Module 2 — Market structure & timing

Why the first hour behaves differently

6 minute read

In plain English

Overnight news, delayed orders and repositioning all arrive at once at the open, so volume and range are usually at their highest.

Why it matters

More movement means more opportunity and more cost. Spreads widen and stops are hit more easily.

Example

A ticker's average 30-minute range at 9:45 can be three times its range at 1:00pm.

Try this

Compare the first 30 minutes of volume with the midday hours on any active name.

Common mistake

Using midday position sizes during the open.

What this does not mean

The open being active does not mean it is the best time for you to trade.
