Marty, Peter,
I found Nasdaq intraday volume plotted in marketvolume.com. It seems that it is used to create their Nasdaq MV indicator. Their website says "We track EVERY stock listed on the NASDAQ exchange and combine their volumes on a minute-by-minute basis....." So now at least I know it can be done. It seems relatively easy, and a core market indicator (vs some of the exotic indicators created by using price and/or volume). I wonder why all intraday charting software does not do it?
Thanks for the link
