Composer review
A visual, no-code strategy builder with backtesting and automated trading for stocks and ETFs.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Composer lets individuals and businesses create investment strategies, called symphonies, with a no-code visual editor or AI-assisted tools. Users can define weights, filters, and conditional rules, then backtest against historical prices and compare results with benchmarks or other strategies. Approved strategies can trade and rebalance automatically through Composer brokerage accounts. A community library supports discovering, inspecting, editing, and investing in shared strategies. Its focus is a fit for people who want to build rule-based approaches without writing code, rather than investors seeking broad asset-class coverage.
The free Starter plan allows unlimited strategy building and backtesting, with a limit of up to 200 nodes per strategy and automation for one strategy. Advanced costs $10 per month and raises the limit to 350 nodes while allowing automation of up to five strategies; it also includes more weekly Trade with AI usage. Pro costs $40 monthly or $384 annually, with up to 500 automated strategies, up to 10,000 nodes per strategy, and full API access. Business pricing is quote-based; its listed capabilities include strategy building, mark-to-market accounting, business portfolios across markets, and API access. The tiers primarily distinguish automation scale and strategy complexity.
Composer’s tools cover the full strategy workflow from visual construction and AI-assisted discovery to historical allocation views, backtest cost estimates, benchmarking, and automated trading. Alpaca Securities and Apex Clearing are listed integrations, and API access supports data retrieval, backtests, and trading on Pro. Coverage is centered on stocks and ETFs: support for direct crypto assets and crypto indicators ended January 31, 2026. That makes Composer less suitable for strategies requiring crypto exposure or broader asset-class selection. Choose it if no-code strategy design and automation are the priority; consider alternatives if your approach depends on assets outside its stated coverage.
