Aha, it is unadjusted.

So which service provider is your data source for unadjusted data? And is this data identical to the Yahoo data that is no longer available? Do we even have a way to confirm this?

Strategy/History.c

It's available in the latest beta.

Finally, check out the Z history editor, which lets you investigate t6 files. (Last time I checked, not t8.) Get it here:
