Hi Jayson,
Thanks for that. I checked out the manual on the purity tool. I see it
allows to detect missing/extra quotes, possible splits, invalid OHLC

I would have thought I would have picked up something wrong when I
ran the "Explore" and checked out the values for the particular day.
Anyway I'll give it a go. Thanks.
Cheers Glenn
