For the first layer of the position held at $ETH , the most important thing is your follow-up strategy. Currently, if this position rebounds, you can directly set a trailing stop to lock in your capital. If the upper resistance is not broken, it will drop again. It is only at 3620 that you should add to your third layer of position. If entering at 136, there is currently no need for a stop loss. After entering the three layers, then apply a stop loss. If the position of the three layers is also broken, the trend will shift!
