  • breakeven_cost_finder

    Compute the exact per-trade cost (commission + slippage combined, in dollars) at which this strategy's net P&L hits exactly zero. A single concrete number: "this edge survives up to $X of combined friction per trade" — compare it directly against real expected costs for the instrument/broker rather than eyeballing a sweep table.

  • cost_sensitivity_sweep

    Recompute net P&L, win rate, and profit factor across a range of assumed per-trade transaction costs (commission + slippage combined, in dollars per round-turn trade). Backtests commonly use unrealistically cheap or zero-cost fills — this shows exactly how fast the reported edge degrades as realistic friction is added, and at what cost level it flips negative.

  • lookahead_bias_checklist

    Structured look-ahead-bias audit for a backtest — answer what your actual backtest does for each question, get back which specific, well-known leakage patterns you're exposed to. Covers the sources that pass a compile/run cleanly and still quietly inflate results: same-bar high/low entry logic, indicators computed from an unclosed bar, position sizing off future volatility, survivorship-filtered universes, and un-timed price adjustments.
