For reference purposes, the Vertex indicator is a repainter and was update on TSD some time ago with convenient features.

I'll upload it here in case anyone needs it or can improve on it.

This particular version includes (newer drop down box) Multi-timeframe + Interpolation, Automatic next timeframe MTF choice, Arrows on Overbought/Oversold, Arrows on Extreme Overbought/Oversold, Alerts and more.
