Reading these numbers
- PCR 0.764 — A PCR below 1 means more call OI than put OI. Call writers dominate, which can act as a resistance cap on rallies near heavily-written call strikes.
- Max Pain at 75,600 — The theoretical price at which the index would cause the most option contracts to expire worthless, minimising the total payout from option writers. Often acts as an intraday or expiry-week magnet, especially in low-volatility sessions.
- Spot ranged 75,006.9 – 75,737.2 — The max-pain strike (75,600) fell within the session's range — the index traded around the pain point during this session.
These are aggregate summaries of market positioning data, not trading signals. PCR and
max pain are widely-watched indicators but are not predictive on their own.
