Inputs[1]

[zeller4]

Hello,

I've modified the SMAFromRangeBars file to an EMAFromMinuteBars file. I'm attempting to use more than one plot so I've added a second BarsInProgress series.

Please tell me if I'm using "Inputs[1]" and "Inputs[2]" and "init" correctly.

protectedoverridevoid OnStartUp()
{
average = EMA(Inputs[1],period);//private EMA
smoothedAverage = EMA(rawAverage,Smooth);//private EMA (DataSeries,int)
average2 = EMA(Inputs[2],period2);//private EMA
smoothedAverage2 = EMA(rawAverage2,Smooth);//private EMA (DataSeries,int)
init = false;
} 

if(BarsInProgress == 0)//base chart
{
if (!init)//from OnStartUp
{
rawAverage.Set(Input[0]);
}
else
{
rawAverage.Set(avgValue);
}
if (!init2)//from OnStartUp
{
rawAverage2.Set(Input[0]);
}
else
{
rawAverage2.Set(avgValue2);
}
Value.Set(smoothedAverage[0]); 
EMA2_from_timeBars.Set(smoothedAverage2[0]); 
}
if (BarsInProgress == 1)
{
init = true;
avgValue = average[0];


}
if (BarsInProgress == 2)
{
init2 = true;
avgValue2 = average2[0];


}

Thanks,
Kirk

I also added this to the code in OnBarUpdate when I noticed it didn't plot at the higher timeframe:

if (CurrentBar < 21)
return;

Hi Kirk,

Inputs is not supported NinjaScript. Indicators have only one input series selection. Using Inputs won't provide any convenience for changing the input series of a secondary series. It will compile and produce a value, but the best practice is using Closes[1], Closes[2] in its place.

Hello Ryan and others,

Can you please tell me how to plot this on tick charts? I've tested a couple things but no success yet.

Thanks,
Kirk

Hi Kirk,

For multiseries indicators, it's important to exclude processing until there are objects available. The following statement should help for this:

if (CurrentBar < 0 || CurrentBars[1] < 0) return;

If you are still running into issues, check the log tab of the control center for any error messages.

Hi Ryan,

you said:

if (CurrentBar < 0 || CurrentBars[1] < 0) return;

not sure if you meant

 if (CurrentBar < Period || CurrentBars[1] < Period) return;

?

No, not necessarily. Checking for all CurrentBars[x] < 0 may be the minimum you want to do, but the actual values used will depend how your script is coded - If you reference prior bar values, exact calculations, etc.

These lines are designed to prevent NT from accessing objects that don't exist. To find exactly what's right for your script, try - catch blocks should be used to debug and find when it runs into this type of exception.
