Placing order automatically at GMT Midnight

Is there any broker which allows to place order in advance to be executed automatically at GMT Midnight?

I want a broker where i can specify that at GMT Midnight, please purchase/sell the specified quantities at the price prevailing at GMT Midnight?

Thanks for your time in helping me.

You can do this with ANY broker is you have the right software. Make a request in the 'Programming' thread. I'm sure Time-Triggered order software exists. (Prob will even appear in a search)
