How to solve the problem of a big gap in the price chart

 

As you could see from my attached pic, there is no chart(and also no data) from June to September.

Data are just downloaded from mt4's historical center, from "MetaQuotes Software Corp."


How to solve this problem?

 
Did you try to press right click/refresh on that chart?

Thank you Lord,

I tried to refresh, then the gap disappear. But at strategy testing, there are lots of umatched data error.

Then I go to historical center and download data, the gap shows up again! In this case there are no unmatched data error, there are just no testing data in the gap period.

What is happening? this indeed bothers me.

Thanks
