# Real-Time Data

> Understand real-time market, order, trade, position, and account updates on DexBuilder.

DexBuilder uses WebSocket and internal real-time data services to keep DEX market and trading state up to date.

## Real-time data

* Ticker and market data
* Order book
* Market trades
* User order updates
* User trades
* Position changes
* Account balances
* Liquidation and related position-state updates

## Synchronization

The DEX loads a complete current state and then applies real-time updates. When a connection changes, it reconnects and restores the required state.
