ETH mentioned yesterday morning that the Bollinger Bands were continuously narrowing and about to break out. In the afternoon, it broke through the 30m middle line and the market started, surging to around 2849 before perfectly retracing to the lower edge of the 30m and then rebounding. The Bollinger position is quite remarkable. If it breaks through and stabilizes at 2780, there is a chance to rebound to around 2830 to complete the bat pattern.

1-3: 3 attempts to break through the Bollinger middle line failed.

4: Effective breakthrough of the middle line, reversal signal.

5: Shark pattern at 2810, surged too quickly to around 2850.

6: The retracement position perfectly hit the lower edge of the 30m Bollinger Bands, quite precise.

7: The rebound position is the waistline position of the first wave of the surge.
