True Strength Index - September Active Trader Magazine

[Michael Harris <hicap92fs@xxxxxxxxx>]

Does anyone have TS2K code for the True Strength Index, as described in
the September issue of Active Trader Magazine?

The code as presented in the article is:

TSI(close,r,s) = 100*EMA(EMA(mtm,r),s)/EMA(EMA(|mtm|,r),s)

where mtm = closetoday - closeyesterday

EMA(mtm,r) = exponential moving average of mtm with period length = r

EMA(EMA(mtm,r),s) = exponential moving average of EMA(mtm,r)
with period length = s

 |mtm| = absolute value of mtm

 r = 25, s = 13

Thanks in advance.
