Color Candles

[2Look4me]

Hi,

I'm converting NT 7 strategy to NT 8 and want the candles colored when parameters are met.
I have the following:

public class  MyStrategy    :  Strategy
{
     private bool     colorBars  = true;
.
.
.
#region Properties
        [Description("Color price bars mirrored from histogram data.")]
        [Category("Sound and Display")]
        [Gui.Design.DisplayName("Color Price Bars?")]
        public bool ColorBars
        {
            get { return colorBars; }
            set { colorBars = value; }
        }
#endregion
}

Then I'm getting the error: "The type or namespace name 'Design" does not exist in the namespace "NinjaTrader.Gui' (are you missing an assembly reference?)

What is the proper syntax for NT 8 for the candles to be colored?
Thanks

Hello,

Thank you for the post.

To create a public property I would suggest looking at how the SMA is currently formatted for the Period property. You can then just change it to a bool:

[Range(1, int.MaxValue), NinjaScriptProperty]
[Display(ResourceType = typeof(Custom.Resource), Name = "Period", GroupName = "NinjaScriptParameters", Order = 0)]
public int Period
{ get; set; }

This is the general format used for properties in NT8, you could modify it to be the following:

[NinjaScriptProperty]
[Name = "ColorBars", GroupName = "NinjaScriptParameters", Order = 0)]
public bool ColorBars
{ get; set; }

Then you can set a default in State.SetDefaults:

if (State == State.SetDefaults)
{
    ColorBars = true;

In your logic, you could then use

if(ColorBars)
{

}

To actually Color the bars, Brushes are used in NT8:

BarBrush = Brushes.Yellow;

I look forward to being of further assistance.

On the other hand, instead of creating a public property to color the candles, I have the following that colors the candles as an indicator, but it doesn't work as I apply it as a strategy. Why is that?

if(Close[0]>SMA(10)[0] && SMA(10)[0]>SMA(20)[0])
            {
                BarBrush = Brushes.Blue;
            }
            else if(Close[0]<SMA(10)[0] && SMA(10)[0]<SMA(20)[0])
            {
                BarBrush = Brushes.Yellow;
            }

Thanks

Hello 2Look4me,

Thanks for your post.

The code works in a strategy (see attached).

Do you see any errors in the control centers "log" Tab?

If not, has the strategy been "enabled"?

[2Look4me]

You are correct, the enabled box in strategies was not check marked. On the other hand I had coded

IsEnabled = true;

why that didn't apply and I have to manually do it again?

Hello,

Thank you for the reply.

Automatically enabling a strategy is currently not available. You can specify IsEnabled = true, but it is not guaranteed to enable the script as this is not a documented property. This was also not a supported property in NT7 but did enable strategies when applied.

I will add you to the feature request to support autostarting strategies.

I look forward to being of further assistance.
