It works. What doesn't work is making minute by minute price projections as if one is a high frequency trading platform, drawing random shapes on a chart that arbitrarily define future trajectory, and throwing around the word "profit" in post titles oh so often to imply that the benefits outweigh the risks. Plenty of technical traders out there that do well in the markets and share their thoughts/analysis openly, focusing on more longer term time frames that give a better grasp of the full picture, with a consideration of fundamentals when appropriate.
