If anyone thinks of a professional trader than he has never traded without S / L. I am trading myself for 3 years but I still do not like to use the tool. And of course I lost my account just because I was not in front of my PC and there was no stop loss. If someone has a very large account balance, he may think not to use S / L but if he uses large volume trading then a stop loss should actually be. I think we'd better encourage each other to use this life-saving tool in trade. From the beginning we must understand that we do not regulate and control the market. Although you might say that this is obvious and it seems we understand it - we often behave in the opposite way. In fact, every day is a challenge for traders - rumors, news, emergencies, global politics, and fundamentals can drive markets quickly and angry, and every merchant ship has to survive in this bad market stream, as long as possible.
