RS_VA_EMA

Description

The Relative Strength Volume-Adjusted Exponential Moving Average (RS VA EMA) is a technical indicator proposed by Vitali Apirine to help identify trends. Its calculation is similar to that of the original EMA, however, the multiplier used in the formula is adjusted for the relative strength of volume.

The strength of volume is calculated as the difference between positive and negative volume flows. Volume flow is positive when the specified price is higher than the prior price; it is negative when the specified price is lower than the prior price. 

Strength of volume is calculated using the following formula: 

where: 

  • PV is the EMA of the positive volume for the specified time period.
  • NV is the EMA of the negative volume for the specified time period. 

Relative Strength Volume-Adjusted Exponential Moving Average is calculated using the following formula:

where: 

  • MA is the current RS VA EMA.
  • MA[-1] is the prior RS VA EMA.
  • α is a multiplier factor equal to 2/ (length + 1).
  • Mlt is a user-defined multiplier.
