It might be more reasonable to hope for a port of Medved QuoteTracker, in that it is free -- you pay a low $7/mo fee to get the ads removed -- and, more important, it accepts hundreds of different data feeds.

OTOH, when I used to trade actively, I had an array of 3 monitors, each 19" or larger, to use it effectively. It's a bit hard to imagine it on a Tablet!
