Quote from tradingjournals:
Good chart BMW! My analysis tells me that 3400 is likely a top, so what we see is probably a topping process. When I look at the rise from 3330 area towards the 3400, I see a possible nonlinear price-time curve with a negative second derivative. So a non linear curve such as A+Bt +CT^2 could give more information. If one were to look at the changes in price and time measured from the 3330 bottom, one then get A to be zero by looking at price changes and counting time starting at the bar when prices started to rise.
BWM: could you please post the excel file containing your numbers?
Anyone else: Could I suggest that we get the A, B and C. SQRT(ABS(B/2C)) should tell us where would the price peak?
Some might say why do we discuss something non linear when the lines are the focus of this thread? I would say it is true that lines could be fine as long as one can analyze time as continuous (as DB reiterated a number of times, and he is right to do that), but one could also analyze it as non-line curves such as the curve I suggested above. This would allow one to see the picture at a higher level. Demand-Supply waves do not always travel in a constant angle. They could also go sideways, or follow a non linear curve. Think of the example of a rock thrown upward. The trajectory could be viewed as many pieces of lines with decreasing slops over time, but also as an A +Bt + Ct^2.
