The HIRO Flow Alert flags large option flows in real time so users can be alerted to significant options activity in a given stock or ETF. Using a proprietary SpotGamma model, influenced by estimated hedging impact, the alert fires when flows may be driving price action in the underlying stock.
For all listed US options, SpotGamma calculates a specific “impact threshold” for the given security, and alerts the user when this threshold has been breached.
By default, HIRO Flow Alerts are automatically turned on for the most active stocks within the interface.
1. Alert Bell - When an alert fires, users will see the alert bell icon on the top right of the application turn red
2. Flow Alert - Additionally, “Flow” is displayed on the HIRO chart corresponding to the time the alert was triggered
