be able to change color in exported strategy with indicator

[tkaboris]

HI,
I have strategy that calls on external indicator, when I export strategy it includes an indicator. Indicator itself has settings to change colors, however when I export the strategy and load it, down there under indicators there is no way to change colors.


Is there a way export and be able change colors of an indicator in strategy basically?

Hello tkaboris,

The settings would have to be set by the strategy.

private MyIndicator indy;

indy = MyIndicator();
indy.MyProperty = 5;

You could add public properties to the strategy and use these to set the indicator values.

HI Chelsea B.

Still a bit confused. I have in my indicator

[NinjaScriptProperty]
[XmlIgnore]
[Display(Name="DownTrendColor", Description="Color of the down trend line.", Order=6, GroupName="Parameters")]
public Brush DownTrendColor
{ get; set; }

[Browsable(false)]
public string DownTrendColorSerializable
{
get { return Serialize.BrushToString(DownTrendColor); }
set { DownTrendColor = Serialize.StringToBrush(value); }
}

[NinjaScriptProperty]
[XmlIgnore]
[Display(Name="UpTrendColor", Description="Color of the up trend line.", Order=7, GroupName="Parameters")]
public Brush UpTrendColor
{ get; set; }

[Browsable(false)]
public string UpTrendColorSerializable
{
get { return Serialize.BrushToString(UpTrendColor); }
set { UpTrendColor = Serialize.StringToBrush(value); }
}

and in strategy i have
private BBTrendLine BTL;
BTL = BBTrendLine(false, Strength, true, false, 60, Brushes.Black, Brushes.Green, Brushes.Black, Brushes.Green,3);

I need to set Brushes.Black to DownTrendColor and Brushes.Green to UpTrendColor

Thank you

Hello tkaboris,

What is the method signature of this indicator call?
(So I know what each of the parameters in the indicator method call are)
You can take a screenshot of this from the intelliprompt.

[tkaboris]

its right here

Hello tkaboris,

From the signature it looks like you are supplying Brushes.Black as the downTrendColor and Brushes.Green as the upTrendColor.

When running the strategy is the strategy adding the indicator to the chart with AddChartIndicator() in State.DataLoaded?

Is the indicator not using the colors supplied by the strategy? (This might indicate a mistake in the code of the indicator)

[tkaboris]

Well signature uses downtrendcolor but its parameters are hard coded to black and gree.

When running the strategy is the strategy adding the indicator to the chart with AddChartIndicator() in State.DataLoaded?
Yes - AddChartIndicator(BTL);

Is the indicator not using the colors supplied by the strategy? (This might indicate a mistake in the code of the indicator)
no setting colors in indicator properties

[tkaboris]

if I load indicator seperatly all is showing fine

Hello tkaboris,

An indicator added by a strategy cannot be configured manually.

Is the indicator using the brushes supplied by the strategy?

[tkaboris]

Is the indicator using the brushes supplied by the strategy?
No, its not.

Hello tkaboris,

This may mean there is a mistake in the indicator.

Where is DownTrendColor used in the indicator code?

[tkaboris]

HI here are where its used in indicator
DownTrendColor = Brushes.Black;

if (ShowHistory)
{
Draw.ArrowDown(this, "UpTrendBreak" + unique + lineCount.ToString(), true, barsAgo, High[barsAgo] + TickSize, DownTrendColor);
}

[NinjaScriptProperty]
[XmlIgnore]
[Display(Name="DownTrendColor", Description="Color of the down trend line.", Order=6, GroupName="Parameters")]
public Brush DownTrendColor
{ get; set; }

[Browsable(false)]
public string DownTrendColorSerializable
{
get { return Serialize.BrushToString(DownTrendColor); }
set { DownTrendColor = Serialize.StringToBrush(value); }
}

Hello tkaboris,

It looks like the indicator is overriding whatever the user has set and is assigning DownTrendColor to Brushes.Black which would mean the user selecting the color when manually adding the indicator or when the strategy is adding the indicator will have no effect.

If that line is removed, does the behavior still occur?

[tkaboris]

If i comment out DownTrendColor = Brushes.Black; in indicator, standalone indicaotor still works as expected and i I change color it changes it.
indicator from strategy still has no parameters to change color.

[NinjaTrader_ChelseaB]

Hello tkaboris,

When you say "strategy still has no parameters to change color" I'm not sure I understand.

From your post # 5 it would look like this indicator as 4 parameters for colors in the overload parameters.

BTRendLine(bool alertOnBreak, int strength, bool showHistory, bool limitHistory, int limitHistoricalLookback, Brush downTrendColor, Brush upTrendColor, Brush downHistColor, Brush upHistColor, lineWidth)
