For systematic traders who build their own logic
Research, test and execute through code on the same infrastructure used by Clear Street's institutional clients.
A modern low latency API backed by institutional infrastructure
Traders used to choose between a clean API from a small broker or the infrastructure and balance sheet of an institutional firm. Clear Street offers both.
Built on rails we own
Clear Street builds and operates the execution, clearing, custody and financing infrastructure underneath your account.
Built for developers
Modern developer tooling designed to get you from idea to first trade without fighting slow APIs, complex integrations or legacy developer tooling.
API Access to OMNI
Clear Street Omni is fully accessible via our API and SDKs. You can implement Omni AI questions and responses into your research or execution workflows.
Control how orders execute
Choose the order type and the route, from trailing stops to TWAP, VWAP and DMA, with pre-trade risk checks before anything reaches the market.
One account, every surface
The API, the MCP server, TradingView and the Clear Street app are all available with the same account.
Regulated and well capitalized
Your account is held at Clear Street LLC, a broker-dealer and member of FINRA and SIPC, registered with the CFTC as a Futures Commission Merchant.
