Post-timed order placement

I was wondering if there are any EAs out there which can place orders at specified times of the day without interference. This would be really helpful to open orders at times when work and news releases collide. for eg. I'm usually working when GBP news is released at 8.30 gmt. Is there an indicator on which i can place the order at 4.00 gmt so that it can be executed at 8.00 gmt??

You dont need anyindicator or EA for this. Althought you could code and EA to place a trade for news for you, just get the EA to make a pending order, or activate when it recieves news.
But anyway if you cant make a trade because you are not there, just make a pending order for a specific time, and close at a specific time.
