Overview

Composer by SoFi is an automated trading platform and investment app for building, testing, and executing trading strategies in one place. The site describes it as a brokerage-based product with a no-code editor, AI-assisted strategy creation, backtesting, and automatic trade execution.

It is designed for people who want to create rule-based or AI-assisted trading strategies without coding, then fund an account and let the platform handle trades and rebalancing. The pricing and retirement pages also show support for trading across account types, including individual, retirement, and business workflows.

Features

AI-assisted strategy creation

Describe a trading idea in natural language and Composer’s AI-assisted editor can generate a strategy draft for you.

No-code strategy editor

Use the no-code visual editor to build strategies from scratch or modify existing symphonies without writing code.

Backtesting and strategy comparison

Test strategies against benchmarks and compare performance before you execute them.

Automated execution and rebalancing

Let Composer place trades and rebalance automatically once a strategy is funded and active.

Strategy sharing and community publishing

Share strategies with others so they can test them, remix them, or invest in them directly.

API access and account options

Use the Composer API to pull data and trade stocks and ETFs, and manage individual, retirement, or business account workflows where supported.

Use Cases

  • Designing a strategy without coding

    Create a trading strategy from a plain-language prompt, then refine the allocation, logic, and parameters in the editor before testing it.

  • Testing ideas before execution

    Compare a strategy against a benchmark or another strategy, review return and risk metrics, and iterate before funding it.

  • Automating an active portfolio

    Set up a funded account and let Composer handle order placement and rebalancing automatically as the market changes.

  • Managing retirement trading

    Build or hold retirement investments in Traditional, Roth, or Rollover IRA accounts while using automated trading rules.

  • Operating strategies for a business entity

    Use the business account offering to build diversified algorithmic strategies with API access and real-time, data-driven portfolio management.
