Alert on Oscillator cross over

[staiton]

Could someone please help in assisting me in writing the alert language for a text and sound alert when the following attached Oscillator crosses the 0 line from up to down and vice versa.

Thank you.

Open the efs with the Editor and add the following block of code just above the return statement

if(getBarState()==BARSTATE_NEWBAR){
        if(xOsc.getValue(-2)<0 && xOsc.getValue(-1)>0 ||
           xOsc.getValue(-2)>0 && xOsc.getValue(-1)<0){
               Alert.playSound("ding.wav");
               Alert.addToList(getSymbol(),"Crossing 0",Color.black,Color.red);
        }
    } 

This will trigger a sound and a popup alert when the oscillator has crossed the 0 line on a completed bar.
If you intend to run the efs using an external interval (ie an interval that is different from the one being charted) then in the block of code shown above replace

if(getBarState()==BARSTATE_NEWBAR){ 

with

if(getBarStateInterval(Interval+"")==BARSTATE_NEWBAR){ 

which will ensure that the condition is evaluated only on a new bar of the external interval
