treliff, The reason I want to plot the "bid" of vol-nasd-nasdaq-ind is that is where IB stores the Nasdaq up volume information. The down volume information is stored in the "ask" location. If you subtract the "bid" for the "ask" you get the real time spread in the Nasdaq volume. What I would like to do is plot the Nasdaq volume spread.
