Every row is one simulated transfer arbitrage, priced from recorded market data: bought at the real ask on the cheaper venue, held for 30 minutes while the coin would have moved on-chain, then sold at the real bid on the dearer venue. Fees, the withdrawal charge and gas are shown as separate columns, so the margin can be traced rather than taken on trust. No real orders were placed — measurement only.

The buy price is locked. In a transfer trade you commit at the moment you buy and cannot undo it. Only the sell price moves while the coin is in transit, so every row holds the buy price fixed and re-reads the sell price 30 minutes later. That is the whole question this measurement exists to answer.
Withdrawal and gas are charged in the coin, not as a percentage. They are a flat amount whatever the trade size, which is why the same price gap can lose money at 500 and make money at 25,000. Change the trade size above and watch the net column move — that behaviour is the single most important thing on this page.
Gross minus the three cost columns equals net, exactly. Coin-denominated costs are valued at the sell price, because coins lost on the way are coins that never reached the sell side.
Rows marked sell price unavailable had no fresh quote at that horizon. They are shown but excluded from every total — carrying the last known price forward would invent a result that was never observed.
