Just out of interest, I'm wondering what aspects of T/A people think are rubbish?
Topping the list for me is fibonacci numbers. Yes, I know NR who knows more about trading than I will EVER know in my entire lifetime believes in them. But to me it is rubbish. Fibonacci ratios are basically derived from adding the two previous numbers in a sequence. 1,1,2,3,5,8,... To think these really have any magical significance over future price increases/declines is absurd.
It is like the 'more twins are born during a full moon' fallacy. When the midwife sees twins, s/he looks out the window and says 'ah yes, it is a blue moon' or otherwise, doesn't register the lack of a full moon. Only the blue moons are remembered, and so the belief is augmented.
Unfortunately for my rational argument, it doesn't really matter. If you can derive a positive expectancy from believing in fib ratios, who cares?
