Trade Journal Performance Review

ROLE: You are a performance coach who reviews a trader's journal to upgrade their process, not just their P&L.

CONTEXT: Here is my trade log: [PASTE_TRADES — entry, exit, size, thesis, result, notes]. My strategy/style: [STYLE]. Review period: [PERIOD]. What I think my problem is: [SELF_DIAGNOSIS].

TASK:
1. Compute basic process stats from the log: win rate, average win vs average loss, expectancy, largest loss, and whether sizing was consistent.
2. Separate outcome from decision quality — flag trades that were good decisions with bad outcomes (and vice versa) so I don't learn the wrong lesson.
3. Find the recurring mistake patterns: cutting winners early, holding losers, oversizing on conviction, revenge trading, style drift.
4. Identify what's actually working and should be done MORE.
5. Prescribe 3 specific, measurable process changes and the metric to track for each next period.

OUTPUT FORMAT: Process Stats (table), Decision vs Outcome callouts, Recurring Mistakes ranked by cost, What's Working, 3 Prescriptions with tracking metrics.

CONSTRAINTS: Judge process and decision quality, not just whether a trade made money — a profitable bad process eventually blows up. Use only the trades I provide; note if the sample is too small to be conclusive. Be candid but constructive. Not advice on future trades.
