This would depend on
your data supplier. It sounds like you're getting free data somewhere. If this
is the case I suspect the contracts are not being back-adjusted so you just have
the actual data with a hiccup in price at each contract rollover. So, I would
not overwrite, unless you know you are getting back-adjusted data in which case
you would have to over-write.
