    You say

    Analyze the trade logs in strategy_v4_backtest.csv. I tested about 12 different parameter sets before picking this one, and my broker charges 1.5 bps per round-trip.

    Your agent does

    Backtest Verdict: FAIL

    • Reason: Failed Multiple-Testing Correction (Sidak).
    • Edge Probability: 62% (below 95% threshold).
    • Break-even Cost: 0.8 bps.
    • Analysis: Your real cost (1.5 bps) exceeds the break-even. The 'best' variant you found is likely a result of luck among 12 trials.

    What you get

    Identify if a strategy's performance is statistically indistinguishable from luck.Calculate the maximum trade cost a strategy can handle before becoming unprofitable.Correct for cherry-picking bias when multiple strategy variants were tested.Determine if a trade log has a sufficient sample size for reliable deployment.

    About this skill

    Validates whether a trading strategy has a real, tradeable edge by running the four checks most backtests skip: sample-size/power, realistic costs with break-even, luck (10k bootstrap), and multiple-testing (Sidak + PSR). Feed it a trades CSV; get a verdict plus the break-even cost, the level where the edge dies. For traders tired of strategies that look great and lose live.
