1. The initial deposit for each contract is $2,000, and that for two contracts is $4,000. If the maintenance deposit is calculated by 75%, then the maintenance deposit is $4,000 * 75% = $3,000.
2. In April 1, the price of Swiss francs bought was 0.44 USD, but it fell to 0.435 USD on April 26th, so the loss of 1 contract was 125000*(0.44-0.435)=625 USD, and the loss of two contracts was/kloc-0.
3. The initial investment is $4,000 (customer's equity), the security deposit is $3,000, and the available funds are $65,438+0,000. So when the Swiss franc fell to 0.435 USD on April 26th, the customer's rights and interests became 4,000 USD-1.250 = 2,750, which was not enough to maintain the positions of two contracts, so at least 250 USD was added.
