Why Trading Strategies Stop Working
Summary
Host Mark explores why trading strategies lose effectiveness, arguing that edge erodes as participants adapt and front-run known patterns, illustrated by the decline of the Turtle Trading system. He explains that edge is not a permanent chart property but a consequence of shifting participant behavior and incentives.
