Buy on the cheapest market, sell on the priciest — each price is that market's lowest listing. Fees are on by default, so Buy shows what you actually pay and Sell what you actually receive after the venue's cut; ROI and profit are net. Untick With fees to compare raw listing prices instead. The two sliders cover the full range currently on offer, and there is no hidden max-ROI cap — only isolated broken listings are dropped, so genuinely cheap buys are kept. Manage which markets exist sitewide on the Markets page.
