No transfer is needed: both positions stay on their exchanges until the prices converge. The funding difference on this pair is +0.073% per day, which the position collects while it is open.
For a spot–perpetual (cash-and-carry) trade, the best GMT route is to buy spot on OKX and short the perpetual on Bitget: -0.05% gross, -0.25% net, with +0.030% a day of funding on the short leg.
Spot–spot GMT arbitrage (buy on OKX, withdraw, deposit and sell on Gate) shows +0.36% 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 GMT 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.
