EXTENSION PROPOSAL - Boolean Type Background Several fields in FIX use the datatype Boolean. Encoding these fields in FAST 1.1 requires an entire byte. Introduction A new boolean type in FAST could be used to represent these fields as a single bit in the presence map. The use of booleans in FAST has been brought up several times before and should be reconsidered as an alternative to the MAP INLINE proposal. The boolean type cannot represent boolean fields that are sometimes null. This may be problematic for FIX over FAST implemenations as a Boolean field could be set to 'Y', 'N' or not present at all. Since only a single presence map bit is used, field operators are unnecessary. Examples <boolean name="PreviouslyReported" id="570"/> Wire Representation A single presence map entry would indicate the value of the boolean field.
