I think I understand why this topic got created. With the answers from here, people want to get proof or enough answers that "professional traders dont lose money", so they would start trading and learning such profitable profession. People still search for magic solution, magic button that closes all deal with profit. But I will disappoint people who are looking for such answer, conclusion or proof - professional traders are the same traders, they just make at profession and do it more frequent, and also lose money.
