I'm running IQFeed I'm asking for these dynamic fields via TCP/IP:

Symbol,Last,Total Volume,Incremental Volume,High,Low,Bid,Ask,Last Trade Time,Open,Close,Previous Day Volume

The dynamic field documentation ( says:

"The dynamic fieldsets only apply to update messages ("Q" messages) received in Level 1 streaming data."

I'm now getting a summary message that looks like it contains only the fields I requested:


As far as I'm concerned, it's great if the Summary/'P' messages only send me those fields. But is that the way it's supposed to be (i.e., the documentation is incorrect)?

It should have been the way it was described in the documentation.

The dynamic fieldsets only apply to update messages ("Q" messages) received in Level 1 streaming data."

It will be fixed in the next version.
