Plotting High at begging of a chart

[GKonheiser]

Morning,

I am new trying to plot the high in a variable range of opening bars on a chart if Low[0] < Low[Range of Current bars]

So something like but with code that works : )

If (Low[0] < Low[ Range between Low[0] & beginning of chart ]

{
DrawDot( "FirstHigh", true, MAX(High, Range between Low[0] & begging of chart), High[MAX(High, Range between Low[0] & begging of chart)], Color.Black)

}



The Code is just to convey what im trying to do. I tried a few things but had various overload errors.

If some one could point me in the right direction I would be most grateful.

GKonheiser, unfortunately I guess I'm not exactly on what you're trying to achieve here. When would the plotting of the start High of the chart be triggered? When the current Low value is smaller than the mid of Low and the chart start low?

Hi Bertrand,

What I am looking to do is, when a chart starts and prices are increasing , remember the low, when prices fall back though the low draw a dot on the high in-between the two points.

IE chart open at 50 rally's up to 75 and the falls back through 50, a dot would appear at the high of 75 once we have broken through 50.


Does that make sense?

It is part of something bigger im building.

Yes, that makes sense - thanks. As a courtesy please find a small example attached that would implement this pretty straightforward by keeping track in variables of the values needed for reference. You see the condition to paint the high by the vertical line, currently the Close price is used but you may change of course.

This could be further extended to for example reset of each open / session break - however hope this simple example would get you going.

Hi Again,

thanks very much for that, ive written the following code and im getting an error and im not sure why:-

// This namespace holds all indicators and is required. Do not change it.
namespace NinjaTrader.Indicator
{
/// <summary>
/// Enter the description of your new custom indicator here
/// </summary>
[Description("Enter the description of your new custom indicator here")]
public class HiLo : Indicator
{

// Wizard generated variables
private double startLow;
private double firstHigh;
private int firstHighBar;
private bool startBool = true;
// User defined variables (add any user defined variables below)


/// <summary>
/// This method is used to configure the indicator and is called once before any bar data is loaded.
/// </summary>
protected override void Initialize()
{
Add(new Plot(Color.FromKnownColor(KnownColor.Orange), PlotStyle.Line, "Plot0"));
Overlay = false;
}

/// <summary>
/// Called on each bar update event (incoming tick)
/// </summary>
protected override void OnBarUpdate()
{
if(startBool)
{
if(CurrentBar == 0)
{
startLow = Low[0];
firstHigh = High[0];
}

if(High[0] > firstHigh)
{
firstHigh = High[0];
firstHighBar = CurrentBar;
}

if(Low[0] < startLow)
{
DrawDot("firstHigh", true, firstHighBar, High[firstHighBar],Color.Black);
startBool = false;
}

}


}


The error im getting is:-
NinjaScript File Error Code Line Column
Strategy\HighLow.cs Cannot implicitly convert type 'int' to 'bool' CS0029 - click for info 44 17
Strategy\HighLow.cs Cannot implicitly convert type 'int' to 'bool' CS0029 - click for info 50 17

[NinjaTrader_Bertrand]

You're welcome, is the compile error truly coming from this very script? The compiler finds an issue with HighLow, yet yours is called HiLo?

Just double click on the error generated and it will take directly to the offending script / code part.

[GKonheiser]

Of course, yup your correct. sorted now ; )
