Most trade journals fail for the same reason: they record the market instead of the trader. You do not need another note on why NVDA moved. You need a record of what you did and whether it matched your plan.
The plan field is the one almost everyone skips — and it is the only field that separates strategy problems from execution problems. Without it, a losing month tells you nothing.
If your off-plan trades lose more than your on-plan trades, your edge exists — you are just not taking it consistently. If they perform the same, the problem is the plan itself. Those are two completely different fixes, and only this field distinguishes them.
A journal you avoid is worse than none. Keep it to one row, log it right after the exit, and do not write essays. The trade journal keeps everything in your browser and exports to CSV, so you can also work in a spreadsheet.
