The widest XAUT perpetual spread is between HTX and Gate: long XAUT on HTX at $4,158.11 and short on Gate at $4,163.70 for +0.13% gross, or -0.03% after the 0.16% two-leg fee model. No transfer is needed: both positions stay on their exchanges until the prices converge. The funding difference on this pair is -0.015% per day, which the position pays while it is open.
For a spot–perpetual (cash-and-carry) trade, the best XAUT route is to buy spot on Binance and short the perpetual on Gate: +0.07% gross, -0.13% net.
Spot–spot XAUT arbitrage (buy on Binance, withdraw, deposit and sell on Bitget) shows +0.02% gross right now. It only works if withdrawals on the buying exchange and deposits on the selling exchange are open, so check the D/W dots before moving coins.
Small XAUT gaps usually disappear after fees, slippage and funding. Look at the Net column, the executable Depth and the spread history before trading: a gap that has been open for days is a different trade from a one-minute spike.
