Add alert and notification to histogram cross
What you really mean to say, is that you want someone to modify and code it for you for free, right?
Because, "helping", would be you trying to do it yourself and then just requiring some guidance in the case you had some trouble with it.
Ok. i would reword it then. I need someone to help me to modify the code for me for free. If you are willing to. Thank you.

For something like this it is normal to only check on closed bars.
So, for a cross from negative to positive, you check if the histogram's value in the last closed bar was larger than zero
If it was, then check the value for the bar previous to that. If it was smaller than zero, you know that there was a cross and send an alert.

Hi i need help on adding an alert sound and notification to send to phone to this MACD when the histogram bar crosses the zero line to negative/positive.
Can someone please help?
It can be done simply this way. You can arrange the remaining parts according to your wishes.
