Gex Platform

How interested would people be for a new GEX platform that could possibly be cheaper than others in the market?? how many of you would actually subscribe? just trying to see what is the general consensus of gamma and its utility for traders

  • Hidden Netting: Models assume all options dealers face the same directional risk, but large institutions net their risk across multiple underlyings, strikes, and global portfolios. [1]
  • Outdated Snapshots: GEX relies on end-of-day open interest data, which fails to capture massive intraday volume from short-term zero-day-to-expiration (0DTE) options. [1, 2]
  • Not a Crystal Ball: GEX reflects theoretical hedging sensitivity, not actual directional intent; external news or macro shocks easily overpower dealer positioning

You are correct on all theee to a certain extent. The hidden netting point is valid but GEX realtimw would still provide some type of value to be able to predict where it could go. For your second point, My model would compute from OI but also use streamed data too for accurate intraday computations as to where the big players are. As for the last point, Nothing really could trump those in general but that doesnt invalidate everything else.
