What the early range tells you, and how it gets misused
Published by The Retail Trader · AUG 05, 2026 · Price Action
The high and low formed in the first few minutes of the day are called the opening range. It is a reference that is watched all day — and it is useful as a reference, not as a prediction.
At the open, all the overnight news and all the orders arrive together. The high and low formed after that adjustment are the day's first real agreement.
A break of that range shows that interest remains in that direction; staying inside it all day shows that nobody is winning today.
These points come with it:
• You choose the length of the range, and a different length gives a different signal — this is its biggest overfitting risk.
• On big gap days the opening range is very wide, so the stop is far away too.
• On narrow-range days the breakout often fails.
• This concept works meaningfully only in liquid instruments.
In the first minute of the open the spread is at its widest, so waiting for that range to form is its first rule. Trading on that range before it has formed is a contradiction in itself.
