Module 3 · Lesson 4 of 7

The Opening Range & the ORB

By the end, you can explain the opening range as a level, and why the ORB is about acceptance, not 'buy the line'.

Mental model

The first argument of the day. The opening range is buyers and sellers staking out their positions in the first few minutes. The high and low of that argument become the lines everyone watches next.

Core explanation

The first several minutes (often the first 15) define the opening range — the opening auction. Its high and low become key intraday levels.

ORB is not 'buy the line'

The Opening Range Breakout is not a rule to buy the moment price crosses the range high. It's watching whether the breakout price is accepted or rejected — exactly the skill from Module 1. A break that's rejected is a trap; a break that's accepted is a move.

You are not trading the breakout; you are trading acceptance or rejection.

Beginner vs professional

Beginner thought

“Price crossed the opening-range high — buy!”

Professional thought

“Price broke the opening-range high. Now I watch whether it's accepted above or rejected back inside before doing anything.”

Price broke above the opening-range high (dashed line). Watch what the candles after the break do — that's your evidence.

Practice drill

In the drill, judge acceptance vs rejection on both breaks. Then, on a live chart, mark the opening range and watch one break resolve.
