I have been unable to set the stop loss in the transaction, how can I do a good stop loss?

Why set a stop loss!

Who spread the operation of stop loss? Think carefully about where did your stop loss money go? Who most wants you to set a stop loss? Let me just say that every transaction you make is with your platform provider. You are the counterparty. If you use this platform, you are only qualified to do transactions with this platform. Every long order you make The platform merchants are selling to you, and every empty order you make is bought by the platform, which means that the platform earns all the money you lose. Of course, every take profit you make is also a loss for the platform. But in the end you always lose money, why? Because everyone is using the theories, technologies, and methods created and disseminated by the platform to form their own trading systems. These theoretical and technical methods themselves are conspiracy. It is strange that a trading system based on such factors can make money!

Stop loss is the biggest lie in the market. Those who take the maxim of cutting losses and letting profits run as a golden rule are destined to be losers in the market.
