A Volume Moving Average (VMA) is like any simple moving average, except that we apply it to volume rather than to price data. By smoothing out individual surges in the volume activity of an index, VMAs allow you to see the general trends and volume patterns of an index. VMAs are an important tool used in volume analytics and we have incorporated them into our JavaVolume™ charts. These charts allow you to determine, whether institutional and professional traders are currently Selling or Buying. This knowledge can help you make accurate predictions about the short-, mid-, and long-term trends of the index.
