The trailing stop for the long position of $ETH can be set at 3170, and then let it continue to rise. If it falls below 3170, exit the long position! For short positions, a 1-layer short can be entered first! Currently, there hasn't been a significant spike, as this spike is not considered large for this period, so a 1-layer short is sufficient. Then, after it comes down smoothly, implement a trailing stop to lock in the principal!
