The true strength index (TSI) is a technical indicator used in the analysis of financial markets that attempts to show both trend direction and overbought/oversold conditions. It was first published William Blau in 1991. The indicator uses moving averages of the underlying momentum of a financial instrument. Momentum is considered a leading indicator of price movements, and a moving average characteristically lags behind price. The TSI combines these characteristics to create an indication of price and direction more in sync with market turns than either momentum or moving average. (source: wikipedia)

Hello,
The formula you describe in this post is not the same as in the prorealtime tool (predefined indicators).
Could you please show the formula used in prorealtime?
Thanks
I think if you substitute Momentum for ROC in the code you get the tool values.
Hello Nicholas I confirm you that the formula it is not the same. Could you please give me a link where I can find the predifined code of True Strenght Index? I need to it to take as example to create the True Directional Index (another William Blau indicator)
I confirm too that the formula given above differs from the predefined TSI. Why this missmatch?
Bonjour.
L’indicateur fonctionne remarquablement.
Je n’arrive cependant pas à l’intégrer dans une stratégie “croisement TSI / TMA”. Pourriez-vous m’indiquer comment faire ?
Cordialement
