What does the "Total" HIRO Stock Chart indicate? When viewing the chart for a single stock, "Total" is the default view. This total view shows the delta hedging pressure in one line and can be filtered by All Trades, Next Expiry or Retail. All Trades Filter Shows the delta hedging pressure across HIRO with the embedded SpotGamma proprietary logic. 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. Retail Filter Allows you to see the retail-only Delta hedging pressure based on non-institutional trades. SpotGamma uses some proprietary logic to identify and reveal which trades are likely retail-driven. SpotGamma Alpha subscribers can access the SpotGamma HIRO Indicator here.
