This program takes in a FIX4.4 message and tells you if there are errors or no errors.
It looks for the required fields only. It ensures checksums are last and are integers. It ensures the body length is correct and is the second field. It ensures the first field indicates the message is of the type FIX4.4. It ensures the third field MsgType is third and finally it looks for the two required fields which are always unencrypted. Those are SenderCompID and TargetCompID.
- BeginString (8= ) - Always First
- BodyLength (9= ) - Always Second
- MsgType (35=) - Always Third
- SenderCompID (49=) - Always Unencrypted
- TargetCompID (56=) - Always Unencrypted
- CheckSum (10=) - Always Last
