Everything a trader needs
Live prices where Steam doesn't show them
CS2 Trader adds pricing information directly into Steam inventories and trade offers, so you always know what an item — or a whole trade — is actually worth before you accept.
- Total inventory value and per-item pricing in every Steam inventory.
- Trade offer values on both sides, with profit shown for incoming offers — sortable by most profitable first.
- Multiple pricing providers to choose from, plus "starting at" price and sales volume info.
- See the original currency and price an item was listed for on the Community Market.
Floats, phases, and technical data
Skin value depends on far more than the exterior label. The extension surfaces the technical details traders actually price by:
- Float values, paint index, paint seed, and pattern index in inventories, trade offers, and on the market.
- Doppler phases, fade percentages, and marble fade patterns (fire and ice, blue tip, red tip…).
- Float rank data — see when a skin is e.g. the 5th lowest float in existence.
- Order market listings by float value and load more than the default 10 listings.
- "Inspect in Browser" button on the market, in inventories, and in trade offers — no game launch needed.
Faster trading workflow
Beyond data, CS2 Trader automates the tedious parts of Steam trading:
- Trade-lock countdowns on every item, with bookmarks and notifications when an item becomes tradable.
- Mass listing and selling of items on the Community Market.
- Instant accept / decline buttons on the incoming trade offers page.
- Add all similar items or a whole inventory page to a trade in one click.
- Sort inventories and trade offers by price, tradability, name, or position.
Trade safer
The extension also helps you avoid the scams that plague CS2 trading:
- SteamRep-banned scammers are flagged on their profiles and inside trade offers.
- Known spam and scam comments (fake giveaways and the like) are reported automatically.
- Copy a user's permanent profile link — scammers often rotate their custom URLs.
- Set rules for incoming friend requests: accept, ignore, or block on matching conditions.
