Event for user parameter change

[bernie_c]

Is there an event that fires when a parameter in the indicator dialog is changed?

ParamA can be any value. ParamB can never be less than ParamA. When a value is entered for ParamA that is greater than ParamB I want to Set ParamB equal to ParamA.

I found other threads about similar topics, however, none exactly like this. My guess is that this is unsupported.

Hello bernie_c,

You can call a value of a public object like a plot or int or bool from an indicator. However, you cannot have that indicator trigger an action in the script calling the indicator directly. You would need to set the value, and detect the change in the script calling the indicator.

Basically, call the indicator, save that value to a variable. Then call the indicator repeatedly and see if your variable value is equal to the indicator value. If they are not, then there has been a change.

The properties will follow this paradigm.

	[RefreshProperties(System.ComponentModel.RefreshProperties.All)]
        public int ParamA
        {
            get { return paramA; }
            set { paramA = Math.Min(1, value); }
        }

        public int ParamB
        {
            get { return paramB; }
            set { paramB = Math.Max(ParamA, value); }
        }

Exactly what I was looking for.
