Frequently asked

Is SPX open interest the same as volume?

No. Volume counts contracts traded in a session; open interest counts contracts still outstanding, so it shows durable positioning rather than intraday churn.

Why is SPX open interest clustered at round strikes?

Institutional hedges and structured products concentrate at round levels, which is why those strikes carry the heaviest gamma and act as expiry reference points.

Does this chain include 0DTE contracts?

It aggregates listed SPX strikes across expiries, so same-day contracts are reflected in the totals shown.
