1, a short position is like an enterprise being insolvent. Gold and silver are different from stocks, a bit like futures. You can use leverage to multiply your profits, and of course your losses will multiply. If you have a deposit of 100 yuan in your account, you can buy gold and silver from 500 yuan with five times leverage. When the market price drops by more than 20%, the value of gold and silver you bought from 500 yuan shrinks by more than 100 yuan, which exceeds the deposit amount in your account. At this time, your account will burst. The trading rules stipulate that it's no use if you don't sell it. Just when your margin is not enough to cover the loss, you are closed (that is, forced to sell).

2, the explosion of positions at sea is a popular saying: that is, you originally booked a position, and suddenly for various reasons, the shipping company told you, sorry, now the ship is full, please wait for the next ship.
