For Live Market data, how do I display on Market Analyzer Column last closed price bar for 3min interval? and another column for previously closed price bar for 3min interval?

Hello AlwaysOnTop629,

Set IsDataSeriesRequired to true in State.SetDefaults.

https://ninjatrader.com/support/helpGuides/nt8/isdataseriesrequired.htm

When adding the column, set the Data Series Type to Minute, and the Value to 3.

Assign CurrentValue the value of Close[0].

Or check CurrentBar is greater than 1 and assign CurrentValue the value of Close[1] (of 1 bar ago).

I'm new to scripting. please help.
Using NinjaScript Editor, do I create a "New indicator" or "New Market Analyzer Column"?

//This namespace holds MarketAnalyzerColumns in this folder and is required. Do not change it.
namespace NinjaTrader.NinjaScript.MarketAnalyzerColumns
{
public class PriceClosedAMarketAnalyzerColumn : MarketAnalyzerColumn
{
protected override void OnStateChange()
{
if (State == State.SetDefaults)
{
Description = @"Enter the description for your new custom Market Analyzer Column here.";
Name = "PriceClosedAMarketAnalyzerColumn";
Calculate = Calculate.OnBarClose;
IsDataSeriesRequired = true;
}
else if (State == State.Configure)
{
protected override void OnMarketData(Data.MarketDataEventArgs marketDataUpdate)

{

CurrentValue = Close[0] ;

}
}
}
}
}

Hello AlwaysOnTop629,

You can add an indicator that has a plot to the Market Analyzer by adding an Indicator column.

Or you create the script as a MarketAnalyzerColumn.

In your first post you suggested you are trying to make a MarketAnalyzerColumn.

However, if you made an indicator that could be used in the Market Analyzer, on Charts, and can be called from NinjaScript Strategies.

So it depends, what you do want out of the script?

Hello,
I want an indicator to show the closed price of a 3 minutes bar of 1 bar ago and 2 bars ago and
display that value on Market Analyzer Column A & Column B.
Column A display "1 bar ago Close Price Value"
Column B display "2 bar ago Close price Value"

Thank you,

Hello AlwaysOnTop629,

You can do that in an indicator. You can do that in a Market Analyzer Column.

Either will work.

Hello,
I created the indicator script and I'm able to display the last close price on a market Analyzer Column.
Is my code efficiently and not use too much resources?
Can you help me improve it to be better?

Thank you,

namespace NinjaTrader.NinjaScript.Indicators
{
public class PriceCloseLastPrice : Indicator
{
protected override void OnStateChange()
{
if (State == State.SetDefaults)
{
Description = @"Price Close last bar Price --Close [0]";
Name = "PriceCloseLastPrice";
Calculate = Calculate.OnBarClose;
IsOverlay = false;
DisplayInDataBox = true;
DrawOnPricePanel = true;
DrawHorizontalGridLines = true;
DrawVerticalGridLines = true;
PaintPriceMarkers = true;
ScaleJustification = NinjaTrader.Gui.Chart.ScaleJustification.Right;
//Disable this property if your indicator requires custom values that cumulate with each new market data event.
//See Help Guide for additional information.
IsSuspendedWhileInactive = true;
AddPlot(Brushes.Red, "ClosePlot");
}
else if (State == State.Configure)
{
}
}

protected override void OnBarUpdate()
{
Value[0] = Close[0]; //this will draw a line on the close price.
}
}
}

Hello AlwaysOnTop629,

Add a public Series<double> using XmlIgnore so this can be used in the Market Analyzer and Strategy Builder.

See the forum post linked in post # 4.

There is not anything can be be improved performance wise. The script only assigns the Close[0] price to the plot and is set to use Calculate.OnBarClose. That's as simple as it can get.
