Repeated Alarm sound until off ~
paul.seldon:
See https://www.mql5.com/en/forum/148934 (though note that the use of PlaySoundA and PlaySoundW now needs to be swapped over in build 600+).
I would like to create the alarm that sound repeatedly until off when RSI is value is in the user-specified range.

I would like to create the alarm that sound repeatedly until off when RSI is value is in the user-specified range.
Can you help me out, I'm expecting the website to take a look at. I am not asking to solve. I am asking for help to point out ~
Thanks in advance ~
