Evaluating VMA surges is a key element in building a trading system based on volume surges. For instance, a 1-day VMA that protrudes significantly above a 10-day VMA may be indicative of an abnormally high trading activity, which has the potential to lead to changes in the market's prevailing trend. One of our newest indicators is the Percentage Volume Oscillator (PVO). The PVO will assist you in evaluating the magnitude of VMA surges as they occur, thus enabling you to foresee probable changes in an index's prevailing trend. More...

The calculator above help you to determine incidences where the market displayed high PVO values, a reflection of large VMA surges. The higher the value of the PVO, the greater the magnitude of a volume surge. Furthermore, there is usually a positive correlation between the size of a volume surge and the probable market reaction. A trader armed with the following knowledge is well positioned to take advantage of anticipated market moves: (1) Knowing whether a VMA surge is buying or selling; (2) Knowing the PVO value of a particular volume surge; (3) Having a benchmark value against which to compare the current volume surge and its PVO value.

A comparison with previous volume surges that displayed similar magnitudes and PVO values is thus of great benefit.
