Executive Definition & Core Answer

The Opening Range Breakout (ORB) is a premier intraday momentum strategy that capitalizes on institutional order flow by trading breaks outside the high or low established during the first 15 minutes of the market session (9:30–9:45 AM EST). In paper trading, mastering ORB requires confirming relative volume (RVOL > 1.8x), entering on pullback retests, and targeting 2:1 payoffs.
