Never lose a Roblox tradeagain.

Values and RAP come from the Rolimons item API, which is the community reference for Roblox limiteds. The catalogue is refreshed hourly. Roblox itself does not publish item values, so these are community estimates rather than official prices.

RAP (recent average price) is calculated from actual recent sales, so it always exists but lags the market and can be manipulated. Value is a figure the Rolimons value team assigns to items they track — roughly a fifth of the catalogue. Where an item has a value, the calculator prices it on value; otherwise it falls back to RAP and tells you it did.

A projected item is one whose RAP has been pushed up by manipulated sales — traders buying and reselling to themselves to fake a higher price. The calculator prices projected items 25% below list, because that inflated number is not what you will get when you try to trade it on.

Each side is priced at value (or RAP), weighted by Rolimons demand and trend ratings where they exist, discounted if projected, then reduced by 3.5% per extra item on that side up to 25%. The percentage is the gap between the two adjusted sides. Anything inside ±5% is treated as fair.

Yes. The full Rolimons catalogue of 2,500+ limiteds is searchable by name or acronym — typing "DC" finds Domino Crown. The whole index is loaded once and searched on your device, so results appear as you type with no waiting.

Yes. Copy trade link puts the whole trade in the URL, so anyone who opens it sees the same items on both sides. One-for-one trades produce a short link using the two asset ids.
