What is a trading journal?

A trading journal is a record of every trade you take — what you traded, why you took it, how it was sized and risked, and what actually happened. It looks like a logbook, but it works like a mirror: the point isn't to track P&L (your broker already does that), it's to see your own decisions clearly enough to fix them.

What a trading journal actually looks like

Every journal starts with the same raw data your broker statement has: symbol, direction, size, entry and exit price and time, fees, and P&L. That part is bookkeeping. What separates a journal that improves your trading from one that just accumulates rows is three additions a statement can never give you: a snapshot of the chart you actually traded, the plan you had going in, and an honest review after the fact. See the full breakdown in what to put in a trading journal.

Why traders keep one

Your memory of a trade isn't reliable — a week later you remember the plan you meant to follow, not the one you actually followed. A journal is the only unbiased record of what you really did. Reviewing it on a regular cadence is how you catch the mistakes that repeat (oversizing after a loss, cutting winners early, skipping the stop) before they cost you another month. It's also how you find out what's actually working, instead of guessing from a gut feel about “how the week went.”

Paper, spreadsheet, or app?

All three can work — the habit matters more than the tool. A notebook is zero-friction but hard to search or chart. A spreadsheet adds structure and basic stats but can't hold a chart screenshot or auto-import fills. A dedicated journal app adds broker sync, chart capture, and (in ChartRecap's case) AI-graded reviews on top of the spreadsheet layer. See trading journal vs spreadsheet for where each one breaks down.

Does the market you trade change anything?

Not the core idea — a journal is the same for stocks, forex, futures, options, or crypto: log the setup, size the risk, review the outcome. What changes is the instrument-specific detail (lot size in forex, strike and expiry in options, contract specs in futures). See the forex, futures, and options journal pages for the details specific to each.
