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.

• Net spread = (best bid on the sell exchange − best ask on the buy exchange) ÷ best ask − taker fees.
• Spot routes pay one taker fee on each exchange and require moving coins between exchanges or holding inventory on both. The Transfer column shows the cheapest open network, its withdrawal fee and the trade size where that fee equals the spread, or why the coin cannot move right now.
• Perpetual routes need no transfer: long on the cheaper exchange, short on the more expensive one, and close both when prices converge. They pay two taker fees on each exchange, and funding payments apply while the positions are open.
• Max profit is read from both order books: we buy up the asks and sell into the bids until the next level stops paying, and show the size where profit peaks. Routes we have not read yet show the size at the best price only, marked top.
• Only markets with at least $100K of 24h volume, a book spread under 2% and quotes updated in the last 60 seconds are compared, and both quotes must be taken within 15 seconds of each other. Spreads above 20% are dropped as likely different tokens sharing a ticker.
