OI Buildup Read

Neutral buildup prevails with price unchanged and total OI static, indicating balanced long and short additions. No fresh directional commitment is observed in options, reflecting market indecision ahead of key data. Signal strength is weak, constrained by zero net OI expansion.

Put-Call Ratio Signal

PCR holds flat at 0.868, within neutral range—below 1 and above 0.7—suggesting neither excessive fear nor greed. The unchanged ratio from the prior day confirms sustained balance in put and call positioning.

Futures Confirmation

Futures OI remains at zero with no open positions, eliminating futures-driven confirmation of options sentiment. The absence of futures activity decouples spot-directional leverage from options dynamics.

Bias for Tomorrow

Bias is neutral; breakout above ₹435 or breakdown below ₹415 invalidates range-bound stance.
