Hi Todd,

Someone made this a while back, I forget who.

Copy into indicators directory and compile.

Works in both 6.5 and 7.0 .

You can select EMA, WMA, SMA, and HMA.

Enjoy,

No, but it's easy. Here's one with some boilerplate elided:
(as shown requires https://nexusfi.com/free_downloads/ninjatrader-7/indicators/517-download.html?view)

 

Code

namespace NinjaTrader.Indicator { [Description("EMA colored green when rising and red when falling.")] public class jhlEMAColored : Indicator { #region Variables // Wizard generated variables private int period = 14; // Default setting for Period // User defined variables (add any user defined variables below) private JHL.Utility.EMA ema; private double prior; private int priorBar = -1; #endregion protected override void Initialize() { ema = new JHL.Utility.EMA(Period); Add(new Plot(Color.FromKnownColor(KnownColor.Green), PlotStyle.Hash, "Rising")); Add(new Plot(Color.FromKnownColor(KnownColor.Red), PlotStyle.Hash, "Falling")); Overlay = true; } protected override void OnBarUpdate() { if ( CurrentBar == 0 ) { prior = Input[0]; return; } double a = ema.set(Input[0], CurrentBar); if ( a > prior ) { Rising.Set(a); if ( Plots[0].PlotStyle == PlotStyle.Line && !Rising.ContainsValue(1) ) Rising.Set(1, Falling[1]); } else if ( a < prior ) { Falling.Set(a); if ( Plots[1].PlotStyle == PlotStyle.Line && !Falling.ContainsValue(1) ) Falling.Set(1, Rising[1]); } else { // Equality, set both and let NT deal with it? Rising.Set(a); Falling.Set(a); } if ( CurrentBar > priorBar ) { prior = a; priorBar = CurrentBar; } } #region Properties [Browsable(false)] // this line prevents the data series from being displayed in the indicator properties dialog, do not remove [XmlIgnore()] // this line ensures that the indicator can be saved/recovered as part of a chart template, do not remove public DataSeries Rising { get { return Values[0]; } } [Browsable(false)] // this line prevents the data series from being displayed in the indicator properties dialog, do not remove [XmlIgnore()] // this line ensures that the indicator can be saved/recovered as part of a chart template, do not remove public DataSeries Falling { get { return Values[1]; } } [Description("Number of periods in calculations.")] [GridCategory("Parameters")] publicint Period { get { return period; } set { period = Math.Max(1, value); } } #endregion } }

In NT7 we have the new PlotColors Method that allows the color of a single plot to be changed on the fly, without having to use the NT6.5 kluge of switching between different plots and repainting the segment connecting the current value to the value from one bar back.

So if we are plotting an MA to the first plot of an indicator, just do this to have different colors when the indicator is rising or falling.

If(Rising(Values[0]) PlotColors[0][0]=upColor;
if(Falling(Values[0])PlotColors[0][0]=downColor;

or do this to change the color based on the current value vs some threshold

if(Values[0]>SomeThresholdValue) PlotColors[0][0]=upColor;
if(Values[0]<SomeThresholdValue) PlotColors[0][0]=downColor;

The upColor and downColor can be user selectable. They need to be declared as variables, there must be Get/Set statements for them, and they need to be serialized.

There is a thread in the Ninjatrader forums called Multi Color Plot Approach that explains this further. This goes back to the early beta releases of NT7.

That really is better, it does the right thing on non-line plots, and on line plots it splits the difference.

Here is an example of a moving average that uses the PlotColors method to give user selectable colors for the rising and falling plot.

It's a triple smoothed EMA, not a simple EMA. It uses predefined instances of the EMA for optimization. Once more, thanks to Richard Todd of MoveTheMarkets.com for his article on this subject.

You may be surprised at how fast this indicator loads and refreshes. Further optimization can be accomplished by making an external call to a more efficient implementation of the EMA, rather than to @EMA.cs.

Every time I try down loading something I get error messages. I have tried more than one indicator, so I know something is wrong on my end. But I have no idea what. I have NT7, every time I try to compile it I get these stupid little error messages. Something about the name and blah blah blah

hey skyfly,

please stay in ONE thread with your comiling / importing-issues !
you have one main problem in your Ninja that causes all these errors when compiling / importing.

this has to be find & solved before anything else is working.
please stay here

When I try to input a zip file I get this import error .... hi skyfly, have a look here + try all those steps : maybe it brings you to a result and please report here if this helped you ! thanks! :crazy_pilot:

+ do all the steps, post screenshots of the errors etc to find out whats the problem at your side.
posting in diff threads makes no sense.
we will assist you if we can !

thanks max

Right ok...my bad, was just venting a little lol. Just because I have no idea how to fix this, or really even explain it. But I'll keep it in one area from now on. Sorry about that.
