IBH

The Initial Balance (IB) is a Market Profile concept.

The IB is the Range established from the first two Brackets of a Market Profile. These two brackets are usually the first hour of trading and as such the IB is usually the area from the Low to the High from the first hour.

The IB is monitored as a break-out area for Range Extension traders.

The IB High is also seen as an area of resistance and the IB Low as an area of support until it is broken.
