# Multiple Accounts and API Features (Advanced)

**Multiple Account Management** Supports opening multiple sub-accounts simultaneously, suitable for strategy segmentation or team management. Users can enable the “Sub-account” function in the account center. Each sub-account has independent funds and trading records, ideal for testing different strategies or multi-user collaborative trading. The main account can transfer funds to sub-accounts, set risk controls (such as limiting max positions), manage password permissions, ensuring asset security and controllable operations.

Common uses include separate management of manual accounts, quantitative accounts, and copy-trade accounts. If you use both manual trading and bot trading, you can create accounts for different strategies separately, avoiding fund confusion and risk management chaos. It also facilitates independent statistics on profitability and risk exposure.

**API Interface Support** ChainBitX provides an open API interface, suitable for programmatic trading and third-party tool integration. Users can apply for an API Key in the account center and bind IP addresses to connect trading programs. The API supports market data subscription, automatic order placement, order query, position query, and a full set of operations.

The API can be used to connect quantitative systems, arbitrage bots, risk control monitoring platforms, etc. If you are a professional quantitative trader or institutional user, you can integrate ChainBitX into your trading engine for multi-exchange arbitrage, trend strategy execution, and more. API documentation is available on the official website’s technical support page.
