Opening range
Definition
The high and low of the first minutes of a session.
Why it matters
Opening range breakouts are common because early volume sets the reference levels other participants trade around.
Example
The first 15 minutes of the RTH session gives a high and low; a break of that range with volume is the basis of the opening range breakout setup.
