About
Composer is a next-generation automated trading and investment platform that combines AI strategy creation, no-code editing, backtesting, and fully automated execution — all in one place. Users can describe their investment goals or risk preferences in plain English, and Composer's AI-assisted editor will generate a ready-to-deploy trading strategy, called a 'symphony.' The no-code visual editor allows investors to customize any strategy by swapping assets, adding conditional logic (if/then rules), applying custom weighting schemes (equal weight, inverse volatility, market cap), and filtering asset pools dynamically. Once a strategy is built, Composer's backtesting engine compares performance against benchmarks, models fees and slippage, and visualizes historical allocation shifts over time. Execution is fully automated — Composer handles rebalancing and order placement on your behalf. The platform also features a Community marketplace where users can discover, remix, and invest in strategies created by other traders. Composer acts as the brokerage directly, offering zero commissions on trades, no management fees, and support for Traditional and Roth IRA retirement accounts. With over $28B in trading volume and 15M+ orders executed, it is purpose-built for retail investors and self-directed traders who want systematic, data-driven investing without writing a single line of code.
