Most people just learn the basic of trading which is just executing trade, but this isn't enough to be a successful margin trader if not you keep loosing funds, you have to learn about chart patterns, know how to analyze trade, know how to read candles. With this knowledge of technical analysis you could actually know when to enter and leave the market, like it's said no one can actually know the direction of the market! I might be new but with my studies I can say technically analysis could help to predict the market to an extent. Trading futures without knowledge of technical analysis is just like gambling because you don't know the next movement your just trading based on luck
Why would anyone call himself a trader if he has not learnt how to analyse trade, read candles or understand chart patterns? Technical analysis is the most important thing to learn if you'd become a successful trader.
I've seen people ( i wouldn't call them traders) who skip technical analysis only to end up losing funds because all of their trades are just mere gambling.
If truly you intend to make profits trading, then you should make out to learn all there is to technical analysis. It's very important even more than fundamental analysis which some people believe is more important
