I'm seeing significant price discrepancies in price data from Yahoo and Google.
Example is RR.L on 16th October and also 10th January when price drops from north of £11.00 to a low of sub £5.00.
This obviously plays havoc with back testing.
Is anyone seeing poor quality of data from Yahoo and Google. Eoddata.com seems to have the same problem.
Thanks
Robert
