It is important to study your mistakes. Otherwise, the trader will not be able to understand why he makes these mistakes and will repeat them again and again.
I already wrote in another topic that it is better for beginners to start with a cent account. In this case, mistakes will not lead to a sad result. On a ForexChief cent account, you can start trading with $10. This is a small deposit and the loss of this money in the event of a series of errors will not be critical.
