Funding between these two exchanges is close to zero, so right now this pair is about the price spread alone: KuCoin is 0.041% cheaper against SunX than usual: you would sell low and buy high, −$4 on $10k if it goes back to its 7-day average of −0.113%. The two prices were read 54 seconds apart, so part of this spread may be the market moving, not a spread.
