A few days ago, after my account was liquidated, I consider it a lesson bought with money. When trading contracts, you must set stop-losses; it's better to lose a little than to risk your principal. If you protect your principal and continue to listen to Brother Deng, step by step, there is a high probability you can recover your losses. 😎 If you approach contract trading with the mindset of guaranteed victory, you are no different from a gambler. After a loss, I would rather slowly make it back bit by bit.
