TypeConverter for strategies?

[edstaffin]

Hi,
In the Pivots.cs example indicator there is a TypeConverter attribute set to allow hiding and showing of properties based on the selected value of an enum property.

I want to do the same type of thing in my strategy. In other words, in the strategy analyzer I want to hide and show certain properties/settings based on values set in other properties/settings by the user.

According to the notes in pivots.cs:
// When creating a custom type converter for indicators it must inherit
// from NinjaTrader.NinjaScript.IndicatorBaseConverter to work correctly with indicators

There does not appear to be a NinjaTrader.NinjaScript.StrategyBaseConverter.

Any tips or examples of how to get this type of functionality going in a strategy would be GREATLY appreciated and worth at least 2 Snickers bars.

Thanks ... Ed

Hi,
Thanks, but it doesn't address the issue:

Hello,

I've just tested the code that Baruch posted via his link, and it does work as expected in NinjaTrader 8 after slight modifications for initialization and such. I've attached a NinjaTrader 8 version for your review. In the Strategies window, toggling the ShowA and ShowB properties will show or hide the InputA and InputB properties in the properties grid.

Do you see the same thing on your end with this version?

Edit:: I've just double-checked to make sure this will work with enums, as well, and it appears that it does. I added the following to the attached code:

public enum myEnum
        {
            myEnumA = 0,
            myEnumB = 1,
        };

        myEnum showAEnum;

        [Description("Show or hide A")]
        // [GridCategory("Parameters")]
        [RefreshProperties(RefreshProperties.All)]
        public myEnum MyEnum
        {
            get { return showAEnum; }
            set
            {
                showAEnum = value;
                    if(showAEnum == myEnum.myEnumA)
                        {
                         showA = true;   
                        }
               }
        }

would be GREATLY appreciated and worth at least 2 Snickers bars.

I think it's only fair that Baruch and I split the Snickers bars. Thank you.
