I have 2 long term z12 demos on spreadbetting accounts, one with FXCM and the other with Alpari using the MT4 bridge.

I tried the "trade test" script and it opened and closed a sell.

DO I need to run it until I get a buy?

This test was run on the desktop, the test system was on the VPS, but I didn't think that would matter.
