In trading it tends to arrive gradually. Sessions feel heavier, the plan is followed less, small mistakes multiply, and interest in the work fades. Because trading offers constant feedback and money at stake, the stress is easy to mistake for ordinary determination.
Poor sleep, long hours at the screen, no days off and a strong attachment to each result all feed it. A bad record can follow burnout as much as cause it, which makes the cycle hard to see from inside.
Early signs are behavioural and can be written down: skipped reviews, later starts to preparation, more trades without a clear setup, shorter patience after losses. A journal shows these changes before you feel them.
Prevention is mostly about structure. Fixed trading hours, a daily loss limit, regular days away from the screen, enough sleep and activity outside trading. None of it is glamorous and all of it protects your decision quality.
If exhaustion, low mood or loss of interest persist, talk to a doctor or a qualified professional. A trading journal can notice patterns but cannot diagnose or treat anything.
