Hi,
Yes, I have been tracking the exchanges that are given free (American) and the historic data ( previous month) changes on an almost daily basis, particularly OTCBB. On some downloads data from 20 days ago is different on five downloads taken on consecutive days.
Missing symbols, changed symbols, volumes given are zeros, interspersed characters...
I e-mailed EODDATA about data quality and they asked for proof...duly sent....since then no response.
However, data was especially bad in May when they messed around with their database. It has improved a little in June.
I would be grateful if some T2W member would post another source of data...
