We are coding to accept FIX orders.
Currently we take a 3 character term ID with a 4-digit seq#, followed by a date.

In order for us to take a unique order number from anyone, Tag 11 ClOrdID, does anyone have any feedback as to what should be the maximum number of characters we should plan for?

Thanks~

Maura,
There is currently no limitation on the content or length of any reference field in FIX. However, ISO 15022 currently has strict limitations and settlement of a trade often involves mapping ClOrdID and OrderID to Fedwire or SWIFT - both of which adhere to that standard. To be interoperable you should limit the content to alphanumerics, i.e. no spaces or graphics, with a maximum length of 16 characters.
