BANKEX options data download

BANKEX options data is sold on Options Data (optionsdata.shop) in the BSE Complete packs, together with SENSEX, at 1-minute with futures and the index. The files use the same layout as SENSEX (SENSEX options cover NOV 2023 → NOV 2026), so one loader handles both. Each pack page lists its exact dates.

What is in the BSE packs

BANKEX and SENSEX options, every strike that traded, calls and puts, one file per day per listed expiry, named the same way as the SENSEX files, plus futures and the index for both.

BANKEX is a banking-sector index on BSE, useful as a second banking series next to your NSE work, or to compare sector and benchmark option pricing on the same days.

One loader for both BSE indices

Check strike spacing per index rather than assuming it; round at-the-money strikes to the spacing you find.
