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.
Actions always reveal true beliefs regardless of stated intentions.
A disconnect between stated belief (having a stop) and action (exiting early) indicates the person doesn't truly accept the belief.
