    Multi-option drop down parameters

    How do i specify multiple options with drop down/combo box type parameter?

    Similar to EntryHandling parameter.

    This can be done by declaring an enum within your strategy. If you are not familiar with this C# concept I would suggest leaving it for now. This is outside of what we support however, I will provide sample code on how this can be done in the near future.

      Excellent, I'm familiar with it.

      heres an example for anyone else
      Code:
      public enum PosTypes {Long, Short} // be sure to make this public
      
      PosTypes posType = PosTypes.Long;
      
              [Description("Pos Type")]
              [Category("Parameters")]
              public PosTypes PosType
              {
                  get { return posType; }
                  set { posType = value }
              }

        FYI: There already is an equivalent NT enum: NinjaTrader.Cbi.MarketPosition.

            Hm, that's interesting. Is there also such a class for relational operators? (<,>,>=,etc)

            I was just wondering, because I'm making an indicator, and would like to include a drop-down menu with various relational operators so that the user can choose how the condition should be tested. For example with such an drop-down menu it would be possible for the user to choose between 'Variable1 > Variable2' condition and the 'Variable1 < Variable2' condition.

            How can I achieve such a feature with enums? (or perhaps a different way?)

            Any thoughts are highly appreciated

            Regards,

              J_o_s, I'm not aware of one for relational operators, I would suggest you create an enum case for either scenario you would need to express your potential conditions.
