Hello Mr. Tomasz Janeczko, Will it be appropriate to know about how these two Auxilliary fields will work? I should accept that every user will be expecting that his wishlist will be solved by these two New fields. I was looking forward to have TOTAL_TRADED_Value in one of these fields that would behave like Volume (So that these values would cumulate just like volume when we compress to higher timeframes like Daily, Weekly, Monthly etc.); and other users should also be having expectation of thier wishlist being fulfilled.
May be there is going to come some unexpected feature from you about these Auxilliary fields : so that every user can customise the behaviour per his/her own preference. Let's see. I will look forward to your views.
