Condition: When a HIRO Flow Alert fires for a name, watch the live options Flow Data beneath the HIRO chart to isolate the largest trade(s) taking place at the same time; if HIRO is moving in the same direction as that trade, this gives confidence that the move may be driving meaningful price action.

In this scenario, one feasible strategy is buying deep in-the-money 0DTE spreads:

• If the price has risen sharply: Buy an in-the-money put spread
• If the price has dropped sharply: Buy an in-the-money call spread

Pro Tip: Configure your alerts to show the stocks, ETFs, or indices you are most interested in to make sure you get notified when major order flow activity occurs in these tickers.
