Observe the process of breaking through the target area t1-t3 to see if it is a big force. If it is a slow decline in the direction of 5 o'clock, you can still go back and forth as a consolidation; if it is a waterfall, first place the price limit target area. Extreme market conditions are often 3-3 in one minute. With a fluctuation range of 10%, it is often too late to place an order and the transaction cannot be made at a good price. At present, the downward space is opening up little by little, and the short side has the upper hand. Once the breakout is pushed, the decline may accelerate.
