The lesson we learn from trading experience and articles we read are quite different, though the lesson from both are very important in trading but the mistakes of some beginners, they get much confidence in trading after learning only from books.
Experience gives the best lessons to traders, which beginners should never be in haste or be so confidence to trade with big amount of money by only gaining knowledge from reading books about trading.
There are many indicators and discussions about trading and there may also be many strategies shared by people in different articles but when we run them sometimes they don't match the trading situation we are doing.
Experience will be formed when someone is involved in trading and if you rely on learning it will not provide direct experience.
Experience can be achieved by getting involved in it with and using smaller money so that we can learn directly and
managing risk is very important in trading so that we don't get caught up in expectations that are greater than reality.
Learning from books or anywhere is fine as long as we can study strategies that are much more effective and by getting directly involved will provide a much better experience slowly.
