The market lists player offers for gold, oil, uranium and boron. Buying from a listing takes only that listing at its price; a market buy walks the book from the cheapest listing up. You cannot take your own profile’s listing, and your storage needs room for what you buy.

Opening a sell listing moves the resource out of your storage into escrow. Listings never expire; they close when fully sold or withdrawn, and a withdrawn resource returns to your storage. You can have one sell listing per product; after opening, changing or withdrawing a listing for the same product, a new listing or change waits 5 minutes, while withdrawing is always instant.

A buy order sets aside quantity × price in CASH as escrow, which still counts toward wealth tax; if it fills cheaper, the difference comes back to you. Trades always happen at the waiting listing’s price. Each sale takes a 2% fee from the seller, rounded up and removed from the game: selling 500 gold at 1,000 CASH, the buyer pays 500,000 and the seller receives 490,000.

CASH can be sent directly to another player profile found by its exact name. Resource transfers only work between two profiles on your own account; GEMS and energy drinks are never transferable.
