Mr Black, Not quite sure if I understand your model and diagram label DOM. Here is how I interpretted your diagram on the bottom right hand corner ( the diagram that has time in the feedback loop ): The future price is determined by information from the past (inputs ie. inbalance of seller and buyers ) and the inbalance translates into now information ( volume and price ). There's a feedback loop that uses the current now information combined with the current balance of buyers and sellers that will determine the current price. The future price movement ( trend and channel projection ) is used along with past information and is reflected in the current price and the cycle keeps repeating in a continuous fashion. PAST = DEPTH OF MARKET NOW = Time and Sales date FUTURE = TREND/CHANNEL PROJECTION TIME = FEEDBACK LOOP Am I close in my understanding ? Of particular interest is your use of Time in the feedback loop. Any elaborations would be appreciated.
