FIX issue with new order single

Question

I am new to FIX technology and am working on a FIX application. Whenever I send a NewOrderSingle message, I get an error.

I am using the QuickFix engine in C# and creating RequestPlaceOrder objects and filling the required fields. The FIX message in the RequestPlaceOrder is as

8=FIX.4.49=11235=D 1=GtlXXXXXX 11=USD/CHF_2 21=1 38=30 40=2 44=20 54=1 55=USD/CHF 59=0  
60=20120123-03:45:42 207=GTLXXXX 10=069

In the above message, I have not included the header and trailer message since it’s mostly common and appended by QuickFix engine.

56=PFSORDER?45=6?58=Required tag missing?371=14?372=8?373=1?10=151

What's the issue?

Answer 1

You need to send tag 14 (cumqty) as it is required by your counterparty. I am guessing that your counterparty uses it for something so check your rules of engagement; tag 14 is not normally in NOS messages so you may need to add it as a custom tag.

Answer 2

Check your messages for completion on Fiximate.

And pay attention to the tag 371 which mentions which tag is missing or is being referred to.
