Add additional Periods and Plots to TRIX?

[JSBatch]

Newbie question here....

I want to add additional Periods and Plots to the TRIX indicator as included in the NT 6.5. System Indicators. I figured out how to add the add the additional Plots to the 'stock' indicator code but I can't absolutely determine what portion of the code calculates the Periods and Input. I believe this is the portion of the code that calculates the Periods:

if (CurrentBar == 0)
{
Value.Set(Input[0]);
return;
}

EMA tripleEma = EMA(EMA(EMA(Input, period), period), period);
double trix = 100 * ((tripleEma[0] - tripleEma[1]) / tripleEma[0]);

Default.Set(trix);
Signal.Set(EMA(Default, signalPeriod)[0]);
}

Can anyone offer any guidance on how I would modify this code to indicate FOUR TRIX Periods and FOUR TRIX Plots?

Many thanks!!

JSB, welcome to our forums here - are you looking simply looking for 4 times smoothed TRIX?

protected override void OnBarUpdate()
{
if (CurrentBar == 0)
{
Value.Set(Input[0]);
return;
}

EMA quadEma = EMA(EMA(EMA(EMA(Input, period), period), period), period);
double trix = 100 * ((quadEma[0] - quadEma[1]) / quadEma[0]);

Default.Set(trix);
Signal.Set(EMA(Default, signalPeriod)[0]);
}

Yes, I believe this is what I desire. I will try the code snippet and advise as to my success. Many thanks for your quick reply and your help!

Hi Bertrand -

The code snippet that you provided did not accomplish what I am try to accomplish with the TRIX indicator.

What I want to do is plot 4 EMA Periods and a Signal on one TRIX indicator - and have input access to the Periods and Signal in the Parameter section of the indicator configuration window. The image below will give you an idea what I am driving toward.

Thanks!

The easiest to setup the chart you have is just load the TRIX then 4 times to it with your custom period settings, as you load the indicator to the chart just select to plot them all in the same Panel.

Thanks. Did as you suggested and works fine. How can I prevent the parameter settings from displaying in the indicator label?

You would need to setup the indicators then with a blanked outn label field in the indicator properties, then the paramters and indicator names are not displayed at all.

I do want to display at one label (TRIX) on the indicator panel but want to exclude the parameter settings from this label display.

You would need to address this then in your code via the steps shown in the sample - http://www.ninjatrader.com/support/f...ead.php?t=4749

Thanks. Will modify Label code as suggested in the sample.
