Introducing: Taker-Flow-Based Gamma Exposure
Introducing a flow-based approach to Gamma Exposure (GEX) tailored for crypto options markets. Unlike traditional equity markets, crypto options exhibit distinct participant behavior and trade motivations, making conventional GEX heuristics unreliable. By leveraging taker-level trade data from venues like Deribit, this methodology reconstructs dealer positioning by mirroring cumulative taker flows—strike by strike and maturity by maturity—rather than relying on static assumptions. The resulting GEX metric identifies zones where dealer hedging flows may either stabilize prices (positive gamma, causing "pinning") or amplify volatility (negative gamma, creating "slippery" zones). This framework provides a dynamic, realistic view of market structure, helping traders anticipate volatility regimes and key price levels in assets like BTC, ETH, and SOL.
