TRIX Indicator for ESignal

[jbergeron]

Greetings,

Thought perhaps someone could use this; appologies if someone has already posted this:

This is a 6 period TRIX study.

var StudyEMA1 = new MAStudy(6, 0, "close", MAStudy.EXPONENTIAL);
var StudyEMA2 = new MAStudy(6, 0, StudyEMA1, MAStudy.MA, MAStudy.EXPONENTIAL);
var StudyEMA3 = new MAStudy(6, 0, StudyEMA2, MAStudy.MA, MAStudy.EXPONENTIAL);
var prev_ema3 = null;
var trix = null;

function preMain()
{
    setPriceStudy(true);
    setDefaultBarThickness(1, 0);
    setCursorLabelName("Trix 6", 0);
    setDefaultBarFgColor(Color.red, 0);
}

function main()
{       
    if (getBarState() == BARSTATE_NEWBAR)
    {
        ema1 = StudyEMA1.getValue(MAStudy.MA);
        ema2 = StudyEMA2.getValue(MAStudy.MA);
        ema3 = StudyEMA3.getValue(MAStudy.MA);
        
        if (prev_ema3 != null)
            trix = ema3 - prev_ema3 / prev_ema3;
        
        prev_ema3 = ema3;
        
    }
    
    if (trix != null)
        return trix;
    
} 

Cheers,
