$USELESS
useless upper limit looks at 0.4,
lower limit looks at space yield over ten times
Unity of knowledge and action
So I will short in batches, the initial position has been entered, moving stop-loss
Kept the additional position,
Seeking guaranteed profits before withdrawing, but big stars need a pattern,
Wish me good luck!
(Position is very important, be aggressive but take care of yourselves)
