Shutting down the computer - EA

Hello,

Is there any EA that would shut down computer when there have no trades/orders left?

fe. It scans terminal at given hour - when there are some active orders/trades it lets them run, in other case it shuts down the computer.

I have not done this but it looks like it would work - ShellExecute or something similar.
