Paper Trading Coach: AI Review of Your Execution

Why AI Review Adds Value to a Trading Journal

Keeping a trading journal is common advice; actually reviewing one is rare. The friction is that patterns in execution — chasing, revenge trading, under-sizing winners, over-sizing losers — are hard to see in a spreadsheet of fills. A coach who looks at hundreds of your trades and summarizes the tendencies closes that gap. Done with a modern LLM pipeline anchored on actual fill data (not user-reported feelings), AI coaching is cheap, private, and surprisingly pointed.

What the Coach Card Shows

The Paper Trading Coach card reads your full paper order history and produces a structured review: hit rate by setup type, average winner vs average loser, expectancy per trade, time-of-day performance, and a plain-English critique of execution patterns. A per-trade drill-down lets you ask follow-up questions in natural language — "why did I lose on NVDA 2026-04-03?" — and the Coach will reference the specific fills, prior tape context, and any violations of your stated rules. The Coach also flags a short list of "highest-leverage changes" ranked by estimated P&L impact.

Using the Coach Productively

Three practices get the real value. First, set explicit trading rules and paste them into the Coach's rule-set at session start — "max 2% per trade, no trades in first 30min, stop-losses mandatory at entry"; the Coach then audits you against your own rules, not a generic template. Second, read the critique before looking at the P&L — the process feedback is more valuable than the outcome feedback; good process with bad outcomes is fine, bad process with good outcomes will catch up to you. Third, take one recommendation per week, not ten — picking the single highest-leverage change and actually implementing it beats reading ten and changing nothing.

Where It Fits

The Coach sits downstream of Account Summary, Order History, and your actual Positions — it reads all of them. For the AI analysis surface on live portfolios, see AI Insights.
