This number comes from the average of the best (highest) bid and (lowest) offer. To affirm the fairness of this price, we might also check the recent trade prices.

This section covers querying the live order book and accessing price data. By interacting with the SDEX's public [Horizon endpoints](../../../data/horizon/api-reference/resources/README.mdx), you can obtain real-time market data and make informed trading decisions. While Stellar provides transparent access to price information, external oracles can also be used when integrating with other systems or when off-chain data is required.
The Stellar network takes a crowdsourced approach to liquidity. Namely, the SDEX gives all users equal access to a global decentralized order book for any pair of assets on he network. Since launching with the genesis of the Stellar network in 2014, the SDEX has processed over 4.2 billion trades worth upwards of \$25 billion.

Let's pretend you just got paid in Mexican Pesos, but you'd prefer to hold your savings in U.S. Dollars. After querying the [exchange rate](#reading-prices), we can send a new offer to the network, swapping Pesos for Dollars at our desired rate. By submitting a sell offer that matches the current market price, we can ensure our pesos are converted to dollars promptly.
