Most traders remember their best trades and forget the habits behind their worst ones. A trading journal fixes that by turning each trade into a record you can study. It is the cheapest and most useful tool in trading.
Why a journal works
You cannot improve what you do not measure. A journal shows which setups actually perform for you, when you break your own rules and how your emotions affect your decisions. Over a few months it replaces guesses with evidence.
What to record for every trade
- Date, instrument and direction (long or short)
- Entry price, stop-loss, target and exit price
- Quantity and the amount you risked
- Brokerage and charges, so your results are net, not gross
- The reason you took the trade and the reason you exited
- Your emotional state before and after
- Mistakes and lessons
The numbers worth tracking
- Win rate: the share of trades that made money
- Average risk-to-reward: average gain compared with average loss
- Net profit and loss: after all charges
- Largest drawdown: the deepest fall from a peak in your account
- R-multiple: each trade's result measured in units of the amount you risked
No single number tells the story. A low win rate can be fine with a high reward-to-risk, and a high win rate can hide a few very large losses.
Run a weekly review
Every weekend, spend thirty minutes with your journal and ask:
- Did I follow my rules on every trade?
- Which trades broke the rules and why?
- Which setup produced the best and worst results?
- What is the one thing I will do differently next week?
Common journaling mistakes
- Writing only when you win
- Leaving out small trades
- Skipping the emotion column
- Never reading the journal back
