Quote from tommo:
Im not trying to make an argument one way or another just passing on my observations.
I have been a professional trader for 7 years. And not just trading from home i mean on trading floors with hundreds traders .Ive never known one of them make money from technical analysis. Some of them dont even have charts. People will be aware of things like where there might be some support line etc. But most of the edges are far more specific in trading .Reading an algo in the order book, reacting to news releases, arbitrage strategies etc. My own personal experiences, the only time i had a losing year was when i tried running some technical systems( and yes i had good risk management, only risked 1% of account, followed system religiously etc etc)
I am not saying it cant be done, i want to make that clear. I guess im just not very good at it, but ive been around the block a bit, thought my comment might be of some interest.
