Why does FIX show OCEA for Last Market (tag 30) instead of BLUE?
Both UAT and PROD environments use OCEA as the LastMkt value; the LastMkt will not be BLUE.
In FIX sessions, participants may see:
-
Tag 30 (Last Market) = OCEA
-
Tag 49 (SenderCompID) = OCEA
This behavior is expected in both UAT and Production. The LastMkt value will always be OCEA; it will not be reported as BLUE.
No translation or adjustment is required for clients.
