Trend Intensity Index Indicator In Zerodha Kite

Trend Intensity Index Formula

Trend Intensity Index indicator was developed by M. H. Pee. This indicator is used to measure the strength of a trend of a sock, ETF index or any other tradable security. The RSI principles of calculation applied to the closing price deviations instead of the closing prices are uses Trend Intensity Index (TII) indicator. In this TII indicator is used to generate trading signals on assumption that the stronger current trend is the more analyzed stock like index, ETF, etc. which will continue moving in the direction of the current trend.

Formula and Calculations of Trend Intensity Index Indicator

The calculation of Trend Intensity Index (TII) indicator which is applying by Relative Strength Index (RSI) principles to the closing price deviations.

Trend Intensity Index Formula

  • Simple Moving Average (SMA) of the closing prices:
    SMA = SMA (Close, n). where n is SMA bar period.
  • Positive and Negative deviation of the closing prices from SMA calculation :
    Dev = Close – SMA
    IF Dev is greater than 0 then posDev equals to Dev.
    IF Dev is less than 0 then negDev equals to abs(Dev) .
  • The total of Positive and Negative deviations for the period is twice smaller than the period used for the SMA calculation :
    1. SDpos = sum(posDev, m).
    2. SDneg = sum(negDev, m).
    3. here, m is period twice smaller than n : m = n/2. If the bar period number (n) is not even then m equals to (n+1)/2.
  • Trend Intensity index :
    TII = 100 * (SDpos) / (SDpos + SDneg).
  • 2nd line or signal line as EMA applied to Trend Intensity Index: Signal Line = EMA(TII, k), where k is bar period of EMA applied to TII.


Like other oscillators, the TII is also bounded between 0 and 100. When the Trend Intensity Index (TII) indicator shows a reading above 50, this indicates a bull trend. When the TII shows a reading below 50, a bear trend is probably present. The TII distances from the 50 level which is the greater the intensity of the current trend. The closer the Trend Intensity Index indicator is to one hundred, the stronger the bull trend. The closer this indicator is to zero, the stronger the bear trend.
