Composer

What is Composer?

Composer is an automated trading platform and investment app. It enables users to build, backtest, and execute AI-powered trading algorithms without needing to code. The platform handles fully automated trading execution and account management, all under a single subscription.

Application scenarios

AI-assisted strategy creation: Users describe investment goals in plain English to generate a custom trading algorithm.
Automated portfolio management: Investors set a strategy and let the platform execute trades and rebalances automatically.
Strategy discovery and replication: Traders browse, invest in, or modify pre-built strategies from community and curated categories.
Tax-smart retirement investing: Users employ automated, active trading strategies within tax-advantaged accounts like Traditional and Roth IRAs.
Visual strategy editing: Individuals use a no-code editor to customize logic, conditions, and asset weightings in any strategy.

Main features

AI-powered strategy creation: Explain your investment goals and risk concerns in natural language, and the AI-assisted editor builds a strategy for you.
Fully automated execution: Composer acts as the brokerage, automatically making trades and rebalancing your portfolio based on your strategy.
Pre-built strategy library: Discover and invest in ready-made strategies across categories like Long Term, Technology Focus, and Diversification.
No-code visual editor: Modify any strategy or create your own from scratch using a visual interface, without writing code.
Programmatic logic rules: Build conditional trading rules (e.g., "If the 20-day return of SPY is >2%, then buy SPY; if not, buy BND").
Portfolio weighting options: Apply custom weight, inverse volatility, market cap weighting, or equal balancing to assets in your strategy.
Community strategy sharing: Publish your strategies to the community, or invest directly in and remix strategies created by other users.

Tax-advantaged account support: Run automated strategies in retirement accounts like Traditional and Roth IRAs, with potential transfer fee coverage.

Target users

Composer benefits retail investors and traders who want algorithmic trading strategies but lack coding expertise. It's suited for individuals seeking automated portfolio management, those interested in testing or replicating data-driven strategies, and investors looking to implement active, tax-smart strategies in their retirement accounts.

How to use Composer?

Visit the official website to get started. You can create and fund your brokerage account directly within the app. Begin by using the AI editor to describe a strategy goal or by browsing the library of pre-built "symphonies." Use the visual editor to customize your strategy's logic and holdings, then let the platform execute and manage trades automatically.

Pricing and free trial

The platform operates on a simple fixed monthly subscription model called a Trading Pass. This pass unlocks unlimited automated trading across all accounts. The site mentions a free test is available. It notes zero commissions and zero management fees, but advises that other fees may apply and users should consult the full fee schedule.

Effect review

The platform presents a streamlined approach to algorithmic trading by removing the coding barrier. The core proposition is practical: translate an investment thesis into an executable, automated strategy through conversation or visual editing. For the target user, the value lies in automation and access to systematic trading methods that would typically require significant technical skill or capital to implement elsewhere. The integration of brokerage services and retirement account support suggests a design focused on consolidating the entire trade lifecycle, from idea to execution, within one ecosystem.
