96522My MT4 platform matches with EURGBP M1 data from 1999 forward using the download button built into the history center. I delete all history from all time frames of this currency pair before I download. So it is going to recalculate the data the second time, I download a second time. It seems to wash it a little. I then login into an invalid account and never re-connect again until I decide to update my data. My evaluations are at 90% for EURGBP. I utilize MetaQuotes as the server.
