Index futures don't trade in a vacuum. When SPX moves, options market makers must execute massive offsetting trades to stay hedged — which flows directly into ES futures.
This dealer hedging is mechanical and non-discretionary. It follows mathematical rules that don't care about chart patterns, news, or market sentiment. The result: specific price levels where large amounts of automated buying or selling will occur.
Futures traders who ignore this data are competing without knowing where hundreds of billions in dealer hedging flows are going to step next.
