Edit Strategy; Custom Property Settings

[borland]

From the Strategies Tab, right clicking on any added strategy, give the menu option to "Edit Strategy....". This menu option provides a popup dialog box that allow the user the ability to change strategy parameter properties.

Instead of hard coding the trade management (order details, % stop loss, instrument, etc.), I'd like to add some custom Strategy Properties to this dialog box. Are there any Ninjascript examples showing how to do this?

Thanks, borland

Hi borland, yes - you can add user defined inputs to your scripts as shown in this tip here - http://www.ninjatrader.com/support/f...ead.php?t=5782

Thanks Bertrand!

That's a great tip. I now see it in the Tips and Tricks topic of this forum. That clarifies for the user manually entering a specific value of a parameter.

What about for parameters that the user selects from a dropdown pick list (e.g., 0, 1, 2)?

Or pick list for a bool (True, False)?

Or, further, a String case, (e.g., list of three options: "by account size", "by account quantity", "by strategy") ?

How could I modify the example for those?

 
[Description("Numbers of bars used for calculations")]
[GridCategory("Parameters")]
public int Period
{
     get { return period; }
     set { period = Math.Max(1, value); }
}

borland,

I am happy to assist you on behalf of Bertrand.

[Description("Numbers of bars used for calculations")]
[GridCategory("Parameters")]
public bool Flag
{
     get { return flag; }
     set { period = value; }
}

Is an example for a boolean.

If you need to use a drop down menu, this isn't specifically supported but some people have made such indicators. It requires a bit more object oriented programming.

I would suggest downloading such an indicator and exploring how they do it.

Please let me know if I may assist further.

Adam,

Thanks, that code example does provide a dropdown pick list for True/False. And just by changing from int to bool.

Indicators? I'm not sure you understood the topic which is modifying the 'Edit Strategy' dialog parameter options listing. I did look at the sample NT7 'Strategies' files in the File Sharing section of this forum. None of those cs files provide parameter examples using pick lists.

I will try poking some with C# Indexers, but I don't know how NT parses what's passed to switch the parameter form from entry field, to a list box.

GM borland, I think you're looking for an enum switch?
