Here's a "nice model of volume" with reversal signals in arrows and current trend painted as color candles.

Really nice script! Hope to see more like this one added to Warehouse which uses volume to analyse for reversals.
Thanks@BenTen

Can audio alerts be added for the signals?

 

[BenTen]

@zeek Add this to the end of your script:

# Alerts
Alert(pUp, " ", Alert.Bar, Sound.Chimes);
Alert(pDown, " ", Alert.Bar, Sound.Bell);

@BenTen does it repaint?

 

[zeek]

No, it does not repaint.
