Closing Order on EMA

I am looking for EA that would close open order when 2 EMA cross over.

Say i have entered daily long order in the middle of daily trend and the EA would automatically close my position when 2 EMA cross over (trend reversal).

same thing for short order.

Any one can help ?

But it is giving an alert, not a close.. maybe you could modify it.
