True Strength Index (TSI) 4 *
Exported using NT Version 7.0.1000.30

The True Strength Index was developed by William Blau and published in his book "Momentum, Direction and Divergence". This version of the TSI is an enhanced version of the NinjaTrader default indicator. It comes with the following improvements:

Momentum period: The original version of the indicator uses the price difference between the current and the prior close, which is the 1-period momentum. The updated version of the indicator also allows for selecting a momentum period greater than 1.

Triple Smoothing: The standard version of the indicator comes with double smoothing for momentum and absolute momentum. William Blau himself also used triple smoothing, This indicator lets you choose between double and triple smoothing. If you set the third smoothing period to 1, you will get double smoothing, and the indicator will display identical results with the NinjaTrader default indicator.

Smoothing with different moving averages: William Blau has suggested to use the EMA for double or triple smoothing. This indicator offers you a selection of more than 30 different moving averages for the smoothing. The default is set to EMA in line with the original indicator.

Signal Line: I have added a signal line for timing entries and exits. The signal line is obtained by smoothing the TSI with one of the selectable moving averages, similar to the signal line of the MACD. The default period for the signal line is 7.

Histogram: The indicator has an option to plot a histogram, which shows the difference between TSI and signal line.

Trend definition: The indicator exposes the current trend via an IntSeries. The trend can be determined based on the TSI (rising & not oversold, falling & not overbought, neutral), the signal line (rising & not oversold, falling & not overbought, neutral)) or the TSI / signal line crosses. All trend definitions are not straightforward, but require a higher close to switch to an uptrend, or a lower close to switch to a downtrend. Moreover the DSM / signal line cross will only show an uptrend, when not oversold and a downtrend when not overbought.

Paint bars: The paintbars can be used to plot the trend information. The trend states are uptrend, downtrend and neutral trend as explained above. It is possible to apply the indicator to the price panel and unselect the indicator plots. This allows to use the indicator as a "paintbar only" indicator.

Sound alerts: The indicator comes with sound alerts which are triggered when the trend changes. The sound files are included with the zip file and should be manually copied into the directory Documents -> program files (x86) -> NinajTrader 7 -> sounds.

Update March 13, 2014: Trend filter, paint bars, sound alerts and histogram added.
Update November 16, 2015: Momentum period added. Option added to select from different moving averages.

Note: The parameter structure of the indicator was changed. In case that you have used the prior version of the anaTSI as input series for other indicators or strategies, these indicators or strategies will only work, if you change the syntax of the indicator call to conform with the new parameter structure.
