What is a trading journal?
A trading journal is a structured record of every trade you take. It exists so you can see your real edge through win rate, average win, average loss, profit factor and expectancy, instead of guessing from memory.
What a trading journal actually is
A trading journal is a per-trade log that captures date, symbol, side, size, entry, exit, P&L and (optionally) notes and tags. It converts your trading history into numbers you can measure so you can separate skill from luck.
Why traders keep one
Without a journal, you remember your best and worst trades and forget the middle. A journal makes your true win rate, average win/loss and profit factor visible, which is the only honest way to know whether your strategy makes money.
What to log for every trade
At minimum: date, symbol, side (long/short), quantity, entry price, exit price, fees and realized P&L. Optional but powerful: setup/tag, screenshot, emotion and a one-line note on why you took the trade.
