How to invoke a file selector in parameters section

[vlc]

I would like to allow for a .wav file to be selected from the file-system instead of just asking for a string. How do I change the following snippet to allow the user to select the .wav file from the file system?

[Description("Please select a wav file")]
[Category("Alert")]
public string buySignal
{
get { return buySignal; }
set { buySignal= value; }
}

Hello vlc,

Thank you for your post.

This would be possible through C#, you can find an example at the following link: http://ninjatrader.com/support/forum...t=36162&page=2
