Together, before fees−0.403%−$40 on $10k · with fees, hour by hour

The price spread sits at its 7-day average of −0.102%, so right now this pair is about funding alone: −$11 a day on $10k at the current rate. The two prices were read 50 seconds apart, so part of this spread may be the market moving, not a spread.
