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.
From any individual trader's perspective, anything can happen in the market because a single large trader can move prices in ways technical analysis cannot predict.
This reality must be accepted without internal conflict.
