What is Opening Range Breakout?

Opening Range Breakout (ORB) is a popular intraday trading strategy that focuses on the price action during the first few minutes of the trading session. Traders identify the highest and lowest prices within this initial period, then look for breakouts above or below these levels.

The strategy capitalizes on the momentum and volatility that often occurs when the market digests overnight news and establishes the day's trading direction. ORB traders believe that significant moves often begin with a break of the opening range.

How Opening Range Breakout Works

The ORB Process

Step 1: Define the Opening Range

  • • Common timeframes: 5, 15, or 30 minutes after market open
  • • Record the highest high and lowest low during this period
  • • Mark these levels as resistance (high) and support (low)
  • • The range becomes your trading boundaries

Step 2: Wait for the Breakout

  • • Monitor price action after the opening range period ends
  • • Look for decisive breaks above the high or below the low
  • • Confirm breakout with increased volume
  • • Enter trade in the direction of the breakout

Step 3: Manage the Trade

  • • Set stop loss just inside the opening range
  • • Target 1:2 or 1:3 risk-reward ratio minimum
  • • Consider trailing stops as trade moves favorably
  • • Exit before major support/resistance levels

Common ORB Variations

5-Minute ORB

  • • Most aggressive approach
  • • Quick entry and exit
  • • Higher frequency trading
  • • Requires constant monitoring

15-30 Minute ORB

  • • More conservative approach
  • • Better signal quality
  • • Reduced false breakouts
  • • Suitable for part-time traders
