Larry,
Hello, this is Gary with DTN IQFeed API Support. I apologize for the delay in responding.
Here's the documentation about the Market Summary info:
http://www.iqfeed.net/dev/api/docs/docsBeta/MarketSummaryviaTCPIP.cfmTo summarize, there are three types of requests: EDS, FDS, and 5MS. Each allows you to retrieve a market summary, based on a commodity type and exchange. EDS and FDS are daily, while 5MS is a five minute snapshot.
The syntax is:
EDS,Security Type,Group ID,Date
For example:
EDS,1,5,20190903
would return a daily market summary for Equities (code 1) on the NASDAQ exchange (code 5) for September 3, 2019.
You can view a list of the codes with the following commands (which are also listed at
