Screen fatigue and the cost of staring
Posted: Sat Oct 31, 2026 9:01 pm
Hours of watching a one-minute chart tires the eyes and dulls attention. Blink rate drops, focus narrows, and details slip by.
The effects show up in trading: a missed signal, a misread level, a wrong size in the order window. They also show up physically, with headaches and tension in the neck and shoulders.
Some basics help. The 20-20-20 habit, looking at something twenty feet away for twenty seconds every twenty minutes, takes almost no time. Adequate lighting and a monitor at the right distance reduce strain. Dark mode can help in the evening, though it is a matter of taste.
Scheduled sessions, with fixed start and end times, prevent the open-ended watching that wears people down. A scalper who trades two focused hours often does better than one who sits for six.
Nobody gets extra credit for staring. If the setup list is empty, closing the platform is a legitimate trade decision.
How long is a typical focused session before quality drops, and what is done about eye strain?
