What a trading journal is
A trading journal is a structured record of every trade: entry and exit, size, the reason you took it, and the outcome. Over enough trades, it reveals patterns you can't see from any single position — which setups actually pay, which times of day you lose, and where fees quietly erode your returns.
The point isn't bookkeeping. It's converting a noisy stream of wins and losses into a small number of decisions you can change.
The metrics that actually matter
A handful of numbers do most of the work:
- Win rate: the share of trades that close in profit. Useful only alongside risk-to-reward.
- Risk-to-reward (R:R): your average win divided by your average loss. A 40% win rate is profitable at 2:1 R:R; a 60% win rate loses money at 1:3.
- Expectancy: the average rupee outcome per trade — the single best summary of whether your system makes money.
- Fees and funding: small per trade, large per month. Many active traders are surprised how much of their edge fees consume.
How to review it without fooling yourself
Review on a schedule, not after a bad day when you're emotional. Look for repeated mistakes, not one-off losses: revenge trades after a loss, oversized positions, exiting winners too early, holding losers too long.
The fastest version of this is automated. When a journal auto-syncs your trades and an AI coach grades them, you skip the manual spreadsheet and get straight to the one change that would have moved your results most.
