Barchart lists contracts with high trading volume relative to open interest, alongside strike, expiration and volatility fields for further research.

About

The Unusual Stock Options Activity page selects contracts using volume, open interest and related criteria. Its table includes expiration, call or put type, strike, bid and ask, volume, open interest, Vol/OI, implied volatility and delta.

Date selection and filter entry points are available; full results and some advanced filters require Premier access. The help text states that options information is delayed approximately 25–30 minutes and updated about every five minutes during the session. Check the last-trade time before using a row.
