Live Open Interest Analysis for Indian Options
OI, OI change and buildup across every strike — read positioning as it forms.
Open interest tells you where positions are being built and unwound — but only if you can see it change live. Quintal Mind streams OI and OI change across the full Nifty, BankNifty and Sensex chain so you spot buildup the moment it happens.
Each strike is classified by buildup type — long buildup, short buildup, long unwinding or short covering — using the relationship between price and OI change, so the positioning story reads at a glance.
