Let me tell you something! The on-site transaction is completely closed, which is not only not free, but also has huge prepayment and deposit procedures. However, people are not forced to participate. Usually, they attend training and complete exams. They have a certificate code, according to which they decide whether to enter the market or not. Some teaching materials and simulation software may be free, or some platforms provide download and trial, but there is no access to actual data and no cash transaction in the capital system.
