User defined Variables: Font? Enum Pull-Down list?

[Lost Trader]

Can anyone help me figure out how to pass a Font through an indicator's input parameter list? It's possible, because chart properties has a font as an input, including its associated sub-variables (type, size...).

Also, how to get a pull-down for a fixed enumerated list (for example plot line styles - there's a fixed set from which user selects using a pull-down). How do I add parameters like that to my indicator?

The wizard doesn't help for these non-numeric variables. Fixing that would be a good solution as well.

Are there ANY examples? I am happy to plagarize from a sample....

Thanks!!

Got parameter enum pull-down worked out

OK, I figured out how to get a pull-down list. The properties methods already recognize existing NT variables such as the TextPosition used by DrawTextFixed() so those are EASY. Now I still need a sample of passing in a complete font as an input parameter.

Example for
private TextPosition volPosition = TextPosition.TopRight;

[Description("Position of text message in the panel")]
[Category("Text")]
[NinjaTrader.Gui.Design.DisplayName("Text position")]
public TextPosition GetDTFPosition
{
get { return volPosition; }
set { volPosition = value; }
}

For a custom list, it would be very similar:

public enum SillyNames
{
Harri,
HoHum,
Horrid,
}
private SillyNames you = SillyNames.Harri;


public SillyNames GetName
{
get { return you; }
set { you = value; }
}

Getting a font parameter is just a matter of using C#. You can try looking into the MSDN to see if you can find anything there.

Example Font input variable

Here is an example of passing in a complete font as an input parameter.

Example for
private Font fv = new Font("Arial", 10, GraphicsUnit.Point);

[XmlIgnore()]
[Description("Font of the text message")]
[Category("Custom")]
[NinjaTrader.Gui.Design.DisplayName("Text font")]
public Font Text_Font
{
get { return fv; }
set { fv = value; }
}
[Browsable(false)]
public string Text_FontSerialize
{
get { return NinjaTrader.Gui.Design.SerializableFont.ToString(f v); }
set { fv = NinjaTrader.Gui.Design.SerializableFont.FromString (value); }
}

The variable type 'Font' MUST have a capital 'F'

the XmlIgnore line and serialize method are required to avoid errors when saving the chart template, and so that the indicator will REMEMBER changes.

Thanks LostTrader, that helps. I put your suggestions to good use. Thank you for sharing them.

Customizing and Saving parameters as defaults

1. Is it possible to capture parameters in a Strategy in NT6.5 and save them as defaults so the user does not have to re-enter them everytime the strategy is used?

For example, I have a strategy in which the user may enter a personal sound wave file, but how can it be saved permanently?

2. How can I create category areas in NT6.5, and not have to have all my parameters under the "Parameters" category?
I tried using [NinjaTrader.Gui.Design.DisplayName("Sample Category Area")], but it does not create a new area, like it is possible in NT7.

rperez,

1. This is unfortunately not supported in 6.5

2. To create a new category just setup your properties under the desired new category name - i.e.

 
[Description("Period for slow MA")]
[Category("MA Periods")]
public int Slow
{
get { return slow; }
set { slow = Math.Max(1, value); }
}

Thanks Betrand,

1. Too bad
2. I've tried that, but it doesn't work. When I name my categories, the corresponding parameters simply do not appear in the Parameters Window.

The attached code shows a parameter that dissapeared when I set the new category name.

[Description("Print debugging control messages to the 'output window'?")]
[Gui.Design.DisplayName ("1. Performance: Print debugging breaks to the 'output window'? ")]

[Category("Performance")]
public bool ImprimirResultadosParciales
{
get { return imprimirResultadosParciales; }
set { imprimirResultadosParciales = value; }
}

rperez, could not reproduce here on 6.5 - works for me - where are you testing? In the Strategy Analyzer?

Thanks

[rperez]

No Bertrand, in a strategy I coded and am running now live (sim).

[NinjaTrader_Bertrand]

You're right, on the chart you would unfortunately only see Parameters, on the SA and Strategies tab you should see also the custom ones.

[rperez]

So, the'res no way in NT6.5 to add new categories to the running strategies?

[NinjaTrader_Bertrand]

None that I'm aware of unfortunately, we added support for this with NT7.

How about this problem.

How to serialized time parameter?. How to create/serialized an audio file?. A drop-down list of audio file? Anyone could help me on this problem.

[NinjaTrader_Bertrand]

Unfortunately this is outside of the scope we can support here, however for enums in general this should be handy - http://geekswithblogs.net/claeyskurt.../19/85667.aspx
