How to add alerts

I want to know that how can I add alerts to my charting softwere where there is crossover of 2 lines. Or any criteria is filled, then I want that an alert sound is created so that I know if I am off the screen.

 

could do w/tradelink if you used email instead of a sound

 

Not actually because I want to hear the sound where a crossover happen of the 2 EMA. The real purpose is that I hear the sound if I am away from screen.

 

ok i understand but if you email your phone you will hear the alert on your phone when you're away from screen.

do what you want, just my .02
