Technical analysis is fortune telling. It is crap. More than that, it is a scam. You can't tell anything about the future by looking at the charts that happened in the past. It is gambler's fallacy. Just because you lost 20 times, doesn't mean you are going to win the 21st game. It is always about the fundamentals. If the fundamentals are crap, the rest has no meaning at all. The price can go up and down just because somebody wanted it to. It don't have to make any sense.
I think we can't do without both as a professional trader and if we eventually miss one of the two then we might end up making a heavy loses which is detrimental as a trader. We need to understand that technical analysis involves candle stick pattern, indicators and other things we need to know as a trader apart from the major news that can move the market.
