Robot for DMarket

Sign in with Steam, add funds on a marketplace such as DMarket, and start with one or two skins that sell every day. Compare what they cost on the prices page, place a buy order under the cheapest offer, then list the skin higher once you own it. Work out the fee first, so you know the price where you break even. To save the waiting, connect the robot, which keeps your order and offer at the front while you are away.

CS2 arbitrage means buying a skin where it is cheap and selling it where it costs more. It works because every marketplace has its own buyers, sellers and fees, so the same skin has different prices at the same moment. The gap has to be bigger than the fees, and it can close while you wait for a trade hold or for a buyer, so it is never risk free. The prices page shows the same item on every marketplace side by side, with buy orders.

Flipping is buying a skin and selling it again for more, usually on the same marketplace. The common way is to buy with a buy order, which is cheaper than the lowest offer, and then to list the skin near that lowest offer. Your profit is the gap between the two, minus the fee. Only the first order in line gets filled, and only the cheapest offer sells first, which is why flippers use a bot.

This one watches the market every second. When someone outbids your buy order, it moves yours one cent above. When someone lists under your offer, it moves yours one cent below. When they leave, it moves back. It stays between the floor and the ceiling you set, and it only changes prices: you choose what to buy and what to sell.

Skins that sell often and have a wide gap between the highest buy order and the lowest offer after fees. A wide gap on a skin nobody buys can hold your money for weeks. The arbitrage tool finds the skins you can buy for less than other marketplaces price them, the most traded first.

We set no minimum: your money stays on your own marketplace account, and you can begin with a single cheap skin. The robot is free for 1 account with 1 offer and 1 order. Paid subscriptions start at $14.99 a month for 5 accounts, see subscriptions.

Yes. Prices can fall while you hold a skin, Steam's trade hold can keep you from selling it for days, and a skin may not sell at the price you hoped for. A floor stops the robot from selling too cheap, but it does not make a skin sell. We do not promise profit, and nothing here is financial advice. Start small, and only trade money you can afford to lose.

The robot works through the marketplace's API with a key you make there, and never asks for your Steam password. The key is encrypted with AES-256-GCM before it is saved and is never shown again. It can trade on your account, so make one key per account, and delete it on the marketplace whenever you want the robot to stop.

Make a key on DMarket under Settings → Trading API, one per account, and paste the secret key. It ends with its public key, which fills itself in. If you run several accounts, the robot does not treat their offers and orders as competition, so they never outbid each other.

It is DMarket's name for a buy order: the price you offer for an item. A seller can sell to you at once for that price, so the highest target gets filled first. That is usually how flippers buy under the lowest offer.
