OI Buildup Pattern

The current expiry shows a neutral buildup, meaning that both the spot price and the total open‑interest (OI) have remained essentially flat from the previous session. With the index price unchanged at ₹24,078.3 and total OI unchanged, there is no clear dominance of either long‑building (price ↑ + OI ↑) or short‑building (price ↓ + OI ↑) dynamics. This equilibrium suggests that market participants are holding existing positions rather than adding new directional bets, leading to a balanced outlook on the underlying.

Put‑Call Ratio

The put‑call ratio (PCR) stands at 0.701, a modest rise from yesterday’s 0.635. The higher PCR indicates a relative increase in put open‑interest compared with call open‑interest, though the level remains below 1.0, reflecting still‑predominant call activity.

Futures OI

Futures open‑interest registers a net change of zero, indicating that the number of long and short contracts opened during the session exactly offset the contracts that were closed. This flat futures OI underscores a lack of net positioning pressure from the futures segment for this expiry.

Data Summary

Total call OI is 1,994,57,700 versus put OI of 1,398,81,950, with a neutral buildup and unchanged overall OI.
