$RIVER Damn it, set the order at 69.99, and it lost 20u immediately after opening. Just at 71.5, I didn't dare to add a short position with a fee rate of -1.2, afraid that increasing the quantity would cause a bad night's sleep again. Damn, I cut the meat and it dropped to 65.3, losing 18u. Fuck, so fierce, from 54 to 72. I should have been more confident and chased the long position. After three fluctuations, it dropped to 54, thinking it was going to crash. Who knew it would rally so hard, wasting 50 long orders that were closed at 60.
