How to keep a trading journal that actually makes you better

Almost every profitable trader keeps a journal. Not because writing makes money, but because without data there's no way to know what works. Memory lies: we remember the spectacular trades and forget the twenty small losses that eat the account.

A good journal isn't a spreadsheet with each day's result. It's a record that answers concrete questions: which session do I lose most in? Which setup actually pays? Which mistake costs me the most?

What to log on every trade

• The facts: symbol, direction, entry, stop loss, take profit, exit, size and result (in money and in R).
• The context: strategy or setup, timeframe, session (London, New York…) and why you entered.
• Your state: how you felt (calm, anxious, FOMO…). Emotions explain many losses.
• The rules: which rules of your plan you followed and which you didn't.
• The mistakes: moving the stop, late entry, overtrading… Always tag them, even if the trade won.
• Screenshots: one at entry, one at exit. In the review, seeing the chart beats any note.

Measure in R, not just money

R is the result divided by what you risked. Risk 100 and make 250 and you made 2.5R. Measuring in R makes trades of different sizes comparable and shows your system's real quality regardless of account size.

The weekly review: where improvement happens

Logging without reviewing is of little use. Block 30 minutes every weekend and answer:

• What were my best and worst trades, and why?
• What percentage of my rules did I follow?
• Which mistake repeated and how much did it cost?
• What will I do differently next week? (one concrete thing)

The metrics that matter

• Expectancy: how much you make per trade on average, in R. If it's negative, no risk manager will save you.
• Profit factor: gross wins divided by gross losses. Above 1.5 is solid.
• Win rate and average R:R: they go together. 35% wins is excellent with 3R winners and ruinous with 1R.
• Max drawdown: the worst drop from a peak. It tells you how much risk per trade you can handle.

Common journaling mistakes

• Logging only the good trades (or only the bad ones).
• Leaving it for the end of the day and filling it in from memory.
• Not tagging mistakes when the trade won: the mistake is still there, you just got lucky.
• Having so many fields you give up. A few data points always beat many sometimes.
