Mental Capital
The finite reservoir of cognitive energy, emotional resilience, and focus available for trading — when it runs out, decision quality collapses.
Mental capital is the psychological resource you bring to the screen. It depletes under stress, decision fatigue, poor sleep, personal stress, and after a string of losses. When it is low, your ability to follow rules, manage emotions, and read the market correctly degrades — often before you notice it has.
Many traders focus obsessively on financial capital while treating mental capital as inexhaustible. It is not. A trader operating on four hours of sleep and three straight days of losses is not the same trader as the one who is rested, recovered, and clear-headed. The seat is the same; the instrument is different.
Protect mental capital actively: strict session length limits, rest days after drawdowns, physical exercise, and a hard rule against trading when emotionally compromised. Capital preservation starts with the person behind the keyboard.
