2. "Do you close your position at 100% or at the opening price?" The answer is at the opening price. Based on the above reasons, there is no deal at 100%.

3. In fact, many platforms did not forcibly close their positions when they reached 100%. You will usually be given a margin period, after which you will be forced to close your position. Take MIG as an example, when the margin ratio reaches 2%, you will be forced to close your position and give you an additional margin for one week.
