Key Strike Levels
The open‑interest (OI) clusters around the ₹170‑₹177.5 band suggest a tight market‑view range. The highest call OI sits at the ₹100 strike, acting as a resistance ceiling, while the largest put OI is anchored at the ₹100 strike, forming a support floor. Together they bracket the underlying spot of ₹173.4, indicating limited directional bias ahead of the 29‑Sep‑2026 expiry.

Fresh OI additions are evident at the ₹177.5 call (↑ +1, 49,100) and the ₹170 call (↑ +1, 45,550), pointing to new long‑call positioning near the upper band. On the put side, incremental OI appears at the ₹172.5 put (↑ +1, 52,650) and the ₹177.5 put (↑ +1, 02,950), reflecting additional short‑call hedge or speculative put interest. The ₹175 put also sees a rise (+95,850), reinforcing downside protection around the spot level.
