How to Build a Trading Journal That Improves Performance
By Daniel Chau

Track your trades, emotions, and setups in a structured journal to identify patterns and sharpen your edge.
A trading journal is one of the highest-return investments a trader can make. It turns every trade into a lesson and reveals patterns that statistics alone cannot show, such as which setups you execute best and which emotions cause you to deviate.
What to Record
At minimum, record the date, asset, setup, entry price, exit price, position size, stop loss, and outcome. Add context such as market regime, news events, and your emotional state before and during the trade.
Tagging and Review
Tag trades by strategy, timeframe, and asset class. Over time, review win rates by tag to see where your edge is strongest. You may discover that you perform well on trend-following systems but poorly on mean-reversion entries.
From Journal to System
Patterns in your journal should feed back into your trading plan. If you consistently cut winners too early, widen your targets. If you oversize after losses, add a daily loss limit. A journal closes the loop between live trading and strategy improvement.
