# Buy / Sell Collection.xyz enables the instant buying and selling of NFTs without having to wait for takers. NFT buyers can purchase NFTs that are deposited by liquidity providers; and sellers can trade their NFTs with the best bid price available from pools on Collection. One of the goals of Collection is to help buyers and sellers obtain the best price for the NFT by encouraging liquidity providers to supply liquidity based on customized filters so that more valuable NFTs get priced appropriately. Refer to the [guide](/guides/user-guides/buy-and-sell-nfts-instantly.md) on how you can execute a trade. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
