Judging from the current K-line, the possibility of ZK breaking through is still relatively large. Let the air force continue to short, and there is a high possibility of a sudden explosion. The strong support point is 0.185, which is stable at 0.2. It can go up after breaking through the resistance level of 0.2089-0.21. The dealer will not only let the air force make money. Be patient and let the bullet fly for a while. Soon there will be air force shouting in pain in the square. Those with principal can cover their positions near 0.190-0.192, but the bottom position must be left enough to ensure that the forced liquidation price is below 0.185-0.180.
