Change Indicator Plot Color in a Strategy

[alexstox]

For that I would look into changing the PlotColors of your placeholder indicator instead of the Pen Color -

StrategyPlot(0).PlotColors[0][0]

what is StrategyPlot(0)? I tried PlotColors[0][0] in strategy, but it only for indicators.

Alexstox,

Bertrand was using StrategyPlot(0) as an example for the indicator name.

You would need to call the indicator such as SMA and then use the PlotColors

SMA(14).PlotColors[0][0] = Color.Red;

I tried to do like that, but get this message
Error on calling 'OnBarUpdate' method for strategy 'MyStrat/9cfac36bb3a0413a8fd7ab22487c0d3c': Index was outside the bounds of the array.

Even when I add this before change plot
if(CurrentBars[1]>300) ....

Alexstox,

With the CurrentBars[1] I assume you are adding an additional data series to your script correct?

You are right.

 protected override void Initialize()
        {
             Add(MyInstrum1,PeriodType.Day,1);
             Add(MyInstrum2,PeriodType.Day,1);

Add(SMA(Closes[2],50));
SMA(Closes[2],50).Panel=3;
SMA(Closes[2],50).ScaleJustification=ScaleJustification.Right;

Add(SMA(Closes[1],50));
SMA(Closes[1],50).Plots[0].Pen.Color=Color.Red;
SMA(Closes[1],50).Panel=3;
SMA(Closes[1],50).ScaleJustification=ScaleJustification.Right;

............................................
 protected override void OnBarUpdate()
        {
// Checks to ensure all Bars objects contain enough bars before beginning
if (CurrentBars[0] <= ATR_big_per || CurrentBars[1] <= BarsRequired || CurrentBars[2] <= BarsRequired)
	return;
......................................
SMA1=SMA(Closes[1],50); SMA2=SMA(Closes[2],50);
if (SMA2>0 && SMA2>SMA1) 
{
     if(CurrentBars[2]>300) SMA2.PlotColors[2][0]=Color.Green;
}
else if (SMA1>0 && SMA1>SMA2) 
{
    if(CurrentBars[1]>300) SMA1.PlotColors[1][0]=Color.Green;
}
else return;

alexstox, looks to me like you try to access a non present plot index for your PlotColors call, the SMA's would actually only hold one plot per instance, right? So that plot to change would always be at index 0.

Changed to .PlotColors[0][0]=Color.Green;
Color of indicator didn't change

Alexstox,

Can you please repost your adjusted script so I can see what you have changed?

Alexstox,

There are couple things here that need clarification.

First, in the Initialize() you are adding SMA's that are accessing other BarArrays. However, this will not work as you expect, this is because you can't access other added data series in the Initialize() as these have not been cached and built yet, and will default to the primary data series.

Second, Is the SMA1 and SMA2 a SMA variable or double variable?
Your calculations are trying compare a Indicator, SMA, to a double value which you cannot do.

I agree with First, I just carry plotting from strategy to indicator

About Second. SMA1 and SMA2 are double variables. What variable should I use instead of long code of indicator? I mean how to declare "indicator" variable? To get short SMA1 instead of long code SMA(bla,bla,bla). This is especially useful in own indicators with lots of inputs.
