CVO: Cumulative Volume Oscillator allows you to choose between 3 types of oscillators based on volume indicators:
-OBV (On Balance Volume)
-CVD (Cumulative Volume Delta)
-PVT (Price Volume Trend)
Being a volume based oscillator this indicator allows for the detection of divergences between price action and volume, ideal for predicting reversals.
As an oscillator you can choose the length of the fast & slow EMAs, and a signal line is provided for trend following.
