Need help - TSI - Function in ACSIL

September 11th, 2012, 09:07 PM

Hello - Can any one help with converting this function to ACSIL? There is built in True strength indicator(scsf_TrueStrengthIndex) available in Sierra but - I would like to have it in more generic form - where it can be called multiple times with various parameters.

Thanks in advance.

Here is the TS Code:

TSI Function:
----------------

Code

{TSI function = True Strength Index by Bill Blau}

{FORMAT: TSI(Price,r,s,u)
Where: r = length of first EMA smoothing of 1 day momentum,
s = length of second EMA smoothing of 1 day smooting,
u = length of third EMA smooting of 1 daymomentum.}

Inputs:
Price(NumericSeries), r(NumericSimple), s(NumericSimple), u(NumericSimple);

Value1= 100*TXAverage(Price-Price[1],r,s,u) ; { Numerator }
Value2=TXAverage(AbsValue(Price-Price[1]),r,s,u) ; { Denominator }

If Value2 <> 0 then TSI = Value1 / Value2 else TSI = 0;

TXAverage Function:
--------------------------

Code

{TXAverage function

FORMAT: TXAverage(Price,r,s,u) }

Inputs: Price(NumericSeries), r(NumericSimple),s(NumericSimple),
u(NumericSimple);

TXAverage = XAverage(XAverage(XAverage(Price,r),s),u) ;

Indicator code (to demonstrate the repeat use of the function - Which I am unable to replicate in Sierra):
-------------------

Code

plot1(xaverage(TSI(High,10,20,30),5));
plot2(xaverage(TSI(Low,10,20,30),5));
