What it means
The opening range is the high and low of the first part of a session, for example the first 15 or 30 minutes after the open. An opening range breakout trades a close beyond that range.
A close back inside the range after a break is a failed breakout, which some traders trade the other way.
Why traders use it
The first minutes of a session absorb overnight news and set an initial balance. A decisive move out of it can show the direction participants chose for the session.

How to identify it objectively
- 1Choose the session open and range length (for example 30 minutes) and keep them fixed.
- 2Mark the range high and low.
- 3Breakout: a candle closes beyond the range.
- 4Failure: a close back inside within a few candles.
Bullish use
- 1Close above the opening range high.
- 2Next candles hold above it.
- 3Stop below the range midpoint or low.
Bearish use
- 1Close below the opening range low.
- 2Next candles hold below it.
- 3Stop above the range midpoint or high.
What confirms it
- A strong body on the breakout candle.
- Holding beyond the range for several candles.
- Higher-timeframe bias agrees.
What invalidates it
- A close back inside the range.
- A breakout against a strong higher-timeframe trend.
How a hypothetical setup is built
Entry
On the close of the breakout candle, or a retest of the range edge.
Stop
Inside the range, at its midpoint or opposite side.
Target
A multiple of the range height (for example 1× to 2×).

Historical testing
Not tested on The Tradeskill. ORB is easy to define exactly, which makes it a good first strategy to backtest yourself in replay.
Limitations: when it fails
- Many ranges break both ways on the same day.
- Wide ranges make stops large.
- News at the open can whip both sides.
