Some notes from his book:
- A buy is indicated when the oscillator is below the green line but greater than yesterday’s value.
A sell is indicated when the oscillator is above the red line but less than yesterday’s value.
- The start of a short term up move is signaled by SVAPO when it turns up from below the lower standard
deviation boundary. The same is valid for a short term down move when SVAPO turns down from above the
upper standard deviation boundary.
- Medium term turning points in an up or downtrend are mostly announced with a divergence between price and
SVAPO. In a medium term uptrend, SVAPO will generally continue to move above the 0-reference line.
Vervroot sometimes uses this with his modified %B oscillator (https://www.tradingview.com/v/sDPe1PDd/).

Now an image with the LazyBear COG a bit changed by me:) showing it is working also visually much better with it. The price making a dbl.top and the second top is below the red band also looking at the SVAPO position being in oversold teritory could lead to the conclusion that a distribution is coming. The AAPL price at the moment shows a bullish moment but the SVAPO shows a weakening of the recent impulse move. I would have liked the COG to have possibility of offsetting the bands 2-4 levels up and down.
