I have another question. For example, if you opened a long position at 2600, with a forced liquidation at 2500, and then you opened a short position at 2600 to hedge, the price drops to 2500. You close the short position and make 100 points, but your long position is still at a loss. However, because you made 100 on the short, your forced liquidation price moves from 2500 to 2400. What should you do if the price continues to drop? Should you open a short position at 2500 to continue hedging, or should you add to your long position to move the 2600 long down to 2500? If you move the long down to 2500, then the forced liquidation price will also move from 2400 to 2500, unless you continue to add margin to push the forced liquidation down.
