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.
Successful traders think probabilistically about their edge, understanding that individual trade outcomes are random within a distribution.
They commit to taking every edge without picking and choosing based on confidence in outcome prediction.

The typical trader won't predefine the risk of getting into a trade because he doesn't believe it's necessary. The only way he could believe 'it isn't necessary' is if he believes he knows what's going to happen next
