More Decisions, Worse Outcomes
Summary
Bill Johnson argues that frequent trading and timing entries or exits often worsen outcomes by multiplying decision errors and costs. Using coin-flip analogies, he shows that active intervention usually just shifts you within the same unfavorable probability distribution. Instead of chasing control, traders should focus on price as the true edge, ensuring each decision mathematically improves their position rather than adding noise.
