Hello everyone, I would like to ask you how to become a stable profit trader, what aspects should be learned from it, I have read some books, such as price behavior, but still at a loss in the real market 
Hmmm, to be honest, there is no way to become a stable profit trader. Because it has a high volatile nature. When the nature of a thing is based on volatility, it is very difficult to find stability in it. So if someone imagines that stable profit is organized in trading, then it is not so. Trading is the riskiest way of profit. If you misunderstand something even a little bit, then of course you have 100% risk of loss.You have to master things like good skill, right time entry, market dynamics, etc., to make the rest of trading risk less. And finally, let's say that the best thing in trading is to follow the trend. Someone has said that "Trend is your Friend".
So by learning these things, you can stabilize your trading a little bit, but the market has no trust, you should be careful all the time.
