For a spot–perpetual (cash-and-carry) trade, the best SIGN route is to buy spot on Bybit and short the perpetual on OKX: +0.07% gross, -0.13% net, with +0.030% a day of funding on the short leg.
Spot–spot SIGN arbitrage (buy on Bybit, withdraw, deposit and sell on Gate) 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 SIGN 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.
