backtest analysis for education and further research, not a recommendation to trade any signal or security.
