Detailed Description
This indicator computes the True Strength Index (TSI). The True Strength Index is calculated as explained here: https://school.stockcharts.com/doku.php?id=technical_indicators:true_strength_index
Briefly, the calculation has three steps:
- Smooth the momentum and the absolute momentum by getting an EMA of them (typically of period 25)
- Double smooth the momentum and the absolute momentum by getting an EMA of their EMA (typically of period 13)
- The TSI formula itself: divide the double-smoothed momentum over the double-smoothed absolute momentum and multiply by 100
The signal is typically a 7-to-12-EMA of the TSI.
