Trading psychology covers everything between the setup on the chart and the click: fear of missing out, the urge to win back a loss, hesitation after a losing streak, overconfidence after a winning one, and plain fatigue. Most traders know their plan; trading psychology is about why they do not follow it on some days.
The patterns that cost the most
- Tilt: decisions degrade after a loss or a run of losses.
- FOMO: chasing a move that already happened.
- Revenge trading: an unplanned trade to recover a loss quickly.
- Overtrading: taking trades out of boredom or the need to be in the market.
- Hesitation: skipping valid setups after losses, so the winners that should repair the drawdown are missed.
From naming emotions to measuring them
Writing "felt anxious" in a note is a start, but it cannot be counted. A measurable approach rates a few states on a fixed scale at fixed moments:
Single-item ratings like these come from mood research (the MDBF questionnaire measures the same three dimensions). They take seconds, and after a few weeks they can be set against results: do days that start with poor sleep produce more mistakes? Do trades entered at 1 or 2 on calm carry most of the losses?
What a journal can and cannot do
A journal will not make you calm. It shows, with your own numbers, which states cost you money, so that "do not trade when tired" becomes a rule with a price on it instead of advice.
In SetupBook
The dashboard's Today card has a three-tap morning check-in (sleep, energy, mood); the trade form asks for calm at entry in step 1 and an emotion label; the day note holds an end-of-day mood. Analytics turns them into four cards: results by emotion, your state over time next to daily P&L, days grouped by morning state, and the mistake share by state at entry. Everything is optional and there are no reminders.
