The specific calculation is as follows:
(Settlement price 220 yuan/gram)
Right of the day = 100000-40000-240 = 59760
First deposit: 220×1000×10% = 22000.
The number of contracts for forced liquidation is: 4-59760÷22000= about 1.3 (hands).
Round up =2 hands.
Answer: You need to draw two hands.
Let strong parity 220 yuan/gram.
Then the investor's rights and interests are: 59760-60×2=59640 (yuan).
