2^31 = 2.147 billion. Looks to me like you're maxing out a 32-bit
integer and wrapping into negative numbers.

I haven't run into this but I'd suggest you try changing it to "10".
(NOT 1/10, but 10.) I assume this would divide all volume by 10, so
you should be able to handle volumes up to 21 billion. That should
be enough for the next year or two. :-)
Any historical dates that went past 2.1 billion will be corrupt.
You'll have to get data from somebody who had it set properly to
start with.
