Cumulative RSI

[Alexander.Gettinger]

Original LUA oscillator: viewtopic.php?f=17&t=1340.

The cumulative RSI is intended to be used in cumulative RSI strategy described in Chapter 9 of Trading Strategies That Work by Larry Connors and Cesar Alvarez.

The formula is pretty simple:
CumulativeRSI = SUM(RSI(N), X)

The book recommends to use the small numbers for N and X, such as 2.

This doesn't seem to be Connor's RSI..

Connor's RSI consists of three components:
a. Short term Relative Strength, i.e., RSI(3).
b. Counting consecutive up and down days (streaks) and "normalizing" the data using RSI(streak,2). The result is a bounded, 0-100 indicator.
c. Magnitude of the move (percentage-wise) in relation to previous moves. This is measured using the percentRank() function.


The formula given is:
ConnorsRSI(3,2,100) = [ RSI(Close,3) + RSI(Streak,2) + PercentRank(percentMove,100) ] / 3

Is it possible to code this in Lua?
