Hi,

I am trying to generate an alert in Expert Advisor when the following conditions are fulfilled for the 1st time:

Mov(C,3,E)>Mov(C,5,E) AND
Mov(C,5,E)>Mov(C,8,E) AND
Mov(C,8,E)>Mov(C,10,E) AND
Mov(C,10,E)>Mov(C,12,E) AND
Mov(C,12,E)>Mov(C,15,E) AND
Mov(C,15,E)>Mov(C,30,E) AND
Mov(C,30,E)>Mov(C,35,E) AND
Mov(C,35,E)>Mov(C,40,E) AND
Mov(C,40,E)>Mov(C,45,E) AND
Mov(C,45,E)>Mov(C,50,E) AND
Mov(C,50,E)>Mov(C,60,E)

I can get the candles highlighted when the conditions are fulfilled but just can't get to generate an alert when it happens for the first time.

I am a novice when it comes to Metastock or any kind of coding.

PS: The EMAs are part of Guppy system.

Thanks in advance.

You can use the Cross function to identify the first time a condition becomes true (after being not true) but this won't limit the expert advisor firing off an alert with each new tick if the condition remains true. An example of using the cross function would be:

X:=Mov(C,3,E)>Mov(C,5,E) AND
Mov(C,5,E)>Mov(C,8,E) AND
Mov(C,8,E)>Mov(C,10,E) AND
Mov(C,10,E)>Mov(C,12,E) AND
Mov(C,12,E)>Mov(C,15,E) AND
Mov(C,15,E)>Mov(C,30,E) AND
Mov(C,30,E)>Mov(C,35,E) AND
Mov(C,35,E)>Mov(C,40,E) AND
Mov(C,40,E)>Mov(C,45,E) AND
Mov(C,45,E)>Mov(C,50,E) AND
Mov(C,50,E)>Mov(C,60,E);

Cross(X,0.5)

This is exactly what I was looking for . Thanks a million.

Just one question. What is this '0.5'? How did you get it.
