The Opening Range Breakout (ORB) is one of the best-known intraday strategies. It defines the price range of the first minutes after the market open and trades when price breaks that range, assuming the breakout marks the day's direction.
Why the open
In the first minutes after the open, the bulk of the session's volume and volatility comes in. The highs and lows formed in that window tend to act as references that the rest of the day respects or breaks. Hence the idea: if price breaks that range with force, it can drag the move along.
The false-breakout problem
Most breakouts fail. The edge of the range is exactly where stops pile up and where price fakes moves to hunt them. A naive ORB —entering on any breakout— tends to bleed on sideways days, and there are many of those.
What separates an ORB that works from one that doesn't
Filter the context: don't trade days with no trend or volatility, where the breakout has no support.
Confirm the breakout instead of entering on the first touch of the level.
Manage risk with a stop and targets defined in advance.
Without those filters, ORB is a pretty idea that loses money. With them, and on directional days, it is a reasonable strategy. It is not magic.
Is it for you?
It is intraday, so it requires you to be there or to automate it, and it depends on the market regime: it shines on directional days and steps aside (or should) on sideways ones.
This is exactly how we approach ORB automatically: regime filter, breakout confirmation and management with a stop and targets.
Frequently asked questions
It depends on the filtering and the market. Without context filters, badly. With them and on directional days, it is a reasonable strategy. It is not magic and it does not work all the time.

Risk Disclosure: Futures and forex trading involves substantial risk and is not appropriate for all investors. An investor could potentially lose all or more than the initial investment. Risk capital is money that can be lost without jeopardizing one's financial security or lifestyle. Only risk capital should be used for trading and only those with sufficient risk capital should consider trading. Past results are not necessarily indicative of future results.
Hypothetical Performance Disclosure: Hypothetical performance results have many inherent limitations, some of which are described below. No representation is being made that any account will or is likely to achieve profits or losses similar to those shown. In fact, there are frequently sharp differences between hypothetical performance results and the actual results subsequently achieved by any particular trading program. One of the limitations of hypothetical performance results is that they are generally prepared with the benefit of hindsight. In addition, hypothetical trading does not involve financial risk, and no hypothetical trading record can completely account for the impact of financial risk in actual trading. For example, the ability to withstand losses or to adhere to a particular trading program in spite of trading losses are material points which can also adversely affect actual trading results. There are numerous other factors related to the markets in general or to the implementation of any specific trading program which cannot be fully accounted for in the preparation of hypothetical performance results and all of which can adversely affect actual trading results.
