PTB arbitrage explained

Right now Portal to Bitcoin (PTB) trades on 7 venues we scan: 7 perpetual markets, 3 spot markets and 0 DEX pools. The lowest ask is on KuCoin perp at $0.000874 and the highest bid on Gate perp at $0.000877.

The widest PTB perpetual spread is between KuCoin and Gate: long PTB on KuCoin at $0.000874 and short on Gate at $0.000877 for +0.32% gross, or +0.16% 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 +0.229% per day, which the position collects while it is open.

For a spot–perpetual (cash-and-carry) trade, the best PTB route is to buy spot on Gate and short the perpetual on Gate: +0.30% gross, +0.10% net, with +0.259% a day of funding on the short leg.

Spot–spot PTB arbitrage (buy on Gate, withdraw, deposit and sell on KuCoin) shows 0.00% 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 PTB 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.
