The price spread pays, funding is against you. Bybit is 0.149% dearer against Extended than usual: you sell high and buy low (spread +0.149% now, against zero (this spread has no 7-day history yet)): +$15 on $10k if it goes back. Holding the pair costs −$28 a day in funding at the current rate, which eats that in about 13 hours.
