Introduction
Tiger Brokers Open Platform provides API services for individual developers and institutional clients. To facilitate user access, we have developed the Open API SDK. The Open API SDK encapsulates Tiger Brokers' underlying interfaces, allowing trading programs written in a user-selected programming language (currently supporting Java/Python/C++/C#/TypeScript/Go/Rust) to conveniently call Open API interfaces to use Tiger Brokers' market data, trading, and push services. Currently, the Tiger Brokers API supports operations on all account types under the user ID, including prime accounts, global accounts, and paper trading accounts.
