**MT4 History Centre**

 
Hi! Hope everyone is doing well!

I have couple of questions:

In MT4:

1. When I double click for example in XAUUSD D1, this data is downloaded from trade server, right?
2. When I select Download, this gives you an alert saying that data will be downloaded from MetaQuotes, so, data is overrided with MetaQuotes instead of trade server.. right?
3. Which data should I be using then to backtest? MetaQuotes or trade server...

If anyone have answers to any of this questions will be really appreciated! Thanks everyone!

The article provides the results of testing a simple trading strategy in three modes: "1 minute OHLC", "Every tick" and "Every tick based on real ticks" using actual historical data.
 
  1. Why did you post your MT4 question in the MT5 General section (a miscellaneous catch-all category) instead of the MQL4 section, (bottom of the Root page)?

    Next time, post in the correct place. I have moved this thread.

  2. The download is always from MetaQuotes, overwriting your broker's data.

  3. On MT4: if you don't have any history, here's how you can get all available from your broker.

    1. Most brokers only have 32 or 65K bars of history per timeframe. That's 45 days of M1, 2.5 years on M15, etc.
