S arbitrage explained
Right now Sonic (S) trades on 10 venues we scan: 10 perpetual markets, 7 spot markets and 0 DEX pools. The lowest ask is on Gate perp at $0.0416 and the highest bid on Bybit spot at $0.0417.
The widest S perpetual spread is between Gate and MEXC: long S on Gate at $0.0416 and short on MEXC at $0.0416 for +0.12% gross, or -0.04% 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 +0.020% per day, which the position collects while it is open.
For a spot–perpetual (cash-and-carry) trade, the best S route is to buy spot on Binance and short the perpetual on MEXC: -0.17% gross, -0.37% net, with +0.030% a day of funding on the short leg.
Spot–spot S arbitrage (buy on Binance, withdraw, deposit and sell on Bybit) 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 S 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.
