Trading psychology, belief systems, and probability-based execution.
Mark Douglas explains why consistency in trading comes from mindset, risk acceptance, and learning to think in probabilities instead of trying to predict every outcome.
Every thought, statement, and action as a trader reinforces some belief in the mental system.
Consistency comes from repeatedly reinforcing aligned beliefs.
