Moving Average Cross Alert Study for Think or Swim

Here’s a script that shows how to trigger an alert on a moving average crossover, but only after the bar that caused a crossover has completed. I have an arrow plotted intrabar if the averages cross, and it disappears if they uncross. This same thing can happen to alerts based on the crossover, giving you an alert that is later invalidated. The way around it is to have the alert look one bar back, so it won’t trigger until the first tick after a crossover bar is finished.

The script is called “MACrossover_w_AlertsSTUDY.ts”, and is free at my Google site under
“Released Thinkscript Studies”.

    You change average() to expmovingavg() basically.

    I love the idea of triggering an alert. Would it be possible to make it text my cell phone too?

  5. Prospectus Says:

    If you use the marketwatch tab and have it email on the alert triggering, then yes it can text your phone.

    I understand the system is not setup for this functionality (custom indicator email alerts yet, well so TOS tell me.

    Hi Thank you got yr MA crossover study working except for notification to my email. The study is working fine in “Messages” located btw “Home screen” and “support chat” and sound also working perfectly

    The email notification function is working fine in the create alert function e g the drop down function one gets while in charts to say create alert for price movement above or below a specific price.

    So at a loss as to how to get email notification working within your study. Would appreciate help and TIA
