Composer Alternatives That Track and Analyze, Not Trade
Composer is a genuinely strong product for people who want to automate a strategy and actually run it. It builds algorithmic trading strategies, or symphonies, and executes them in a linked brokerage account, with rebalancing handled for you. If your goal is to put a rules-based strategy into the market and let it trade, Composer does that well. It is also US-gated and centered on stocks and ETFs rather than crypto. Indexes is deliberately a different thing: it is informational and educational, track-and-analyze not trade. You build a weighted index from stocks and crypto together, backtest it against real market history, and track it over time versus benchmarks like the S&P 500 and BTC. It never connects to a brokerage, never places a trade, and is self-serve and globally accessible.

In short
Composer is an automated trading platform: you assemble a rules-based strategy, called a symphony, and Composer executes and rebalances it inside a linked brokerage account. It is built to put a strategy into the market and let it trade, and it is centered on US stocks and ETFs. Indexes is not that. It never links a brokerage, never places a trade, and never holds money. It is the design and measurement step: you author a weighted index of stocks and crypto together, backtest it against real market history, and track it against the S&P 500 or BTC. If you want automated execution, Composer is the right category. If you want to construct and study an index without trading, that is what Indexes is for.

Questions
Composer and Indexes, answered
What is Composer?
Composer is an automated investing platform where you build rules-based strategies, known as symphonies, and it trades and rebalances them for you inside a connected brokerage account. It is aimed at people who want algorithmic strategies executed automatically, primarily across US stocks and ETFs, rather than at manual index construction.
Does Composer place real trades?
Yes. Composer connects to a brokerage account and executes the strategy for you, including rebalancing. That automated execution is the core of the product. Indexes works the opposite way: it never connects to a brokerage and never places a trade, so it is analysis and design only, not a place your money moves.
Is there a Composer alternative that does not trade?
Yes. If you want to design and study an index rather than automate trades, Indexes is that alternative. You build a weighted index of stocks or crypto, backtest it against real market history, and track it against a benchmark, with no account to fund, no minimum, and no orders ever sent. It stays informational and educational.
Can I build a custom index instead of a trading strategy?
That is exactly the Indexes use case. Rather than encoding entry and exit rules for automated trading, you define an index: which stocks or tokens are members, how they are weighted, and how often it rebalances. Then you backtest the construction and follow the level over time as a living, named index.

Build your index and see how it backtests
Bundle stocks or crypto into your own weighted index, backtest it against real market history, and track it against the S&P 500 or BTC. Prosumer pricing, no brokerage account. Indexes is educational and informational only, and it never places a trade. Decide for yourself.
