Opening Range Breakout (ORB)
An opening range breakout uses the high and low of the first few minutes of the trading session as a reference range, then watches for price to move decisively beyond it. This category covers how to identify and structure trades around that pattern — the mechanics, the tradeoffs, and how to practice it before risking real money.
This is one of the few strategies on ScalpClock with a dedicated live tool behind it: the ORB Signal Engine tracks the opening range and flags breakouts automatically, so you can see the concept play out in real time instead of just reading about it.
Frequently Asked Questions
Opening Range Breakout FAQ
What time frame should I use for ORB?
5, 15, and 30 minutes are the most common opening-range lengths. Shorter ranges react faster but are noisier; longer ranges are smoother but give a later signal. 15 minutes is a common middle-ground choice.
Does ORB work for options as well as stocks?
The opening range is defined on the underlying stock's price, but traders commonly use a confirmed breakout to time entries into options contracts on that stock.
Is ORB only relevant right at the market open?
The classic version is specifically about the first minutes of the regular session, when volume and volatility are typically most concentrated, though the same range-then-breakout logic can be applied to other windows.
How is ORB different from other breakout strategies?
General breakout trading can apply to any support or resistance level formed at any time. ORB narrows that idea specifically to the range formed in the first minutes of the session.
