It looks like your question about the symbols was answered at http://forums.iqfeed.net/index.cfm?page=topic&topicID=5618
. However, I'd like to add a little bit to it, on how to get the weekly data via TCP/IP connection.
The TCP/IP data has a historical section, described at http://www.iqfeed.net/dev/api/docs/HistoricalviaTCPIP.cfm.
It has a code to retrieve composite weekly datapoints, which is HWX. The syntax of the request is:
All but HWX and the ticker symbol are optional. The other parameters let you specify, respectively, a maximum number of data points; whether you want oldest-to-newest or newest-to-oldest (set DataDirection to 1 for the latter); RequestID (an identifier that will be sent back at the start of each line) and DatapointsPerSend (the number of datapoints that IQConnect.exe will queue before attempting to send across the socket to your app).
