Custom Component shall implement few simple interfaces. Every class for export shall be marked with Exportable attribute. It is made to simplify developer’s work – if there are several classes in library developer can manage their exportability.

To access attribute and other types for SDK you need to use Commons.dll from ProTrader root directory.

namespace com.pfsoft.proftrading.commons.external 
{ 
    /// <summary> 
    /// Use this attribute for allow/forbid export designed 
    /// component to application 
    /// </summary> 
    [AttributeUsage(AttributeTargets.Class, AllowMultiple = false, Inherited 
= false)] 
    [Serializable] 
    public class ExportableAttribute : Attribute 
    { 
        private bool FExportable; 
        public bool Exportable 
        { 
            get { return FExportable; } 
        } 
 
        public ExportableAttribute(bool isExportable) 
        { 
            FExportable = isExportable; 
        } 
        public ExportableAttribute() 
            : this(true) 
        { 
        } 
    } 
}
