Opening Range Breakout
The Opening Range Breakout (ORB) is a day-trading strategy based on the theory that the first few minutes of the trading day set the tone for the entire session.
How Opening Range Breakout Works
The strategy calculates the High and Low of the market during a specific time window at the start of the day.
- The Setup: It “locks in” the high and low of the first (for example) 30 minutes of trading.
- Long Entry: Triggered if the price breaks above that opening range’s High.
- Short Entry: Triggered if the price breaks below that opening range’s Low.
Strategic Considerations
- Morning Volatility: This captures the high-volume “price discovery” phase that happens when the market opens.
- Time Sensitivity: The choice of “Range Time” (5 min, 15 min, 30 min) is critical. A range that is too short causes whipsaws; a range that is too long might miss the bulk of the day’s move.
- Timeframes: Common ranges used are the first 5, 15, or 30 minutes of the trading day. The 15-minute timeframe is often considered the standard for balancing volatility with signal reliability.
