BLUE STAR Option Chain (NSE) — Live OI, PCR & Greeks

Reading BLUESTARCO's chain today

The table above shows all active BLUESTARCO strikes for the 28 Jul 2026 monthly expiry. Right now the heaviest Call OI sits at 1,700 (1,95,975 OI) and the heaviest Put OI at 1,600 (1,70,300), placing the option writers' range at 1,600–1,700 against a spot of 1,636.4. BLUESTARCO's PCR of 0.67 reads bearish (call-heavy), and max pain for the series is 1,600.

Stock options vs index options

Unlike index contracts, BLUESTARCO options are deliverable — positions held into expiry can result in physical settlement, so most traders square off before the final sessions. Liquidity concentrates in the near-month at-the-money strikes; quotes far out-of-the-money can carry wide spreads, so check LTP against the bid-ask before sizing. Results announcements, sector news and F&O ban-list entry are the three events that reshape this chain fastest — BLUESTARCO's ban status is shown above and on the F&O ban list.

Using the levels

Treat 1,600 and 1,700 as the defended zone for this series, and confirm any breakout against fresh buildup rather than standing OI. For multi-leg positions on these strikes, the strategy builder imports this chain's live prices.
