This would not be difficult, but I wouldn't want to spend the time, if your purpose is to act on these alerts as trading signals. I presume that you would want an email message when the PSAR reverses (from showing dots under the prices to showing them over the prices and vice-versa).

This simple alert would not be profitable. I know, as I have lost a few thousand dollars and a couple of years trying to make money with a PSAR indicator. I no longer have any use for it.
