What does Composer do?

Composer is an automated trading platform that lets you build, backtest, and execute trading algorithms without writing code. You create trading strategies called 'symphonies' using a visual editor and AI, then run them automatically across stocks, ETFs, crypto, and options.

Who is Composer best for?

Composer is best for traders and investors who want to automate their trading strategies, test them against historical data, or follow strategies created by other users in the community, without needing programming skills.

Do I need to install anything to use Composer?

No, you don't need to install anything. Composer is a web-based platform that you access through your browser at composer.trade.

Is Composer free to use?

Composer offers a free tier with limited features, but it does not allow live trading. To actually execute your strategies, you need Composer Pro at $30/month, which gives you unlimited automated trading across all accounts.

Does Composer offer an API or integrations?

Composer is powered by Alpaca's Broker API and uses BMO Harris for custody of investments. The search results do not specify whether Composer offers its own public API or third-party integrations.
