What it shows
Open interest is the number of option contracts outstanding at each strike. Where it is heavily concentrated, option writers have a large stake in price staying on one side of that level — which is why the highest-OI strikes are often read as resistance on the call side and support on the put side.
The module shows call and put OI side by side across strikes, how OI has changed through the session, the put-call ratio trend, and where the largest OI "walls" sit, so shifts in positioning are visible as they happen.
