How to keep a trading journal you will actually use
What to record for each trade, when to record it, and how to review it, without spending your evening on a spreadsheet.
Why most trading journals get abandoned
A journal only helps if it is complete. Most traders start with a spreadsheet, fill it in for a week, then skip the losing days, which are exactly the days that matter. The problem is not discipline. It is that writing up trades after the session is slow, and memory rewrites the story.
So the rule for a journal that lasts is simple: capture the reason while it is true, and let software do the bookkeeping.
What to record for every trade
Numbers are the easy part; your platform already has them. What it does not have is context.
- Setup: what you saw, in one phrase ("failed breakdown of the overnight low").
- Trigger: the exact thing that made you click.
- Plan: where you are wrong (stop) and where you take profit.
- State: calm, rushed, bored, revenge.
- Exit: why you got out, and whether it was the plan.
- Rules: did you follow them? If not, which one did you break?
Record at entry and exit, not at night
Your reasons at 9:41 are different from the reasons you remember at 18:00. Recording a few seconds at entry and exit keeps the real story. Voice is the fastest way: saying "short, failed breakdown, stop above the high" takes five seconds; typing it mid-trade does not happen.
Review weekly with three questions
Once a week, look at the trades together, not one by one.
- Which setups made money, and which only felt good?
- What did the trades where you broke a rule cost in total?
- When (time of day, after which kind of trade) do your worst decisions happen?
Keep it honest
A journal is not a highlight reel. Log every trade, including the ones you are not proud of. If a tool imports every fill from your platform, nothing can be skipped, and the review is based on all of your trades rather than the ones you remembered to write down.
How Afterfill does this
Afterfill imports every fill from NinjaTrader, MetaTrader 5, TopstepX, Bybit, Binance or Hyperliquid, records a short voice note when a position opens and closes, and uses AI to turn the note into setup, plan and rule tags. The weekly questions above are answered from your own trades. It never gives trade advice.
