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.
True trading consistency emerges naturally from aligned beliefs and attitudes, not from external market conditions or forced effort.
It is a state of being rather than a state of doing.
