Can I use Pepperstones MT4 Webtrader with myfxbook?

I have a Live account with Pepperstone that is already connected with a signal from myfxbook to do automated trading.

For the last 2 years I had the MT4 running on my pc - and the pc was alive 24/7 to be connected for trading.

But now I wondern if it wouldnt be possible to use the MT4 Webtrader for that.

Pepperstone says the MT4 webtrader is cloud based, but the support couldnt tell me if this cloud based MT4 is running 24/7 or not.

If I could use the webtrader with myfxbook and the signal would be copied still I could free my standalone pc from that work. saving me some resources.
