I have entered the following code from the book "Momentum, Direction &
Divergences"
by Bill Blau:

{ User Function:  TSI_Trade = True Strength Index Trade by Bill Blau}

{Triple exponential moving averages are used.}

{FORMAT:  TSI_TRADE(PRICE,r,s,u) }

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

Value1 = TSI(Price,r,s,u);

If Value1 - Value1[1] > 0 AND Value1 > 0 then
        Value2 = value1
Else
        Value2 = 0;

If value1 - Value1[1] < 0 AND Value1 < 0 then
        Value3 = Value1
Else
        Value3 = 0;;

TSI_Trade = Value2 + Value3;


My question is:  How do I display TSI_Trade as and indicator?

Thanks,
Randy
