Funding pays, the price is against you. Extended is 0.099% cheaper against Bybit than usual: you would sell low and buy high (spread −0.099% now, against zero (this spread has no 7-day history yet)). If the spread goes back, that is −$10 on $10k: about 8.2 days of funding at the current rate (+$1 a day).
