[Probably OT] MT4 history center and period converter.

I need to backtest some EA so I downloaded the correct M1 data from Alpari history center.

Now I should convert it to H1/H4 and so on, to use the correct data to backtest the EA.

I have readen several way to convert the M1 to H4 (period converter.mq4 and so on) but no one seems to work.

Do you know how this work?

The strategy tester should do this automatically.

mm not really.. there are a lot of sites and documents that explains the importance of correct data from your broker.

and they also explain how to convert the M1 to the other TF but it's pretty complicated and I'm not english so... I have some problem :|

the strategy tester doesn't actually look at one specific candle. it looks at what price the currency was during a specified range of time. whether that is a minute chart, four hour chart or month chart. for the open it takes the first price in that range, for the high it takes the maximum price in the range, for the low it takes the minimum price for the range and for the close it takes the last price in the range. because of this, you don't need to convert to any period. it will be the exact same thing, just with more work involved.
