How do you screen the whole market?
The items leaderboard takes range filters on RAP, price, copies, stock remaining, sales volume, growth and Prediction Score, over windows from one day to all time. Split it by Classic or UGC, by asset type and by sale status, and add the yes-or-no filters for Resellable and 40% Eligible.
Every screen lives in the URL, so a filter set you trust can be bookmarked or sent to someone.
How do you run a large inventory in the Reseller Terminal?
With filters and saved views, so each visit opens on a queue you built.
Filters on every field: Position, lowest price, RAP, markup, copies owned, total copies, creator stock remaining, the prices and gaps either side of you, sales per day and eligible date, each with full comparison operators.
Saved views: Store any filter and sort under a name, and star one as the default the page opens on.
Snooze conditions: Hide an item until its price or your position changes, your position crosses a number, or the lowest price crosses one.
Resell Value: Your copies priced at each item’s current lowest listing, with each item capped at ten times its RAP so one sky-high listing cannot inflate the total.
When is an undercut worth it?
Your position only means something next to how fast the item sells. Pair a Sales / Day filter with Position and your inventory splits in two: queues that will reach you on their own, where holding your price costs only time, and queues that never will.
Read the short window as well as the 30-day one. The sales count includes copies the creator sold, so an item whose creator stock drained last month can show a high 30-day rate while reselling a fraction of that today.
What does the market-wide data show?
The Market Data page tracks total value, supply, marketplace sales and free claims for Classic and UGC Limited Items back to May 2021. Its release cohorts show how much of each month’s new UGC supply has been claimed at matching ages, which is the quickest check on whether the market is still absorbing new releases before you size up launch buys.
What are other traders holding?
The Players leaderboard ranks public portfolios by value and growth, and each player page lists what that player holds. Community Favorites shows the items and creators held most widely across the site.
How do you work the Deals feed at speed?
Deals refreshes on its own and filters by discount to RAP, by RAP and by price, with separate Classic and UGC tabs. Put the items you want on your watchlist with a target price and let the alert come to you.
Can you query the market from a script or an AI agent?
Yes. RBX Invest runs a public MCP server at /mcp with read-only tools for searching and ranking items, creators and players, reading one item in depth with its resale listings, and pulling market stats. It needs no key and no registration.
Every item, creator and player page also has a Markdown version: add .md to the URL.
Which numbers should you not lean on?
Three of them mislead experienced traders as easily as new ones.
RAP on a thin item: It only moves when a copy sells, so a sold-out item with no recent sales carries an old number.
The Prediction Score after launch: It is set at release from what was known then, and it does not follow the item’s trading afterwards.
Listing prices: Anyone can list at any number. Some sit at millions of Robux for a small item and tell you nothing.
For what moved today, the daily market report in Articles lists the biggest winners and losers.
