Yes, I think all the advice you have given is important for everyone to know in trading. I have understood all the words you have mentioned here for a long time. However, trading is a very risky business. To be successful here, experience is definitely needed. Without experience, success cannot be achieved in the trading platform. Moreover, you have mentioned here that indicators do not play a big role in understanding trading, but I think understanding indicators in the trading platform will play an important role in the success of a trader in the trading platform. Maybe we cannot analyze indicators in trading platforms very much, but those who are professional traders trade on trading platforms based on indicators and create success, they never trade without following indicators. We may face losses in the trading platform because we do not understand the indicators and trade.
Trading is definitely not as simple as buying low and selling high. Knowledge, experience, analytical skills really determine a person's success in trading and not all traders can do it the right way. Most traders may only prioritize feelings because they think prices will increase due to several reasons, some others may only rely on fundamentals, including positive news. It's up to how they trade, but what is certain is that trading carries a risk of loss which requires every trader to consider everything wisely.
