Updating MT4 price historical data

New comment
 

Hi everyone,

I can't manage to update my price history in MT4. When I run an EA in 2005 for instance, I get an error because M5 data isn't available for this period. So, I've downloaded some M1 (1 minute) files for 2005 and 2006 on the Alpari website and imported them in MT4. I noticed that the whole history hasn't been saved. But when I run my EA, I still get the same error message. So, my question is : must I manually import M5 data, or can MT4 generate M5 data from M1 data by itself ? I can't find any site or tutorial explaining correctly price update in MT4.

Thanks in advance,

Mark

 
 

Thanks so much, codersguru, that's exactly what I was looking for !

Now, my EA finds its needed M5 data.

I wonder why this great tutorial doesn't appear in MT4 standard website.

Thanks again and have a nice day,

Mark
