Green Day Update

[wealthcig]

Hello Community,

I am trying to add a piece of the code to only look for a long arrows or a short arrow. Right now it looks in both directions. When I am looking for longs I would like to "click" a condition box to only show up arrows and the opposite for short.

Also is there a way to change the name of the indy? I did it inside of the code but when it was developed it is still saying GreenDay. I would like the new name to say Perfect Rotation Candle

Hello wealthcig,

Use a public bool with the [NinjaScriptProperty] attribute to make an input for the user to select.
[NinjaScriptProperty]
public bool ShowLongs
{ get; set; }

In the conditions that draw the arrow up, add a condition that bool is true.
if (ShowLongs /* && other conditions here */)
{
//Draw.ArrowUp() call here;
}


I would recommend making a copy of a script in the NinjaScript Editor, and using a new unique name.
Open the script in the NinjaScript Editor -> Right-click within the code area -> Save as

Then if you wish, re-export it using that new name.

I tried to input but had trouble. I am not sure where I should put it in the code. I put it in a different place but came up with errors. Where in the code should it go?

Hello wealthcig,

Thank you for your note.

I've made a simple example demonstrating where to put bool inputs like my colleague Chelsea described that should get you going in the correct direction.

Please let us know if we may be of further assistance to you.

Thanks, Kate. I have tried to input. parameters but this is what I have come up with. Attachment below. Not sure what it means

Hello wealthcig,

Thank you for your reply.

I don't see where in your script you've added the #region Properties like in the example, can you supply a screenshot of where in the script you have added these? I've highlighted that portion of the example script below:

namespace NinjaTrader.NinjaScript.Indicators
{
public class ShowLongsBoolInputExample : Indicator
{
protected override void OnStateChange()
{
if (State == State.SetDefaults)
{
Description = @"Enter the description for your new custom Indicator here.";
Name = "ShowLongsBoolInputExample";
Calculate = Calculate.OnBarClose;
IsOverlay = true;
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;
ShowLongs = true;
ShowShorts = true;
}
else if (State == State.Configure)
{
}
}

protected override void OnBarUpdate()
{
if (CurrentBar < 3)
return;

// if the last three bars have been up bars draw a green arrow up underneath the bar if ShowLongs is true
if(ShowLongs && Close[0] > Open[0] && Close[1] > Open[1] && Close[2] > Open[2])
{
Draw.ArrowUp(this, "MyArrow" + CurrentBar, true, 0, Low[0] - (2 * TickSize), Brushes.Green);
}

// if the last three bars have been down bars draw a red arrow pointing down above the bar if ShowShorts is true
if(ShowShorts && Close[0] < Open[0] && Close[1] < Open[1] && Close[2] < Open[2])
{
Draw.ArrowDown(this, "MyArrow" + CurrentBar, true, 0, High[0] + (2 * TickSize), Brushes.Red);
}

}

// properties go in #region Properties like below. Outside of OnBarUpdate but inside the strategy class.
[B]#region Properties
[NinjaScriptProperty]
[Display(Name="ShowLongs", Order=1, GroupName="Parameters")]
public bool ShowLongs
{ get; set; }

[NinjaScriptProperty]
[Display(Name="ShowShorts", Order=2, GroupName="Parameters")]
public bool ShowShorts
{ get; set; }
#endregion[/B]

}
}

Thanks in advance; I look forward to assisting you further.

Once I put it in and compile it, it disappears

Hello wealthcig,

Thank you for your reply.

You've put those in the wrong location and added additional closing curly braces to the end incorrectly.

You need to put just those lines from #region Parameters through #endregion inside the indicator class, right after the end of OnBarUpdate. I'd take another look at the example script as this illustrates exactly where those lines need to go.

Please let us know if we may be of further assistance to you.

I will give it another go. Thanks for your support on this
