The first-hand transaction of Shanghai Aluminum is about 6w5, and the deposit needs about 1w3. The copper transaction is about 20w, and the deposit needs about 2w. The main metal contract positions exceeded 6.5438+0.6 million lots, and the margin on that day increased by 2 percentage points. The margin requirement for aluminum and zinc is higher than that for copper.

Unlike stocks, futures can be operated in Man Cang for a long time, because futures are leverage and easy to explode. For example, there is only 2w in your account. But you bought a lot of copper for the night. As a result, Shanghai Copper opened lower by 1 1,000 points the next day due to the sharp drop in the external market, so your floating loss is1w. If you don't make up the deposit, your funds will not be enough to hold the minimum deposit, and you will be forced to close your position. Floating loss 1w is a loss of 50% for your 2w principal, so you have to have enough funds to hold positions. Another way is short-term intraday trading, which can be operated in Man Cang during the day, but the position should be closed regardless of the ups and downs before closing. This avoids the risk of overnight operation, and the risk of daily operation is basically controllable.
