/// <summary>
/// The Volume Oscillator measures volume by calculating the difference of a fast and a slow moving average of volume. The Volume Oscillator can provide insight into the strength or weakness of a price trend. A positive value suggests there is enough market support to continue driving price activity in the direction of the current trend. A negative value suggests there is a lack of support, that prices may begin to become stagnant or reverse.
