For completeness of Relative Strength studies, the Relative Strength based on rate of changes (ROC) with weighting is coded and presented as well.
The RS.ROC is similar to the formulation of RS by IBD before rank among all the stocks in the market.
The lookback period is relaxed for customizing. Once you set the total lookback period, representing the 4Q, in the indicator, the other shorter lookback periods will be auto-calculated, namely, 1Q, 2Q, 3Q.
A simple moving average of the RS.ROC is also added for your easier analysis on the trend development of the strength.
