Funding between these two exchanges is close to zero, so right now this pair is about the price spread alone: SunX is 0.237% dearer against Aster than usual: you sell high and buy low, +$24 on $10k if it goes back to its 7-day average of −0.187%. The two prices were read 46 seconds apart, so part of this spread may be the market moving, not a spread.
