Freeze 3600 at first, and then deduct 6400.
When the price falls, the frozen funds will be reduced, and when it falls to 2300, only 2760 will be frozen. Your account should have 3600-2760 = 840, plus 6400, which equals 7240. After deducting the loss of 7000 yuan, 240 yuan should still have funds available.
