Add instrument to chart in STRATEGY Analyzer

[alexstox]

Thank you very much, Patrick!!!!!!! How couldn't I see this?! Too lot period near PC =)

Should this construction be always here?

get 
			{
				if ((myIndex1 == "") && (ChartControl != null) && (Instruments != null)) 
					for(int i=0; i<ChartControl.BarsArray.Length; i++)
						if (ChartControl.BarsArray[i].Instrument.FullName != Instruments[0].FullName)
						{
							 myIndex1 = ChartControl.BarsArray[i].Instrument.FullName;
							break;
						}
				return myIndex1; 
			}
            set { myIndex1 = value.ToUpper(); }

If I will use DrawLine() instead of Plot() in indicator script, can I draw MyIndex1 to left scale and MyIndex2 to right scale and how to do this?

Hello alexstox,

Thank you for your response.

The check for the instrument name is not necessary unless it is needed that the instrument not be the same as the main data series.

For the DrawLine() can you explain which is considered the right and left scale on the chart? Can you provide a screenshot of manually drawn lines for these?

I look forward to your response.

1) MyIndex1 will be via Plot() on the righ scale and MyIndex2 via DrawLine() on the left scale.

}

After I inserted this indicator to the chart, MyIndex3 is the same as main instrument. Is it because of "Instruments[0].FullName" or "myIndex3=value"? Last I changed because use name of own instruments with upper and lower case. Maybe I did some mistake.

Hello alexstox,

Thank you for your response.

You can use ScaleJustification, however it can only be set to one setting per indicator. So you would need two indicators; one for the plot and one for the DrawLine(): http://www.ninjatrader.com/support/h...tification.htm

For your second item did you change the string to the desired instrument or leave it blank? If it was blank it will just plot the close of the main series.

[alexstox]

1) You can use ScaleJustification...

2) For your second item did you change the string to the desired instrument or leave it blank? If it was blank it will just plot the close of the main series.

1) Well, ScaleJustification is useful only in strategy where I can set it for every indicator.

2) Can you show me what condition in script command to do this, if I leave it blank?

3) what is

Instruments[0]

I didn't find any info in HelpGuide

[NinjaTrader_PatrickH]

Hello alexstox,

Thank you for your response.

Can you show me what condition in script command to do this, if I leave it blank?

What item are you referring to as blank?

For your third item, Instruments[0] would be the main instrument the indicator or strategy was applied to.

[alexstox]

Patrick, you wrote
"For your second item did you change the string to the desired instrument or leave it blank? If it was blank it will just plot the close of the main series."

Can you please show me what condition command to "plot the close of the main series"?

[NinjaTrader_CalH]

Alexstox,

If you do not define an instrument for the Add() method it will default to create a data series of the main instrument.

Not defining it is leaving the test field blank for Myindex3.

[alexstox]

Hello dear support team. Why after I set ScaleJustification to left and right for 2 indicators in one panel, they still both on right scale? I added those indicators to strategy script.

Add(MyIndex(MyIndex1));
MyIndex(MyIndex1).Panel=2;
MyIndex(MyIndex1).ScaleJustification=ScaleJustification.Left;
			
Add(MyIndex(MyIndex2));
MyIndex(MyIndex2).Panel=2;
MyIndex(MyIndex1).ScaleJustification=ScaleJustification.Right;

[NinjaTrader_CalH]

Aelxstox,

it is because you are changing the same MyIndex scale justification from left to right. Change the second MyIndex to MyIndex(MyIndex2)

MyIndex(MyIndex1).ScaleJustification=ScaleJustific ation.Left;

MyIndex(MyIndex1).ScaleJustification=ScaleJustific ation.Right;

[alexstox]

I saw mistake after reading own question =) Thanks

[alexstox]

Please give me sample where I can manage color and line style of indicator from strategy script.

[NinjaTrader_CalH]

Color -
Plots[0].Pen.Color = Color.Blue;

Plotstyle -
Plots[0].PlotStyle = PlotStyle.Line;

Plots HelpGuide link -
http://www.ninjatrader.com/support/h...html?plots.htm

[alexstox]

Color -
Plots[0].Pen.Color = Color.Blue;

Plotstyle -
Plots[0].PlotStyle = PlotStyle.Line;

Plots HelpGuide link -
http://www.ninjatrader.com/support/h...html?plots.htm

What mean [0] in Plots[0]? Is it refer to first indicator that added in strategy? And if there are 3 indicators, will be Plots[0], Plots[1], Plots[2]?

And what if I need to change Bollinger? (Lower, Upper, MA)?

[NinjaTrader_CalH]

Correct.

However, note that the plots is going to be per indicator that is added to the strategy.

So if I added the MACD and SMA to my Strategy.

Add(MACD(6,12,9));
Add(SMA(14));

SMA(14).Plots[0].Pen.Color = Color.Blue;
MACD(6,12,19).Plots[0].Pen.Color = Color.Yellow;

Each Plots is going to be the indexed plots for that indicator.
Since the SMA has only one plot then it would be Plots[0]
The MACD has 3 plots so Plots [0,1,2]
