## Frequently asked questions

### Is there a US100 arbitrage opportunity right now?

No. The best US100 routes do not cover taker fees at the moment.

### Which exchange has the cheapest US100?

Lowest ask price: Perpetual: OKX at 30,817.

### How is the net spread calculated?

Net spread = (best bid on the sell exchange − best ask on the buy exchange) ÷ best ask − taker fees. Spot routes pay one taker fee per exchange. Perpetual routes pay two per exchange, to open and to close. Max profit is read from both order books, so it includes slippage, and spot routes also subtract the withdrawal fee.
