According to your Jinbao dealer's description, contracts with the same quantity and different directions are called warehouse locking (that is, one hand is empty, and one hand is multiple).
Locking the position is considered as an operation skill and a kind of self-protection. Investors often lock positions when they lose money.
Then unlock it. It is suggested to close the profit sheet first and continue to hold the loss sheet. (Unlocking: some platforms need to meet the relevant margin); Recently, the price of gold has been in a weak position, mainly due to the strength of the US dollar, which may continue for some time. If you can suggest not to close the position first, when the price of gold drops to 1 100 USD/oz, close the position and hold more than one position. I hope I can help you!
