Hi guys, can someone help me add Alert to the indicator?

Thank you very much.

Currently I am not eligible to pay, if anyone can help me for free, please help me.

I want a message to appear, with audio when the Momentum indicator has a value between 48-52.

Thank you so much.

1.   int counted_bars = IndicatorCounted();
     iCount = Bars - counted_bars - ExtPeriodROC;

   After the first run, counted_bars will be zero, iCount negative, and your for loops do nothing.

2. You should stop using the old event handlers and IndicatorCounted and start using the new ones.
