I have defined the Darvas Series as: DarvasSeries1: TDarvasSeries; I am adding data into the Darvas Series using: DarvasSeries1.AddOHLC(ADate,AOpen,AHigh,ALow,AClo...

How do I find the top and bottom of a darvas box? That is, I want to develop additional logic based on whether a new value will be within or outside a particular Darvas box.
