Hi Bruce,

I have found discussions on TSI but not sure it is what I'm looking for.  I use the following which I have translated from Amibroker to Metastock.  IS it possible to do the same for TC2000 v12.3:

Ratio:= (CLOSE - Ref(CLOSE,-10)) / ATR(10)  ;

The Trend Strength Indicator you describe is not the same as the True Strength Indicator in TC2000.

If the ATR is simple, then you could create an Indicator Formula for the Ratio as:

(C - C10) / ((AVGH10 - AVGL10) / 2 + (ABS(H - C1) + ABS(C1 - L) + ABS(H1 - C2) + ABS(C2 - L1) + ABS(H2 - C3) + ABS(C3 - L2) + ABS(H3 - C4) + ABS(C4 - L3) + ABS(H4 - C5) + ABS(C5 - L4) + ABS(H5 - C6) + ABS(C6 - L5) + ABS(H6 - C7) + ABS(C7 - L6) + ABS(H7 - C8) + ABS(C8 - L7) + ABS(H8 - C9) + ABS(C9 - L8) + ABS(H9 - C10) + ABS(C10 - L9)) / 20)

If you use this as a Custom PCF Indicator, you could then add the 10-Period and 100-Period Simple Moving Averages to this calculation.

You can include one of the moving averages in the Custom PCF Indicator if desired by setting the Period of the Custom PCF Indicator to either 10 or 100 (if you want the indicator to just be a single line representing Mov(Mov(Ratio,10,S),100,S), then you would probably want to use 100). You can set the Opacity of the Custom PCF Indicator all the way to left to make it so the Custom PCF Indicator is not visible if desired.

Adding and Moving Indicators

Thanks.  True Strength is very very similar (raw) to TSI.   

You're welcome.
