Reading Options Data
Compare strike-level OI, OI change, volume and PCR in a selected session and replay window.
Check quote freshness, source time, contract coverage and displayed units; OI does not identify the initiating buyer or seller.
- Keep symbol, expiry, strike range and replay start/end observations fixed when comparing charts.
- Read total OI, OI change, traded volume and strike PCR as separate measurements.
- Compare CE and PE distributions around ATM, then inspect the individual contracts.
