Implementation Standards

Imported from previous forum

Are there any standards governing implementation details such as TCP/IP port, data formats (like NDR), etc. or is this vendor specific?

The TCP/IP port to use is based upon agreement between the counterparties (doesn’t really affect one’s FIX system as much as their firewall and network configuration). The FIX message data is passed as an ASCII stream and thus low-level issues such as data format representation of numeric types and other primitive data types is not something you have to deal with.
