Cheap Volatility: A Lesson In Market Structure Mechanics

"The world breaks everyone, and afterward, some are strong at the broken places." - Ernest Hemingway   Alphacution has always been fascinated by the players. Unlike the world of sport, market players have unique potential to influence the field of play, and thus create a feedback loop that influences other players, and so on causing market ecosystem evolution.
