The HIRO Flow Alert flags large option flows in real time so you can be notified when significant options activity takes place for a name you follow. By default, Flow Alerts are automatically turned on for the most active US tickers within HIRO. To add Flow Alerts to the HIRO chart itself, click Indicators at the top of the chart and search for “SpotGamma Alerts” in the pop-up box.

Using a proprietary SpotGamma model based on the size of hedging impact, HIRO Flow Alerts fire when option flows are most likely to drive prices 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.

In addition to Flow Alerts, SpotGamma features notifications related to key levels that can be impactful when trading with HIRO: Put Wall Alerts, and Call Wall Alerts.

Put Wall Alerts: The Put Wall is considered SpotGamma’s major support level, based on current open interest. SpotGamma HIRO users can toggle specific alerts to be notified when the Put Wall is Breached, or when a name is Within 1% of its Put Wall.

Call Wall Alerts: The Call Wall is considered SpotGamma’s major resistance level, based on current open interest. SpotGamma HIRO users can toggle specific alerts to be notified when the Call Wall is Breached, or when a name is Within 1% of its Call Wall.

For HIRO Flow Alerts, Call Wall Alerts, and Put Wall Alerts, users will see the notification from the Alert Bell in the top right of the dashboard, and in the HIRO  Alerts section (bottom right corner of the page) if desired.
