“Which BTC strikes have the most open interest within 7 days of expiry?”

◧

Fetches real data from the Cayo Largo API

What most people do

Manually check Deribit's OI column, one expiry at a time, with no way to rank or aggregate across strikes. Most traders never look at near-expiry OI concentration because the data is scattered across hundreds of rows.

What this gives you

A single ranked view of the heaviest strikes within 7 DTE, with USD notional, put/call breakdown, and GEX at each strike. When the top 3 strikes hold more than 40 pct of total OI, gamma pinning becomes the dominant short-term force.

Combine with the Gamma Pinning Map recipe to see which of these high-OI strikes are also magnetic. Link to the Cascade Events case study to see what happens when concentrated OI unwinds.
