Market Structure & Dealer Flow - How SPY Really Moves

Price does not move at random - it is pushed by structure and by the forced hedging of options dealers. This guide maps the forces under the tape: VWAP and the session, dealer gamma and the flip, the order book and its illusions, volume, the scheduled catalysts, and the chart patterns worth (and not worth) watching.

This is the layer NoVo reads all session - where the flows are, not where the crowd is guessing.
