Adding a pop up message box and sound alert

[[Deleted]]

Hi,

May i inquire how can i add a pop up message box with a sound alert indicating the time,the currency pair and the colour.

The alert will sound and text box will pop up only at end of the bar once.

The condition for the alert is when the candle change to Red or White or Magenta.

Currently when i add in the alert,the sound will keep on repeating non-stop.

I have attached a pre-modified version so here.

Would appreciate it if someone could help answer my question.

Thanks
