What are the different Open types in Market Profile?

The first auction of the day is noted in the Open.

The A period is the first 30 minutes of the session and in Market Profile we chalk the first 30 minutes on our charts as the A period.

The A period holds more weight than any other period during the day. It is identified with the presence of the longer time frame players who move swiftly to drive prices during the A period.

The Open of this A period is a study in itself and a good understanding of this is often a difference between being on the right side of the market or not.

There are various types of open:

OAIR- Open Auction In Range
