Most retail traders cancel themselves out. It is what the industry refers to as dumb money.
Big assumption that technical analysis works. Depends on your definition of “works” and what you are using technicals for.
Technical analysis has zero predictive value, zero. Example: Trend trading. If trend trading worked as taught using technical analysis we would all be multimillionaires many times over. How many millionaires are on this board that made their money trading technical analysis? This place is, and has been for many years, overwhelmingly full of struggling and failed technical traders, an awful lot of people that eventually, slowly, faded away from trading. Where is the edge? Look at the statistics not the hype.
Technical Analysis does work well for money management.
