If we have two access points to a market (we suppose that we have a FIX client)
1/ the first access point is for Orders In/Out.
2/ the second is for Market Data,
(Only Market Data - Incremental Refresh and Market Data - Snapshot/Full Refresh messages are allowed in the second access point) or (we can vehicle, for example, news, advertisement…)
In other means, which exactly the messages are allowed, in Market Data access point, which ones, are in Orders Out?

An other question: who are the markets that are using FIX ? and how they define their access points? did they define: an access point for Orders In, an access point for Orders Out and an access point for Feed market?
thank you,
but what I really want to know which are the messages which are considered as feed market, excuse me I know that it would be very obvious but not for me !! since It’s my first experience in a trading protocol!!
Thank you for all.

Hopefully this will help. This shows the FIX 4.2 messages organized by trade lifecycle (pre-trade, orders & executions, post-trade) and categories within each. Our intention is to divide the spec into volumes along these lines when we release FIX 4.3. To answer your question, please refer to "PRE-TRADE", "CATEGORY: MARKET DATA".

I think you will find that it may vary as to how markets implement this. High volume market data is a good candidate for being handled via a separate "channel" than orders and executions.
