Reading these numbers
- PCR 1.289 — A PCR above 1 means more put OI than call OI exists across the chain. Historically, elevated PCR correlates with market support (put writers are short puts and want the market to stay up).
- Max Pain at 24,200 — 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 24,189.9 – 24,343.5 — The max-pain strike (24,200) 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.
