TAC arbitrage explained
Right now TAC trades on 8 venues we scan: 7 perpetual markets, 3 spot markets and 0 DEX pools. The lowest ask is on Gate perp at $0.001533 and the highest bid on MEXC perp at $0.001534.
The widest TAC perpetual spread is between Gate and Binance: long TAC on Gate at $0.001533 and short on Binance at $0.001534 for +0.07% gross, or -0.09% 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 -0.065% per day, which the position pays while it is open.
For a spot–perpetual (cash-and-carry) trade, the best TAC route is to buy spot on Bitget and short the perpetual on Binance: +0.07% gross, -0.13% net, with +0.093% a day of funding on the short leg.
Spot–spot TAC arbitrage (buy on MEXC, withdraw, deposit and sell on Bitget) shows -0.20% 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 TAC 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.
