Adding POP-UP alerts and email alerts to an indicator

1. The code is available here https://www.mql5.com/en/code/22186

2. The upward movement is displayed by the green histogram, the downward movement is displayed by the red histogram and Uncertain movement is displayed by the blue histogram. I would like a pop-up sound alert and mobile push notification whenever there is a colour change. It can be turned on or off.

3. I would also like an alert when it reaches the over-bought and over-sold levels.
