#COAI Those who profit from shorting must exit before the settlement fee rate, preferably 5 minutes in advance, because the closer it gets to settlement, the more they pump, likely to prevent short orders from exiting. After the settlement fee rate, then enter short again, even if it means earning a bit less, you can't let the platform take your fees. Also, if you make a profit, be sure to set a trailing stop loss to protect your capital first.
