Re MyTrack: It's my primary service, too, and generally very good with nifty features. But note that it, too, is giving lots of bad data today (mostly regarding volume).
Comparing its quotes to other services today (incl. Bloomberg & Yahoo), many of its numbers have been right but many are also far off the mark (volumes are wrong for all kinds of things ranging from AAC to MSFT, plus many OTCC stocks -- although the prices seem more current, for some reason).
They promise they're working on the problem. But if you're relying on MyTrack's numbers today, should double-check elsewhere to avoid acting on bad info...
