Could you download my simple yet profitable EMA_CROSS and tell me what's the MST results on his machine?
Note:
The data you getting from the broker server while you are running your demo account is filled with gaps and missing a lot of real data. You can't relay on this data in your strategy testing. So you have to download a complete history data and import it to MetaTrader to have the opportunity to get more accurate results.
You need to have a complete data for all the timeframes available in MetaTrader (1 minute, 5 minutes, 15 minutes, 30 minutes, etc). But if you can get a
complete 1 minute data it will be easy to use the
Period_Converter script shipped with MetaTrader to convert the 1 minute data to all the other timeframes data.
The free and complete (from 16/06/2004 up-to-date) 1 minute data can be downloaded from Alpari Databank by following this link:
