if technical analysis "doesn't work", is there something else that does? And what do we even mean by "doesn't work"?
A simple example, not actual numbers;
I look at the amount of time I put into researching the markets, time in front of the charts, and ultimately return on investment. If the S&P 500 is returning 10% for example, and my trading is returning 8% then I am not successful. I may be profitable, but not successful by my standard. I can invest in the S&P making more money with no effort.
And I need enough return to be compensated for my time. Am I more profitable committing my time to another activity? That is passively investing in the S&P at 10% while generating other income with my time. Quality of life plays a part as well. I don’t like sitting in front of the charts all day. Others may have different criteria to fit their purpose.
What I find successful is a combination of fundamentals and technicals. Fundamentals provide valuable information on what to trade, why and in what direction, or if you should trade at all. Once my trading decisions have been made, then I turn to technicals which are valuable in the management of the trade. Technicals are used to determine entries, exits, targets and so on. Technicals are not used to make the decision to trade.
