Program EMA price line pivot gaps

[amcdonald]

As a novice, I'm baffled by a programming issue. My intent seems simple enough. I want to chart in a panel a line EMA of the price. I would further like to color the EMA line green when it is rising and red when it is falling. In the OnBarUpdate() section I use the following coding.

if (CurrentBar < Period) return;

if (EMA(Period) [0] >= EMA(Period) [1])
{
Upline.Set(EMA(Period) [0]);
}
else
{
Dnline.Set(EMA(Period) [0]);
}

It compiles fine, but when I run it, every period following a pivot point, up or down, is blank. Everything else between pivots displays as expected. I would greatly appreciate any assistance in moving beyond my first NinjaTrader program.

Hello,

The EMA should only have one Plot set if you want it to be a continuous line.

You can also use the Rising() and Falling() methods to help determine when the line is rising or falling.

If you have not yet, I would suggest reviewing our Indicator Reference Sample on Multi-Colored Plots for more information:
