PPO Divergence Alerts

This is a pretty straightforward script that adds alerts to Pekipek's excellent PPO Divergence indicator and changes the visuals a bit. You can have the alerts fire on these events:

Purple Circle (bullish signal)
Orange Circle (bearish signal)
Green Dot (High Point)
Red Dot (Low Point)

I use this on daily Forex charts to get alerts when purple or orange dots show. As you can see, it catches a lot of big moves, some of which can give insane returns if you're 200x leveraged on the likes of 1Broker.com. In regards to reducing false signals, I'm getting good results with a Williams %R but would love to hear any suggestions.

Edit: Oops. Box #6 in the example should be yellow, not purple.
