so my question still remains..if engine identifies it as an application bound message and it hands it over to the trading app,then will the FIX engine be blocked i.e. it won't accept any more messages till the trading app finishes its processing of the message? wouldn't this be a serious performance issue. > FIX messages are accepted and processed sequentially (Ordered Message > Processing), but keep in mind that "processing" can mean different > things for different messages. > > I see the architecture of FIX applications logically as two tier > > Tier 1 - FIX Engine - transports business data without understanding the > meaning of data. > > Tier 2 - Trading Application - produces and consumes business data > without understanding how the data is moved. > > FIX Engine will accept messages and apply Session level validation.
