You said you want to write an ECN from scratch.
Lets take the case of a pure FIX ECN supporting FIX trading on a single version=FIX.4.4 for Commodities (what you mentioned as your need).
What is the Technology platform you plan to use? Since I am a FIX-Java programmer, I have been using
Graphic User Interface = Swing
FIX Connectivity = TCP Sockets
Persistence = File I/O and/or JDBC
Language = Java
XML handling for FIXML = Java XML Parsers
Distributed programming = RMI
The following are the logical components of the ECN
Client Connection handler - The FIX Engine - does FIX messaging
Trade Execution Engine - Crosses client orders which enter the order book
You have to define a protocol between your FIX engine and the Trade Execution Engine to handle FIX Order state change matrices.
One point you need to note is that even though all your business messages would use FIXML over ^35=n^ (XML_non_FIX), your Session would be ^Tag=Value^
Regards,
K. Mahesh
