I need to modify Laguerre Indicator

Hi coders and programmers. I need to modify the attached indicator. I just want an alert when a new dot (different dot color) appears when line goes up or down. I need with the alert the pair where the signal comes from and a message. The indicator has an alert but it triggers many times like crazy and the alert is only when the dots are on the bands but not when a new one (different color) comes.

Thanks
