Reading these numbers
- PCR 0.217 — 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 78,900 — 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 77,797.9 – 78,197.6 — The index closed below max pain (78,900) — below-pain positioning may have supported downward drift into expiry.
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.
