A decentralized cryptocurrency exchange is built on a blockchain and uses distributed ledgers to allow peer-to-peer exchange and trading of digital assets via smart contracts. User's funds are held in their personal wallet and they get to keep their private keys.
Most of DEXs charge low fees between 0.1% - 0.25% per trade and some charge no fee for market makers. Some of these exchanges use Lighting Network, atomic swaps and other technologies that facilitate cross-chain transactions.

Basically, a user places an order using their wallet by interfacing with the website, or or trading programmatically using the API. The platform will then relay this information to the Ethereum blockchain through the 0x protocol and the the latter uses smart contract to complete the order on the blockchain.
As a relayer, it crafts order book from cryptographically signed messages from liquidity providers or market makers who are willing to sell their assets for a given time period. A liquid taker or market taker accesses the order book and agrees to trade with the maker under specific conditions. The order is then filled through the 0x protocol.

For instance, using Lumens, the platform allows a user from one blockchain with EUR balance to trade with another with USD balance all without any need for conversions. It matches the two orders based on Lumens.
The advantage of this is that those with fiat do not need to convert them into Lumens or any other cryptocurrencies to participate in trade when they only need a different fiat currency on a cryptocurrency exchange. It also allows users to keep their digital assets in whichever currency they will because it is easy to make the conversion.
Otherwise, the platform is basically a matching order system that completes a taker order when a matching maker order is made. The order will cancel when a matching order is not found. A user can also look on the order book to select the best rate of conversion for his or her assets at any time.
