Opening Range Breakout Trading Strategy

2023-04-03 • Updated

Hello traders! Trading strategies are essential for any profitable trader as they give the needed consistency in making decisions. Today we tell you about one of the most important reversal and continuation chart patterns for the stock market – opening range breakouts. We will give you a history of trading strategy based on this pattern, a number of examples and several useful hints. Let’s go!

What is Opening Range breakouts?

The opening range is the space between the high and the low of the price for a given period after the market opens. Usually, this period is less than an hour long, and the opening range breakout (ORB) strategy uses these levels as entry points. Generally, traders use 5-, 15-, and 30-minute timeframes to trade ORB.

For example, if you are defining and trading the 15-minute opening range of Apple stock, then you are evaluating the high-low range of APPLE from the opening bell to 15 minutes following the opening bell. Within this opening range, the two most important levels that you would be watching would be the high and the low price within the first 15 minutes. Look at the figure to get the idea more clearly.


Here you can see that the trading session started with a gap in price. We are using a 15-minute opening range for SPCE stock, so we need to look at the M5 chart. After the price has created an opening range, we can look for entries on the breakout.

The ORB analysis tends to work the best on the markets that have a clearly defined opening and closing time, like stocks. The US stock market opens at 16:30 GMT+3, five days a week, so you can prepare for trading and have no worries of missing the trade.

History of ORB

The strategy was invented back in 1960-s by famous American trader and investor Arthur Merrill, who used it for almost 20 years in trading Dow Jones Industrial Average index. Although the strategy has some variations in it, the basis remains the same. To find an opening range some traders use a short-term moving average, most commonly a three-day average.

Another well-known trader, Sheldon Knight, used the percentage of the difference between an N-day high and N-day low to find a range. We assume that it’s better to keep things as simple as we can. Thus, using a short-term averages or highs and lows of a certain day is less effective than using price action at the start of the trading session.

Size of the Opening Range Breakouts

There are two ways of measuring the size of the ORB. Here is the first one: the first candle is the last one from the trading session of the previous day. The second candle is the first one created when the market opens. To get the range size you need to take the high/low of the previous closing and the high/low of the today’s opening candle. The distance between these two prices is the size of the opening range. Now see how we measure the size of a range:


The other way of measuring the ORB is simply the high and low of a given period after the market opens. This period is generally the first 30 minutes or the first hour of trading.

During this period, you want to identify the high and low of the day. In addition, you will also want to account for the pre-market highs and lows, as these levels will often act like a magnet for price action after the bell rings. Let’s look at the same figure with a different measuring.


Opening Range Breakout Calculator

The most important part of the opening range trading is the breakout. You already know that. What you probably don’t know is that you can use an ORB calculator to help you find trading opportunities and use them in your favor. You can Google “Opening Range Breakout Calculator” to find an example of such site.

These sites calculate the high and the low of the opening range for you, so it should be easier to start trading. However, we strongly recommend you watch our Gap and Go video because in it you will find several tools to look for gaps in price. Thus, it will be much easier for you to set ORB levels.

ORB Trading Strategy

The strategy consists of several steps:

  1. Look for gaps in stock’s prices. Gap scanners are available online for free, so this part shouldn’t be hard. In addition, you can watch our Gap and Go video. It will provide more information about gap searching.


  2. After you found a suitable gap, open the chart of a stock, and wait for the start of the trading session. For the US stocks, the action begins at 16:30 GMT+2 from September to March, and at 16:30 GMT+3 from March to September.


  3. Depending on the timeframe you have chosen, wait for first 4-6 candles to close. Usually, traders choose five-minute candles. Then, you should define the high and the low of the range, as we did earlier in this tutorial.


  4. On the breakout of the range, you enter the trade in the direction of the movement. Your stop loss should be in the range (below the range high for long trades and above the range low for short trades). To maintain the risk-management, take profit is usually placed twice as far as stop loss.


Tips for better trading:

  • Close part of your trade on the halfway to the Take Profit. This way, your trade will become a risk-free one. It will help you to withstand the periods when the trade goes wrong.
  • Don’t enter the trade you are not sure about, otherwise you will become nervous and less focused.
  • Wait for the candle to close above the opening range to avoid fake breakouts.
