Funding pays, the price is against you. Extended is 0.141% cheaper against HTX than usual: you would sell low and buy high (spread −0.141% now, against zero (this spread has no 7-day history yet)). If the spread goes back, that is −$14 on $10k: about 5.3 days of funding at the current rate (+$3 a day).
