A trading journal is a structured record of every trade a trader takes — instrument, direction, entry, exit, size, the reason for the trade, how it was managed, and the emotional state behind it. Reviewed regularly, it turns trading history into a feedback loop instead of a blur.
Its value comes from separating decision quality from outcome. Markets pay bad decisions and punish good ones in the short run, so profit-and-loss alone is a misleading teacher; a journal lets you sort trades by setup, time of day, and emotion to find which patterns actually make money and which habits — revenge trades, moved stops, oversized low-conviction entries — quietly drain the account.
The metrics worth tracking over time are win rate, average win against average loss, profit factor, and expectancy, judged on samples rather than single trades. Secuora includes a free journal — 20 trades, no card required — with emotion, rule, and confluence tracking, screenshots, and a P&L calendar.
