"Market Data - Incremental Refresh" Message

Imported from previous forum

Hi All,

I am a newbie. I am looking for schema and some example of “Market Data - Incremental Refresh”(Msg Type=X) Message. My goal is to find out real time price for all available Spreads. In the Fixionary 2003 I found information on all fields of “Market Data - incremental refresh” Message Type but I don’t have information on Schema and I was not able to find any example of that type of message.
Any help will be appreciated.

Thanks,
Smita
