Opening Range Breakout

The opening range breakout uses the high and low of the first few minutes of the session. Learn how it works, timeframes and entry rules.

Key takeaways

The opening range breakout (ORB) uses the high and low set in the first minutes of a trading session to determine breakout levels.
Traders typically use 5-minute, 15-minute or 30-minute opening ranges depending on their trading strategy and style.
A break above the high of the opening range can suggest bullish momentum, and a break below the low of the opening range can suggest bearish momentum.
Candle closing confirmation, volume and market conditions can help traders assess the strength of a possible breakout.
There can be false breakouts in ORB setups, so risk management is important. Traders need to plan their entry, stop loss, target and position size before taking a trade.

What is an Opening Range Breakout?

An opening range breakout is an intraday trading strategy based on the price range established in the first few minutes of a trading session.

The trader identifies two levels first:

The highest price reached in the selected opening period
The lowest price during the chosen opening period

This makes the opening range.

A price breakout above the high of the opening range can indicate a possible bullish breakout. If the price moves below the low of the opening range, it could signal a possible bearish breakout.

The important thing is that ORB does not attempt to anticipate the market direction before the range is formed. Instead, it waits for the price to move away from a defined level.

How does the Opening Range Breakout Strategy work?

The basic ORB strategy can be understood in four steps.

Step 1: Choose the opening period
Opening ranges are commonly used by traders at 5, 15 or 30 minutes. The 15-minute range approach (9:15 am to 9:30 am) is a commonly utilised approach for Indian markets.

Step 2: Mark the high and low
Once you have chosen your period, mark the high and low prices of the period on the chart. These will be the break levels.

Step 3: Wait for confirmation
The trader then waits for the price to decisively break above the range high or below the range low.

A breakout with increased volume can give additional confirmation, but the volume alone does not mean that the move will continue.

Step 4: Plan the trade
Before you enter, determine your entry price, stop loss level, target and position size. That is important as a breakout can fail and trade back inside the opening range.

What are the common ORB Timeframes?

There is no one time frame that all traders have to use. The decision will depend on the trader’s approach, risk appetite and the instrument being traded.

5-minute opening range
The 5-minute ORB takes the first 5 minutes of the regular trading session.

It can give earlier signals, but the smaller range can also mean more false breakouts, as the first price movement can be very volatile.

15-minute opening range
The 15-minute ORB uses the price range from 9:15 a.m. to 9:30 a.m.

This gives the market time to establish an initial range while allowing traders to get involved relatively early in the session.

30-minute opening range
A 30-minute ORB utilises the first 30 minutes of trading.

The range is generally wider, which can lower the number of signals. However, it can be preferred by traders who want to view more price information before entering a trade.

The best time frame should not be selected because it generates more trades. Whatever method you use, traders should backtest it on historical market conditions and understand the risk before trading with capital.

What are the entry rules for an ORB Strategy?

Entry rules should be established in advance of a trade rather than after the price action has begun.

For a bullish ORB setup, traders may look for:

A well-defined opening range.
Price moves above the opening range high.
Depending on the trader’s rule, a breakout candle closes above the level.
Supporting volume or other verification, as appropriate.
A pre-set stop loss and target.

For a bearish setup, the rules are reversed:

Find the range of openings.
Wait for the price to break below the low of the opening range.
Wait for confirmation of the breakdown.
Define stop loss and target.
Only enter if the trade fits the planned risk.

There is no setup that guarantees a profitable trade.

Stop-loss orders do not guarantee execution at the exact intended price, especially in situations where there are sharp price swings or shifts in liquidity.

What role does volume play in an ORB Strategy?

The break of a level by price is only one element of the setup.

Volume of trading can help a trader see if there is stronger participation behind the move.

For example, a breakout above the opening range high with increased volume may indicate greater participation than a breakout on extremely low volume.

But volume is not to be taken as a guarantee.

Even a high-volume breakout can fail, especially if the market is responding to news that is unexpected or reverses direction after the initial move.

So, volume is a better indicator when used as part of a larger trading plan than on its own as a signal.

What is a false breakout in ORB Trading?

A false breakout is when the price moves outside the opening range but fails to hold the move.

For example, a stock can move above ₹1,020 and attract buyers, and then quickly fall back below ₹1,020.

A trader who gets in straight away with no set exit plan can be in a loss position if the breakout turns around.

False breakouts can become more common when:

The market is going sideways.
The opening range is very restricted.
Volume is weak for trading
Surprise news is being priced into the stock.
The wider market is moving the other way.
The breakout has a long wick and little follow-through.

This is why traders should not think that every move outside of the opening range is a sure thing for a trade.
