Not exactly sure what you're wanting here, but I'll take a stab at it...
* If done thru DTNIQ, I'd guess you'd have to manually(or through automated workspaces) pop up individual T&S(Time&Sale) windows, select tick data, etc, and fire 'em up for each symbol. If you have a large watchlist, this could be many T&S windows. You may have these windows open 'live' during the day, so that you can track current info through the watchlist, and recent/all tick data through each T&S window. Very handy way to go. You could also save that data to disk(say, in .csv input to be used by Excel or some other app).
* Something that may work better if you want to retrieve lots of data would be QCollector for DTNIQ, which is one of the partner apps listed elsewhere on this site.
http://www.mechtrading.com/qcollector/dtn/index.htmThis app allows you to code up a job that will retrieve historical tick(and other types) of data, using IQFeed(the actual feed used by DTNIQ). Among many things you can set on the job are the symbol, and date range for what you want. More than one format in which to retrieve the data, which can be used in many ways, such as input to Excel. I have some routines that build jobs to retrieve tick data in .csv format. I usually run the job(s) offshift/weekends, as during prime time, DTNIQ limits you to the last 8-10(I think) day's worth of data. Offshift, you can retrieve up to 30 day's data, or any excerpt of that you want. Worth a look...
