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.
Market patterns that appear identical on charts can produce different outcomes because the specific group of traders participating has changed, even if only by one participant.

They commit to taking every edge without picking and choosing based on confidence in outcome prediction.
