Another TRIX formula from Tradestation. made by some programmer. has TRIX and a signal line with it.

inputs:
TRIXLength( 5 ),
SigLineXMALen( 3 ) ;

variables:
EMA1( 0 ),
EMA2( 0 ),
EMA3( 0 ),
TRIXLine( 0 ),
SignalLine( 0 ) ;
EMA1 = XAverage( Close, TRIXLength ) ;
EMA2 = XAverage( EMA1, TRIXLength ) ;
EMA3 = XAverage( EMA2, TRIXLength ) ;
if EMA3[1] <> 0 then
{ Ensure not about to divide by zero }
TRIXLine = 10 * ( EMA3 - EMA3[1] ) / EMA3[1] ;
SignalLine = XAverage( TRIXLine, SigLineXMALen ) ;
Plot1( TRIXLine, "TRIXLine" ) ;
Plot2( SignalLine, "SignalLine" )
