Here is a screen shot of an automated system which uses synthetic trendlines and volume to trade. today: 3 trades + 9 points NO.......dont ask for the code.
P' is the right hand TL - can be drawn after 2 5 min bars V' is the envelope of volume the left hand side of a channel is determined roughly by the maximum instantaneous velocity of volume (aka pace) in the context of a rising envelope. Trend channels are the ultimate constructive diagram for trading. However -- it is only a diagram and it's up to the user to make the most of it. "To avoid the fallacies of natural language in the further process of design Alexander introduced the idea of 'constructive diagrams' as a more abstract means of representation. On the one hand these diagrams should "summarize aspects of a physical structure by presenting one of the constituent patterns of its organization" (form diagram), on the other hand the diagram "summarizes a set of functional properties or constraints" (requirement diagram). A constructive diagram is a combination of both. Each diagram describes the interacting and conflicting forces of an independent subproblem."
Look at MACD (13, 27, 9, C) on a chart with (10000V bars ). What you note is if you faded the P/V spike associated with the crossover you also bounced off the high of RTH. Nice Huh? Nice juke lower into 12:30. What does this have to do with trendlines nothing except when we broke to the upside resistance in the form of am high spanked the MACD crossover people. Thanks for the charts.
the real question is: what do you trendlines have to do with trading? you draw a line on past price, tells me nothing. anyone?
