Thanks Glenn for the head ups about Z3. (Can you show me the post? Can't find it... )
The manual says that most strategies including Z1/Z2 will start with some loosing trades. So i'am not concearned at all.

@swingtraderkk: You get an VPS with Microsft Server 2008 operating system. You can do whatever you would do with your local computer. But remember the RAM ist only 640MB. At the moment i have Zorro and one MT$ instance running. MT4 runs only cause of updating my MT4i account.
