I am using MT4 with a demo server on an 3rd party Broker. I am using a screener indicator on one chart which works fine. When I install the same screener indicator on another chart in MT4, the feeds works fine two. However, on shutting down MT 4 and restarting again I get the No Connection error. This error only happens when I have two instances of the same indicator running on two separate charts, in case of only one instance of the indicator,MT4 connects OK on restart.
What could be the issue and how to solve it?
You should still be able to connect to the broker even if the market is closed.
It may be that the broker is using the weekend for some maintenance?
