Hi, I appreciate the response. Where can I lay my hands on Alpari M1 data - or are this via the 'History Center' in the usual way??? I have installed several MT 'flavours' already (IBFX, WCH,and Aleccohfx) and all their price data produce identical backtests for me. Also, I was under the impression that since Metaquotes removed the 'Recalculate' option, it was no longer possible to use third-party data - is this true?
I also remember reading that Metaquotes' data was derived from various sources. The only way I could see the results we witness is if the majority of the data is somehow poorly 'fabricated' (something blatantly exploitable, in the M1 interpolated tick data), up until Sept-Oct 2006, and then MT downloads and stitches on something akin to 'real' price data up to the present date. Just look at Metatraders 1999 EURCHF data and it is clear that this could not possibly from a 'real' price feed...
EDIT: - Just installed the Alpari MT and did a backtest. As can be seen from the results, the results are virtually identical - therefore, so is the price data...
