This value cannot be calculated based on general foreign exchange profit calculations. At 14:00 on December 5th, I placed an order of 30 lots, but the original 20,000 USDT instantly turned into a loss of 20,000 USDT. Later, when I reported to the dealer, I kept pointing out our problems. Their calculation was 152 (currency difference) x 30 (lots). ) It is also impossible to reach this number, and it is speculated that it is a malicious operation. Normal platforms should have measures such as explosion-proof warehouses. My test shows that when the principal is negative, the deposit will be left and the rest will be deducted. However, this transaction kept falling and could not be controlled. Finally, a loss of 20,000 USDT occurred.
