The opening range breakout (ORB) strategy is a day trading strategy that consists of two key price levels, the opening range high (ORH) and the opening range low (ORL). Both, the ORH and the ORL breakout price levels are established for a given period after the market open. The opening range breakout occurs when the underlying trades above or below the ORH or the ORL price levels, respectively. The Ai.ORB bot sends an alert when either the ORH or the ORL breakout condition occurs for the first time in a given trading session for a given timeframe. The opening range breakout strategy works best with volatile stocks and high volume gappers.

The opening range high and the opening range low breakouts are shown above, where for the ORH breakout Target 3 was reached and for the ORL breakout Target 4 was reached. - - is an entry price zone and — are target price zones. Distance between an entry and target price zones is an expected bullish or bearish move. First target zone is provided by the Ai.ORB bot when an alert is sent.
