Evaluating the Magnitude of Volume Moving Average (VMA) Surges
Daily VMA Surge Evaluation - Volume Oscillator Calculator
Evaluating VMA surges is a key element of our volume analysis methodology. For instance, a 1-day VMA that protrudes significantly above its 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. Generally speaking, the more extended the duration of the VMA surge, the stronger the potential that the ensuing trend reversal may be significant.
Note: Please, keep in mind that slow and fast VMA period setting is defined by trading days. For instance 5 trading days are equal 7 calendar days (1 week).
