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.
Theory is different from practicals and only when you want to have the real experience through practicals you can see the clear difference in them. Theory will teach you a lot of things and make you feel like you’re perfect in something and otherwise have that very much confidence that the market will be in your favour because of the knowledge you’ve acquired about it. The real practical of the market is the best experience you can get, because those are the time you can get the best lessons that will give you the best result and experience you can ever want to trade the market. Knowledge is important but applying that knowledge in real time is more important.
