Bull market correction is a normal situation. Seize the opportunity during corrections, and only buy low, not high. Adding to a position when long is underwater is acceptable, but being stuck when short has psychological costs.

According to the Fibonacci retracement lines, assuming the previous low (0.4313) to the previous high (0.66) represents an upward wave segment, several common retracement levels can be calculated.

1. 0.236 retracement level:

0.66 - (0.66 - 0.4313) \times 0.236 = 0.6093

2. 0.382 retracement level:

0.66 - (0.66 - 0.4313) \times 0.382 = 0.5698

3. 0.5 retracement level:

0.66 - (0.66 - 0.4313) \times 0.5 = 0.5457

4. 0.618 retracement level:

0.66 - (0.66 - 0.4313) \times 0.618 = 0.5216

5. 0.786 retracement level:

0.66 - (0.66 - 0.4313) \times 0.786 = 0.4871

U-based position has been set at 0.52 for averaging down, and coin-based position at 0.52 for opening. If it drops further, I will add spot to supplement.
