thanks all, we can work around this but I do feel this is not ideal. One of the main wins with OSI (at least I feel) is that everyone will now have a unique identifier to communicate with. if each company/app needs to derive it on the fly, the room for error and maintenane is great. I personally think its better to simply pass the full value in tag 44 and specific it in tag 22 > Tayloe Draughon, GDC Co-chair had us prepare this document to assist hte > industry: http://fixprotocol.org/documents/4213/FIXImplementationGuide_- > USOptionsSymbology_v1.pdf > > Regarding using 48 for the underlying security symbol - I have not seen > that used widely for US listed derivatives markets. > > > And of course MaturityDay(205) will also be required to identify the > > option.
