Can I connect demo and real at the same time?

Yes you can. You can create 2 or more connections, and switch between them in the Chart Trader list of accounts. Please note that in case of connecting several accounts, the supplier of quotes should be only 1 of them, otherwise the quotes coming from different sources will be duplicated and distort the real situation. To do this, in the connection window of quotes, you need to leave marked checkbox only near the connection you need.
