[Quickfix-users] Difference between Initiator and acceptor ?

[Ben S. <bxs...@ya...>]

As far as I read a FIX application can be either implemented as an acceptor or an initiator.

What is the difference ?

I assume acceptor waits on incoming FIX msgs whereas initiator sends FIX msgs.
But what if a FIX app should receive AND send FIX applications?

Furthermore I am wordering wether an acceptor must be started BEFORE the initiator part 
starts sending FIX msgs. What happens when the initiator is started BEFORE the acceptor?
