[Quickfix-users] Conditionally required Field

[Joaquín G. <j.g...@ra...>]

Hi All,

My quickfix engine is rejecting fill messages from my broker because  
of a missing optional field.

This particular field is the contract maturity, which is not needed  
for stocks. In fact, I am not sending this field when I place the order.

Why a message is rejected when it's missing an optional field and it  
is not needed?

Thank you.
