There was a low price of 38.279 between 5:30 am and 6:15 am on November 18, 2020. After I woke up, I found my margin cccount blasted. However, on another platform, people's orders, same as me, were normal, and they left the market under Stop-Profit. I checked the international oil price that day, and did not find such a low price. Hope that all the investors keep their eyes open and stay away from traps.
