Reading Timeseries Option Chain
Compare strike-level option observations across timestamps, with measure, transpose, cumulative and Greeks controls.
Check quote freshness, source time, contract coverage and displayed units; OI does not identify the initiating buyer or seller.
- Read the selected measurement by strike and timestamp, checking CE and PE column order.
- Distinguish interval changes from cumulative aggregation and absolute position levels.
- Use transpose and Greeks controls with a consistent expiry and observation window.
