Who is the Default Broker for the MT5 downloaded here?

 

I downloaded MT5 from mql5.com and its has live feeds.

I am using it for practicing demo trading and strategy testing.

My questions are:

1. Is there is a default broker on the MT5?

2. Where does it get all the live feeds from?

3. Are the feeds and historical data dependable?

My questions are:

1. Is there is a default broker on the MT5?

         . There is nothing called default broker!

2. Where does it get all the live feeds from?

         . Not from the broker for sure, maybe from banks, market makers, or some provider.

3. Are the feeds and historical data dependable? 

         . I think yes
