Open Interest (OI) data tells you how many contracts are outstanding in the market — it does not tell you direction on its own, but combined with price, it reveals whether moves are being driven by new money entering or existing positions being covered.
For Nasdaq Futures traders, the most practical application of OI analysis comes from the options market. The Nasdaq is heavily influenced by the options gamma exposure of dealers who hedge large positions. When price approaches a major call wall or put wall, you will often see strong reactions because dealers are forced to hedge their books — which creates directional flows in the futures market.
This section covers: Open Interest mechanics, how to read OI changes, gamma exposure basics, call/put wall identification, and how to incorporate this data into your daily preparation process for NQ/MNQ futures.
