How to read this chain

Calls sit on the left, puts on the right, and every row is one strike. The highlighted row is the strike closest to spot. Open interest is the number of contracts still outstanding at that strike — positions that exist right now. Volume is how many traded on the session shown. Open interest builds slowly and marks where positioning has accumulated; volume spikes and marks where attention went today.

Strikes with no open interest and no trades on either side are omitted, and the ladder is trimmed to within 25% of spot — the far wings are almost entirely empty and say nothing about positioning.

Educational, not investment advice. Options involve risk. Open interest is reported with a one-session lag by OCC, so these levels describe positioning as of the last settled session, not live intraday flow.
