Research on sleep deprivation in decision-making roles, such as air traffic control and surgery, points the same way. Reaction times slow, error rates rise and risk perception shifts. After 17 to 19 hours awake, performance on some cognitive tasks resembles being mildly intoxicated.
Scalping asks for fast pattern recognition, steady discipline and quick execution. It is difficult to imagine a task more exposed to sleep loss.
The signs show up in the journal if looked for. Trades taken in the first session after a short night often show more rule breaks, more skipped stops and more revenge entries.
A simple experiment tracks hours slept next to daily results for 30 days. Even a rough correlation can be eye-opening.
Traders who work the Asian session from a European or American timezone face an added challenge, since the body clock resists. Compensating with caffeine rarely restores judgement.
Is sleep tracked here alongside results, and does the pattern show up?
