So a demo is not enough , you still have to work hard and learn technical analysis to be able to trade well.
Why did you even decide that for successful trading you need to study technical analysis? This is not the first time I have met such a statement on the forum. I get the feeling that people see in all these bars and indicators on the charts a common truth, without which success cannot be achieved.
No matter how it is. I know many people (I am also one of these people) who do not use technical analysis at all, but only use graphical analysis. For example, I only need to see levels on a 1D chart. And that's all. No moving averages and other nonsense, which, in my opinion, only clutters up the chart, I don't need it. I have been trading this way for the 4th year already.
Technical analysis is just one form of analysis, and no one needs to study it to be successful in trading.
You do not "have to" have it, you should have it, there is a big difference. Just because you do not know and still made profit doesn't mean that people who know it do not make a profit neither, there are tons of people who made a profit using TA, this doesn't mean it is the only way, it just means it is a good way to make a profit. I in no way mean that if you do not know TA there is no way to make a profit, luck is the biggest part of making profit, that has always been the truth and will always stay to be the truth, without luck you can't make any profit at all no matter if you use TA or do not use TA.
However knowing it and seeing what the market is doing is a great help, most people who profit without TA just guesses the same thing, whereas people who know TA sees it, that is a big power to have. However we all could be wrong with just one tweet from Elon so it doesn't really matter.
