Brokerage API
The programmatic interface a broker exposes for placing orders, reading positions, and streaming account data. Platforms integrate these APIs so users don't have to: authentication, order lifecycle, error handling, and reconciliation all live behind one adapter per broker. API capability differences (order types, fractional support) shape what strategies can deploy where.

Backtests are hypothetical, computed by DeployQuant's engine on minute-resolution consolidated US market data (2021-01-04 to 2026-07-17, $10,000 starting capital, no margin, fees and slippage not modeled) and do not guarantee future results. Nothing on this page is investment advice. Live trading involves risk of loss.
