What a confusing day, dizzy😵‍💫😵‍💫

My account is fine today, making a profit; my friend's account opened a short position of 100U LPT today, and the order was cut out after opening without checking. After watching the market and seeing a rise, I wanted to cover the short position, and I was confused when I opened it😂

I remember that he opened a short position of 100U, but how come the position was 1000 LPT😡😡😡, which is equivalent to the opening price of $17.3, which is a position of 17300U😓, the rise was so fierce, it almost scared me to death, and I suffered heavy losses; the highest point almost exploded, and finally I sold at a loss💔

I was nervous all day, it was really terrible😰,,
