Technical analysis is far from useless. As an active trader, it's the best tool I have come across. I'm sorry, but to say that it is useless is to admit pure ignorance, or to admit your failure to grasp the concepts and understand how to apply them visually and correctly.
People do apply techniques incorrectly, yes. They can get confirmation bias from it, yes. However, that does not invalidate successful traders who trade primarily on technicals. Keep in mind that a "tool" is just that - but not used the same way by everyone - and "this means that" isn't a blanket rule that always works as described. Everything is part of a larger structural puzzle. Also, HFT algos will eat your lunch if your hold period is too short. I don't hold a position for more than a week, MAYBE two, but never less than 45 minutes - and as a retail trader, that makes a huge difference in P/L ratios over time.
Through my trading experience I have continuously used less fundamentals and more wonky technical techniques I have come up with. It has given me a massive edge over whoever is on the other side of the trade, and has pulled me quite a long way out of debt and into making a nice living doing it on the side. The side of the story that you don't see in the endless "get rich quick" trading schemes that promise to teach you all of those super awesome secrets is that anyone who knows what they're doing isn't spending any time teaching it to the masses.
But, to get back on topic: Well done with this site! It's a great beginner guide to understand what a lot of the basics actually mean. Babypips falls very short.
