Understand Options Flow, GEX and Dealer Positioning
Options flow and gamma exposure can help frame market structure. They are context tools—not predictions—and should be considered alongside price, liquidity, volatility and risk.
Options flow in context
Volume, open interest, blocks and sweeps may reveal activity worth investigating. They do not show a complete thesis, timing, or whether an option was bought to open, sold, or used as a hedge.
Gamma and dealer positioning
Gamma exposure and dealer hedging can influence how market participants discuss potential volatility, call walls, put walls and gamma flips. These concepts are probabilistic and can change as price and positioning change.
Use structure, not certainty
The goal is to improve situational awareness and trade planning. Members should avoid treating any flow or positioning measure as a standalone entry signal.

Questions traders ask
What is GEX?
Gamma exposure is a way of describing how options positioning may affect hedging dynamics as market prices move.
Can options flow predict a market move?
No. It may add context, but it cannot reliably predict a future price move or remove trading risk.
