What the opening range is
The opening range is the high and low printed in a defined window after the open, commonly 9:30 to 9:45 AM ET. Those two prices become the day’s first reference levels.
An opening range breakout is a move through that high or low, ideally with volume, rather than a random spike in the first minutes.
How traders use it
The idea is to define the range, wait for a break, and only then look for confirmation from trend, volume, VWAP, or a moving average. Without confirmation, many early breaks fail.
The educational rule set — entries, re-entry, stops, and targets — is part of Premium, not this public overview.
What usually goes wrong
Chasing the first tick through the range without a plan, ignoring relative volume, and fighting the morning sector bias are common mistakes. A clean break that stalls at VWAP or fails back into the range is often a skip, not a force.
Treat the opening range as structure, not a guarantee. If the stock or the tape does not match your rules, the correct action is to wait for the next setup.
