What you see
- Bars. Dealer gamma per BTC strike. IBIT strikes are mapped to BTC dollars by the price ratio between IBIT and BTC (shown as κ).
- Header. Net gamma for BTC, IBIT and combined (COMB), plus each book's share.
- IBIT closed. Shown outside US market hours, when IBIT may be its last print.
Controls on the DUALGEX panel
- TODAY / FRONT / WEEK / ALL
- Horizon. TODAY is the intraday pin (IBIT only when it expires today). FRONT (default) is the near-term stack with the next IBIT weekly. WEEK runs through Friday. ALL is every live expiry.
- net / split / signed
- Combined net, the two books side by side, or each side with its own sign.
- crypto / ibit
- Show one book only.
- abs / profile
- Magnitude only, or the cumulative profile across strikes.
Good to know
- Measured flow only (FLOW). There is no STD view, and a book with no tape yet contributes zero.
