The empty order of $ETH can take profit when a new needle appears near 3310, and then start to buy at 136! Once again, I remind you that buying at 136 three times only accounts for ten percent of the principal, and each time you buy, the point difference must be 100 points. If it does not continue to fall and goes straight up, start using a trailing stop to lock in profits! So, the allocation of positions must be done well!
