Quote from ElecEquity:
It's got nothing to do with hindsight bias. They exist in real time. They only matter once they're confirmed...that's when the neckline breaks.

EDIT: Yes, hindsight is a major killer in trading. It's not an appropriate label in this case. I'm not gonna argue though surf.
Absolutely untrue. After the "neckline" breaks, there is no greater odds that the move will continue or reverse, after accounting for randomness in the calculation. it's purely curve fitting and hindsight bias that allows such ridiculous claims to be asserted as truth.
The TA guy got lucky, had it moved the other way, a new definition and conclusion would have been asserted. seriously folks, you are not this naive?
