I am trying to parse a FIX 4.4 AllocationInstruction (J) message, I want to identify whether an allocation is to be average priced. Unable to figure out which tag to use for that.
I've tried searching on https://fiximate.fixtrading.org/ and saw 2 tags AvgPxIndicator (field 819) and TrdType (field 828), none of these are part of FIX 4.4 AllocationInstruction.
