Change an Indicator Color in a Strategy

[NinexTim]

I created a MA crossover strategy using the Strategy Wizard. I selected true for plot on chart. The MAs show up on the chart, but they are both the same color. How can I change the colors of the indicators?
This is what the source code looks like:
protected override void Initialize()
{
Add(EMA(14));
Add(EMA(28));
}

Thanks, Tim

NinexTim,

Here is a relevant link : http://www.ninjatrader.com/support/f...ead.php?t=3227

Please let me know if I may assist further.

Adam,
From the looks of the link you sent me, I can't change the color using the Add statement that I have. I unlocked the code and copied the Add(new Plot ... that was in the example. Now I get multiple errors when I compile.
This is the code I added:
protected override void Initialize()
{
//Add(EMA(14));
//Add(EMA(28));
Add(new Plot(Color.FromKnownColor(KnownColor.DarkRed), PlotStyle.Line, "Upper"));
Add(new Plot(Color.FromKnownColor(KnownColor.Black), PlotStyle.Line, "Lower"));
}

protected override void OnBarUpdate()
{
Lower.Set(EMA(14)[0]);
Upper.Set(EMA(28)[0]);
}

These are the errors:
The best overloaded method match for 'NinjaTrader.Strategy.StrategyBase.Add(NinjaTrader .Indicator.IndicatorBase)' has some invalid arguments
Argument '1': cannot convert from 'NinjaTrader.Gui.Chart.Plot' to 'NinjaTrader.Indicator.IndicatorBase'
The name 'Lower' does not exist in the current context
The name 'Upper' does not exist in the current context

Thanks, Tim

NinexTim,

What error messages are you getting?

You can also do something like PlotColors[0][0] = Color.Red; in OnBarUpdate

Adam,
Here are the errors I'm getting. Do I need to declare Upper and Lower somewhere?
Thanks, Tim

Tim,

Please try this formatting :

Add(new Plot(new Pen(Color.Black, 2), PlotStyle.Line, "CCI_Plot"));

Please let me know if I may assist further.

[NinexTim]

Adam,
I put the line you suggested in the Initialize portion of my code:
protected override void Initialize()
{
Add(new Plot(new Pen(Color.Black, 2), PlotStyle.Line, "CCI_Plot"));

I still get the same errors as before:
The best overloaded method match for 'NinjaTrader.Strategy.StrategyBase.Add(NinjaTrader .Indicator.IndicatorBase)' has some invalid arguments
Argument '1': cannot convert from 'NinjaTrader.Gui.Chart.Plot' to 'NinjaTrader.Indicator.IndicatorBase'

Thanks, Tim

NinexTim,

Apologies, I overlooked that you are working with a strategy here. That is indicator code only.

One thing to remember here is you can't add plots like this to a strategy. I would suggest creating an indicator first, then you can add the indicator to your strategy.

Change an Indicator color in a Strategy (SOLUTION)

Tim,

I know this is a bit late, but hopefully it will help some people who are trying to do the same.

To change the color of an Indicator in a Strategy, you have to get the Pen object of the Indicator's Plot and change the color of the Pen object.

Here's an example:

        protected override void Initialize()
        {
            Add(EMA(10));
            CalculateOnBarClose = true;
        }

        protected override void OnBarUpdate()
        {    
            Pen my_pen = this.Indicators[0].Plots[0].Pen;
            my_pen.Color = Color.Red;
        } 

You can do this for each of your Indies by changing the '[0]' after 'Indicators' to 1, 2, 3, etc...

I haven't tried this with a different style of indicator, however I imagine it would work similarly.

Kenny, thanks for your update on this topic.
Unless you want to change the plot colors dynamically in your strategy, I would prefer setting the indicator plots colors in the Initialize() section.
Also added an example how to set the plot line thickness and DashStyle.

[FONT=Courier New][COLOR=#007700]protected [/COLOR][COLOR=#0000bb]override void Initialize[/COLOR][/FONT][FONT=Courier New][COLOR=#007700]() [/COLOR][/FONT]
[FONT=Courier New][COLOR=#007700]{ [/COLOR][/FONT]
[FONT=Courier New][COLOR=#0000bb]Add(EMA(10));[/COLOR][/FONT]
[FONT=Courier New][COLOR=#0000bb]EMA(10).[COLOR=blue]Plots[0].Pen.Color = Color[/COLOR].Red;  [/COLOR][COLOR=seagreen]// set plot color[/COLOR][/FONT]
[FONT=Courier New][FONT=Courier New][COLOR=#0000bb]EMA(10).Plots[0].Pen[/COLOR][COLOR=blue].Width[/COLOR][/FONT][/FONT][COLOR=sandybrown][COLOR=blue][FONT=Courier New][FONT=Courier New] = 2[/FONT][/FONT][FONT=Courier New][FONT=Courier New];          [COLOR=seagreen]// set line width[/COLOR][/FONT][/FONT][/COLOR][/COLOR]
[COLOR=sandybrown][FONT=Courier New][FONT=Courier New][COLOR=#0000bb]EMA(10).[/COLOR][/FONT][/FONT][COLOR=blue][FONT=Courier New][FONT=Courier New]Plots[[/FONT][/FONT][FONT=Courier New][FONT=Courier New][FONT=Courier New]0[/FONT][/FONT][/FONT][FONT=Courier New][FONT=Courier New]].Pen.DashStyle = DashStyle.Dash; [COLOR=seagreen]// set DashStyle [/COLOR][/FONT][/FONT][/COLOR][/COLOR]
 }

how to do this with BB

Marcow thank you

How to do this for the Bowlinger band
I am trying to make the middle line disappear but code gives error:

Bollinger(2,Bb).Middle.Plots[0].Pen.Color = Color.Transparent;

any suggestions?

[NinjaTrader_Bertrand]

yeshe, the plots would go strictly by collection index and not be name here, so I would suggest to instead try with (second plot at index 1 is the middle plot).

Bollinger(2,Bb).Plots[1].Pen.Color = Color.Transparent;

[yeshe]

Bertrand
works
great!

[RicRules]

does anyone have ideas on how i can change the colors of NinjaTrader RMI main line to Red (for example) when great than 50 and Green when less than 50

[NinjaTrader_MichaelM]

Hello RicRules,

Thank you for writing in. There are not any built in NinjaTrader indicators called RMI. Did you possibly misspell the acronym or are you referring to an indicator you downloaded on the internet? If you can please attach the indicator you are referring to to your response, I can assist further.

Thank you in advance.
