Hi Jerry,
This is the situation where multiple MT would help. For example, I can two QT's, one for stocks, one for futures, I have multiple charts open for each instance. I can minimize stock instance so all charts and portfolio are cleared off my screen, or minimize futures instances. It is difficult to minimize a set of charts & watchlist with ONE Click under MT now unless there is a group function where I can minimize a set of charts and watchlist at once.
