The best option to be more confident is to have enough experience. To do this, I tried to work longer on the demo account of the Amarkets broker in order to have more experience and knowledge.
I think you need to have good confidence before doing anything. If you don't have any confidence before doing anything, you will never be successful. Think carefully before doing anything. Once he starts, he should never pull back from him.
When you gain enough knowledge about trading, your confidence level will increase. Most of the traders who have been trading in the market for a long time have come to the market with trading knowledge before taking entry into live trading. If you come to trading in the market with confidence without knowing well about the market, then it will become over confidence. So you have no other option to enter the market with confidence.
