Simple EA or script needed

 
Hello, I'm looking for an EA or script that would be able to open buy order if the price will be bellow certain level and only on specific time, example open buy when price is below 1.50008 at 11:00, and be valid only at this time for maybe 10 or 15 seconds. So this is like pending order with expire time modification, Hope someone already have it or is able to code similar system, I would really appreciate it, Thanks.
