It was of my interest to look into this in order to break away from short term trading as my goal is to set trades at a maximum of once a day and/or a close of once a day.
Unless you study diligently, there will probably be no insight into how this chart has been produced.
Key levels according to number with the integral retrace 1/3 to move 2/3 in the opposite direction is what will predict the price high as well as where the major turns will be. If accurate, we are looking to close long around Midday on Tuesday this week.
