Volume Oscillator

The Volume Oscillator (VO) identifies trends in volume using a two moving average system.

The Volume Oscillator measures the difference between a faster and slower moving average (MA).

  • If the fast MA is above the slow MA the oscillator will be positive.
  • If the fast MA is below the slow MA then the oscillator will be negative.
  • The Volume Oscillator will be zero when the two MA's cross.

Trading Signals

  • Rising volume (positive VO) signals a strong trend.
  • Falling volume (negative VO) indicates trend weakness.
