Opening Range vs Opening Range Breakout (ORB)

The Opening Range is the high and low price boundary established during the first defined period of a trading session, typically the first 15 to 30 minutes, which sets the initial reference framework for intraday trading decisions.

The Opening Range Breakout (ORB) is a day trading strategy that enters a position when price breaks with volume confirmation above the Opening Range high or below the Opening Range low, anticipating directional continuation.
