Yep, I'm using this PremiumData for backtesting on long history and so
can keep it as a local database.
So far I am very happy with the
PremiumData historical data and especially the delisted symbols. I've
wanted this at a reasonable price for a long time and this seems to fit the
bill. I've always worried about survivorship bias in my systems, but
this is showing me that it is not the concern I imagined it to be. And
this has given me a huge amount of out-of-sample data to test over.
The systems have held up well.
Thanks for the picture.

Looks like you found it, you need both

The only issue with local data is
occassionally you must switch to metastock as source or import the
metastock data to get the most up to date prices. But if as you say
you just need a data set for
testing, using local data is definately the
quickest. I do it that way myself when researching & running many
backtests then switch back to metastock data when I need the updated
data.
