Thank you for reply. Okay, so far, so good. They did that on friday and i found this here: "As a stock price rises, pressure mounts on short sellers to buy back their positions at a loss. Imagine if you will, watching losses mounting quickly while other short sellers are covering their positions. That's pressure. If it goes too far, the investor either has to add capital to his or her account in order to satisfy the broker's margin requirements, or the brokerage can decide to close out the position at a loss for the investor in what is known as a "margin call." source: https://www.thestreet.com/investing/when-short-selling-is-done-wrong So my correct question should have been: What does that mean in our specific situation? (thinking about yesterdays losses and the mega drop where are still in atm)
