Anyone know any indicator that can alert if 2 MA crosses each other?

hello, fellow programmer.
I have no programming skill
so i need your knowledge if you have any indicators that give alert if 2 MA crosses each other. For example if MA 20 and MA 50 crosses it will make a sound. If you have that indicator or know any other reference to this kind of indi, it will be helpful if you want to tell me

Thanks a lot.

Here it is, hope it helps.

Good luck
