> FPL has reserved all tag numbers 40,000 and above for future use. Upto what number should others not use? Million / Billion / ... ? Since TagNum is of Base type int and I could not find any minimum / maximum size definitions, is there a limit on the maximum tag number that can be used in FIX messages? For example can tag number 999999 be used in a FIX message ? I do not see any restriction because FIXProtocol is Strings exchanged on TCP so any length integer number can be transmitted subject to parsing capabilities of systems at both sides. Has using decimal tag numbers like 123.45=Value^ been considered? Has using alphabetic tags like SECTYP=Value^ been considered? > The Global Technical Committee Governance Board had met to discuss the > issue of user defined tags and the lack of available tag numbers for > registration, as raised by this thread: > http://fixprotocol.org/discuss/read/e23eb3de > > The GTCGov is proposing the follow short term solution while we work on > a long term policy regarding user defined tags.
