Initial Balance (IB)

Trader's Glossary · Profile and auction

Initial Balance (IB)

Definition. The price range of the first hour of the regular session: 9:30–10:30 AM New York time (usually 15:30–16:30 in Warsaw).

How it works

The first hour sets the day's initial range. Its width, and whether the market extends it later, tells you about the activity of longer-horizon participants. IB extensions are multiples of its width projected above and below.

Example

A narrow IB followed by a clear break in one direction often accompanies wider-range days. A wide IB more often means a day traded within it.

What to watch out for

These are tendencies, not rules. In the clock-change weeks the IB falls an hour earlier in European time.
