Stock options vs index options

Unlike index contracts, ONGC 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 — ONGC's ban status is shown above and on the F&O ban list.

Using the levels

Treat 225 and 250 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.
