Hi,

I’m not sure I understand what you are asking for.

The presence map (pmap) is a bitmap.
You will find a description of the pmap details in:

http://www.fixprotocol.org/documents/3066/FAST%20Specification%201%20x%201.pdf

FAST doesn’t include a bitmap field type.
There is however a “set” field type define in FAST 1.2:

http://www.fixprotocol.org/documents/4372/FAST%201%202%20Extension%20v10.pdf

These two specs together define the current FAST protocol. We are currently working on a few minor extensions but none of these are related to bitmaps.

Please ask again if this doesn’t answer your question.

Best,
Rolf
