We use QuickFixC++.

I noticed outgoing FIX message ( IOI ) from our system has empty price value (tag 44) as 44=-nan.

Our system's QuickFix has ValidateFieldsHaveValues as Y ( default value). Is it only for incoming message ? If so, is there any configuration option for validating outgoing message ?

Thanks in advance, Frank

    The value is not truly empty. NaN is a valid value for a [QuickFIX `Price`](https://github.com/quickfix/quickfix/blob/master/src/C%2B%2B/FieldTypes.h#L628) field (defined as a `double`), so the message passes this layer of validation. You may need to inspect your outgoing IOI messages in `ToApp` instead. Or, look into why the price is being set as NaN in the first place. – hunch_hunch Apr 17 '15 at 17:25

    My gut feeling is you use them both ways while creating or receiving. Best would be debug and confirm. – DumbCoder Apr 20 '15 at 08:45
