True Strength Index (TSI)
This is the same as the SMI Ergodic Indicator.
Template (v17+)
XAVG(XAVG(C - C1, s), l) / XAVG(XAVG(ABS(C - C1), s), l)
Where s is the short period.
Where l is the long period.
Example
The following is the formula for a TSI3,9.
XAVG(XAVG(C - C1, 3), 9) / XAVG(XAVG(ABS(C - C1), 3), 9)

Bruce,
Please help me understand the above template.
First the price change is calculated ie. C-C1
The way the above is written it looks like the short period smoothing is done before the long period smoothing. Stockcharts.com has the long period first, then the short period.
Double Smoothed PC
PC = Current Price less Prior Price
First Smoothing = 25-period EMA of PC
Second Smoothing = 13-period EMA of 25-period EMA of PC
Double Smoothed Absolute PC
Absolute Price Change |PC| = Absolute Value of Current Price less Prior Price
First Smoothing = 25-period EMA of |PC|
Second Smoothing = 13-period EMA of 25-period EMA of |PC|
What am I getting wrong here?
Thank you,
Don

The order of the smoothing doesn't matter.
XAVG(XAVGC13, 26) = XAVG(XAVGC26, 13)
