What does the "Next Expiry" filter indicate? When viewing the chart for a single stock, you can toggle on and off the "Next Expiry" filter on both the Total and Put/Call chart. The Next Expiry filter highlights the activity across stocks relative to only the next available expiration. This means that we are showing you the options flow that is tied to the next available exploration for that instrument. For SPX, SPY, and QQQ, this is typically done in the same trading day. For large stocks like Apple and Tesla, the next expiry filter will generally highlight the flow that is tied to the next Friday expiration.
