Why the downloaded historical datas are not compltet?

 

Hi,

I want to do a back testing and before I do this I download first the historical datas of USD/EUR of 15min. But as I run the back testing I got error that "...TestGenerator: no history data 'EURUSD15' from 2017.06.01 to 2017.06.08".

In fact, as I open the downloaded historical data sheet, the historical datas from 2017.06.01 to 2017.06.08 are really not there. But strangely the datas before 2017.0527 and after 2017.08.18 are there. Why?

It is related to the broker.

Here is the warning I got as I download the historical data. It seems they are not from my broker.



And one can see from the historical data source. They are from "MetaQuotes Software Corp". I wonder if the other also have such a problem?




And I want to write email to MetaQuotes Software Corp. But I couldn't find their contact email.

Metatrader 4?

It is from MetaQuotes, and the data is fine:


To load the data from MetaQuotes - you should be connected to MetaQuotes demo account:

Are you connected with some broker? So, you are downloading the data of this broker.
Because every broker is having its own data.

 
If you don't have any/partial history, here's how you can get all available from your broker via MT4.
 

Thanks for the reply of your both above. 

Does this mean that when I do real trade, there could be data gaps? If this could happen, that's quite danger, right?
