How this service works
Reads your whole trade history and answers with exact laws, not a market forecast: is your edge proven (bootstrap, probabilistic Sharpe ratio, trades still needed), does your position size make you lose despite an edge (Kelly, volatility drag), did your edge die and when (CUSUM change detection), wh
Output
Returns a structured audit report including: bootstrap-based edge probability, probabilistic Sharpe ratio with confidence intervals, minimum trade count needed for statistical significance, Kelly criterion optimal fraction, volatility drag impact on returns, CUSUM change-point date and significance (when edge degraded or died), and if challenge rules are provided, a pass/fail assessment with margin analysis against each challenge constraint.
Example use cases
Prop firm challenge compliance check
“I'm in phase 1 of a funded challenge with a 10% profit target, 5% max daily loss, and 8% max total loss over 30 days. Here are my 120 trades so far. Am I statistically on track to pass, and is my current risk per trade of 0.8% sizing me correctly to hit the target without blowing the drawdown rules?”
Detecting when a strategy stopped working
“My trading strategy felt great for the first 6 months but returns have been awful lately. I have 450 trades with open and close times — can you run CUSUM change detection on them and tell me exactly when my edge died and whether what I'm seeing now is statistically different from before?”
Validating edge before scaling capital
“I have 180 trades with PnL and risk data from my mean-reversion strategy. Before I scale up to a $100k account, tell me if my edge is genuinely proven via bootstrap and probabilistic Sharpe ratio, how many more trades I'd need if it's not confirmed yet, and what Kelly fraction I should be using given my 20% max drawdown limit.”
Technical details
Endpoint
POSThttps://verdict.kechlab.com/v1/trade-audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need rigorous, law-based statistical verdicts about trading performance rather than narrative commentary or market forecasts. It is specifically suited for: validating whether a strategy's edge is real before scaling capital, diagnosing whether over-sizing is causing returns to underperform expectancy, pinpointing when a strategy regime-changed using CUSUM, or checking funded account challenge feasibility. Prefer it over generic analytics when you need bootstrap-corrected Sharpe ratios, Kelly-based sizing guidance, and change-point detection in a single auditable call.
Side effects
- Fewer than 10 trades supplied — minimum threshold not met, returns validation error
- Missing required pnl or r field on trade objects — returns schema error indicating which trades are malformed
- Contradictory challenge parameters (e.g. daily loss limit exceeding total loss limit) — may return undefined behavior or error
- Extremely high variance trade histories may produce wide confidence intervals making edge verdict inconclusive
- Network timeout on very large trade arrays near the 5000-trade limit
