MTF Ploting

[dotnetfreak]

Hi all,

Im trying to develop a MTF indicator that plots data from higher timeframes.
I wanted to start simple to test MTF functionality but Im lost.

I already searched and read here and bigmike forums but cannot find the path.

I have the following code, but I cannot see any line ploted:

protected override void Initialize()
        {
            Add(new Plot(Color.FromKnownColor(KnownColor.AppWorkspace), PlotStyle.Line, "M15"));
            Add(new Plot(Color.FromKnownColor(KnownColor.Red), PlotStyle.Line, "H1"));
            Add(new Plot(Color.FromKnownColor(KnownColor.Yellow), PlotStyle.Line, "H4"));
            Add(new Plot(Color.FromKnownColor(KnownColor.Green), PlotStyle.Line, "D1"));
			
			Add(PeriodType.Minute, 60);
			Add(PeriodType.Minute, 240);
			Add(PeriodType.Day, 1);
            Overlay				= true;
        }

     
        protected override void OnBarUpdate()
        {
            
        M15.Set(SMA(BarsArray[0],20)[0]);
		H1.Set(SMA(BarsArray[1],20)[0]);
        H4.Set(SMA(BarsArray[2],20)[0]);
        D1.Set(SMA(BarsArray[3],20)[0]);
        }

Thanks in advance

P.D. I loaded 90 days of data, so the needed bars are there

Hello dotnetfreak,

Thank you for your post and welcome to the NinjaTrader Support Forum!

You will need to add a check for the bars needed, in this case 20 as the SMA is using a 20 period. The code at the beginning of your OnBarUpdate() needs to reflect the following:

if(CurrentBars[0] <= 20 || CurrentBars[1] <= 20 || CurrentBars[2] < = 20)
return;

For information on CurrentBars please visit the following link: http://www.ninjatrader.com/support/h...urrentbars.htm

And for information on ensuring you have enough data before accessing it please visit the following link: http://www.ninjatrader.com/support/f...ead.php?t=3170

Please let me know if you have any questions.
