I'm running IQFeed 184.108.40.206. 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 (http://www.iqfeed.net/dev/api%5Cdocs%5CDynamicFieldsets.cfm)
"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)?
