Indicator alert

[Tekunda]

Is there a way to set a custom alert, e.g. if an indicator behaves in a certain way, for example a simple, primitive EMA crossing?
Sometimes big moves in Forex start at night in my time zone and the cross alert would wake me up if such a a move is about to occur.
So I could get up and have a short look at the chart to decide if I should enter a trade or not. (Of course EMA crosses alone are not worth a lot, but they would alert me that a move could begin)

That can be easily done with an efs. There are literally hundreds of example from the simplest to the more complex available in this Bulletin Board.
