Opening Range Breakout Strategy
The opening range breakout (ORB) is a classic day trading strategy that defines a price range during the first 15-30 minutes of a trading session and then trades the breakout from that range. The logic is that the opening range captures the initial battle between buyers and sellers, and the breakout direction often defines the trend for the rest of the session.
How the Opening Range Breakout Works
The opening minutes of a trading session are among the most volatile and informative. Institutional traders place orders based on overnight developments, economic data, and pre-market analysis. This concentrated activity creates a well-defined high and low within the first 15, 30, or 60 minutes — this is the opening range.
Once the range is established, you watch for price to break above the high (bullish signal) or below the low (bearish signal). The breakout is your entry trigger. The opening range acts as a natural support and resistance zone, and the breakout suggests one side has won the opening battle.
The strategy is mechanical and rules-based, making it suitable for traders who prefer structured approaches. Mark Minervini, Toby Crabel, and other well-known traders have popularised variations of the ORB. It works across forex, indices, and individual stocks.
How to Enter the Trade
1. Define the Opening Range
Mark the high and low of the first 30 minutes of the relevant session (London open for forex, 9:30 AM for US equities). Use the 5-minute chart. The range should be clear and well-defined — avoid setups where the range is unusually wide (more than 1.5x the average daily range).
2. Place Breakout Orders
Set a buy stop 1-2 pips above the opening range high and a sell stop 1-2 pips below the opening range low. This way, whichever direction breaks first automatically triggers your entry. Once one order fills, cancel the other.
3. Confirm With Volume
The breakout candle should show increased volume compared to the candles within the opening range. A breakout on declining volume is more likely to fail. Volume confirmation is particularly important for stock and index ORB setups.
4. Filter With Trend
For higher probability, only take ORB trades in the direction of the higher-timeframe trend. If the daily chart is bullish, only take the long breakout. This filters out counter-trend breakouts that are more likely to fail.
How to Manage and Exit
Stop-Loss
Place the stop on the opposite side of the opening range. For a long breakout, the stop goes below the opening range low. For a short breakout, above the opening range high. This represents the maximum risk and defines your position size.
Take-Profit
Use a multiple of the opening range width as your target. A target of 1.5x to 2x the range width works well. For example, if the opening range is 20 pips, target 30-40 pips from the breakout point. Alternatively, use the next significant support/resistance level.
Session End Exit
Close all ORB positions before the session ends. The opening range thesis is specific to that session — carrying it overnight introduces new risks that the setup does not account for.
Example: S&P 500 Opening Range Breakout
Opening Range: The S&P 500 opens at 9:30 AM ET. By 10:00 AM, the 30-minute high is 5,280 and the low is 5,260 — a 20-point opening range.
Orders: Buy stop at 5,281. Sell stop at 5,259.
Breakout: At 10:15 AM, price breaks above 5,281 with strong volume. The buy stop triggers. Cancel the sell stop.
Stop-loss: 5,259 (below the opening range low, 22-point risk).
Target: 5,281 + (20 x 1.5) = 5,311 (30-point target, 1.4:1 risk-reward).
Outcome: Price reaches 5,311 by 1:00 PM. Close for 30 points profit.
