Do I need to leave MetaTrader open to receive Signals?

 

I'm a little new to all of this currency trading. If I subscribe to a signal, do I have to leave MetaTrader up and running on my computer to receive signals? Or, does the signal provider communicate directly with my Broker?

Thanks!

Yes to the first, no to the second.
 
Yes you need to leave it on ,unless you get a VPS , or double check with broker some brokers offer the vps server for free
