Indicators: Random Walk Index - JMA Smoothed

 

Random Walk Index - JMA Smoothed:

The Random Walk Index (RWI) is a technical indicator that attempts to determine if a stock's price movement is of random nature or a result of a statistically significant trend.

The Random Walk Index attempts to determine when the market is in a strong uptrend or downtrend by measuring price ranges over N and how it differs from what would be expected by a random walk (randomly going up or down). The greater the range suggests a stronger trend. The RWI states that the shortest distance between two points is a straight line and the further prices stray from a straight line, implies the market is choppy and random in nature.


Random Walk Index Formula

The Random Walk Index determines if a security is in an uptrend or downtrend. For each period the RWI is computed by calculating the maximum of the following values for high periods:

(HI - LO.n) / (ATR.1(n) * SQRT(n))

In order to avoid the too many signals that the regular Random Walk Index tends to produce, this version is using JMA for smoothing which significantly lessens the number of false signals.
