The better volume is a great indicator. I have made the following observations as a addition to the already existing PDF file

- White/Red
A combination of reversal signals from other indicators and an occurrence of white and red candles (only in this order, important!!! The other way around, the white candle invalidates the red one again) in the Better Volume are a good signal for an incipient upward movement. Especially when other indicators are already in OS zone this can be a strong signal. - Red/White
In combination with reversal tendencies in other indicators in short direction, these speak for a beginning downward movement. Again, the signal is even stronger when other indicators are already in OB zone. - White
White candles occurring alone speak in combination with other indicators (for example with the HAOS) for a reversal signal in both directions. - Green
Green candles indicate a weakening or turning trend. - Yellow
Yellow candles often appear at the end of corrections. Afterwards, the previous movement usually continues.
