TSI: True Strength Index
A doubly smoothed momentum oscillator that shows the trend's strength with little noise.
La idea en pocas palabras
The candle-to-candle change is smoothed twice with EMAs and divided by the equally smoothed size of the changes, giving a calm line between −100 and +100.
Cómo se calcula
Smooth the price change with EMA(25) then EMA(13); do the same with the absolute change; divide and multiply by 100. The signal line is an EMA(13) of TSI.
TSI = 100 × EMA(EMA(Δclose, 25), 13) ÷ EMA(EMA(|Δclose|, 25), 13)
Signal = EMA(TSI, 13)Cómo usarlo
- TSI crossing its signal line.
- Zero line: above it buyers dominate.
Sacar conclusiones
- Readings beyond ±25 are often called strong; the exact levels vary by ticker.
Ejemplo
EURUSD daily: TSI crosses above its signal line at −18 after a long decline; a first sign that selling pressure is fading.
Los precios de los ejemplos son ilustrativos.
Ten cuidado con
- Double smoothing means late signals at sharp turns.
