The time when it is easiest to lose money in a bull market has come. At this time, it is easy for you to short and the callback will end and then explode. If you get off the bus, you may not have a chance to get on the bus. If you don't get off the bus, you may keep falling and your profits from the previous period will be gone. It is recommended that you hold the spot and leave immediately when the contract takes a bite. Don't fight to the end.
