I've been having a problem with bad data appearing in AB (abnormally high 
volume or wrong OHLC) in AB when I perform an "Explore" from the "Automatic 
Analysis" on a large number of symbols (>1500) when I have "wait for backfill" 
checked even for something as simple as filter=C>O.  

Fortunately the bad data points are very easy to identify and seem to occur on 
the same days for the affected symbols and since I haven't been able to resolve 
it, I've sort of learned to live with it (Note, I don't get any bad data in 
QuoteTracker running on the same machine using the same RT data feed so I'm 
pretty sure it's in AB).

Anyway, when I see the bad data, I right click on the "Plug-in Status" area of 
the status bar and do a "Force Backfill" and all the data is correctly filled 
in.  My question is, is there an easier way, either from the menu (so I can 
setup a macro) or better yet, via some code/formula that will  
  1.  Keep all the symbols but delete all the EOD and RT data
  2.  Automatically "Force Backfill" from my RT feed?

If someone has an idea on what's causing the problem in the first place, that 
would be helpful too but I've posted this regarding this problem before and 
haven't seen a solution so I'm guessing I'm a unique case.

I've also tried flushing the DB cache and playing around with different 
database parameters, in-memory cache size, setting up a new database etc.

Thanks.
