Composer
#1 Tradingby Composer Technologies · Best for automated strategies
Composer is an AI-powered trading platform that turns plain-English ideas into automated strategies — called symphonies — that it backtests against historical data and then executes and rebalances automatically across stocks, ETFs, and options. There is no coding, no per-trade commission, and no management fee; you pay a flat Trading Pass subscription. It is the most accessible way to run rules-based, emotion-free automated trading from a regular brokerage account.

How Composer works
Composer reframes trading as building a 'symphony' — a visual decision tree of conditional rules (if SPY is above its 200-day moving average, hold equities; otherwise rotate to bonds) that the platform executes automatically. Its AI assistant lets you describe a goal in plain English and turns it into an editable strategy, so you get the discipline of algorithmic trading without writing any code.
Every strategy can be backtested against historical market data before you commit real money, which is the platform's core safeguard: you see how a rule set would have behaved through past drawdowns rather than guessing. Once live, Composer places the trades and rebalances on your schedule across stocks, ETFs, and options, removing the emotional, in-the-moment decisions that hurt most retail traders.
Pricing is a flat Trading Pass — $24/month billed annually (or $32 month-to-month) — with no per-trade commissions and no management fee, after a 14-day free trial. Because it is a fixed subscription rather than a percentage of assets, the economics favor larger or active accounts; very small balances may not justify the monthly cost.

Composer FAQ
How much does Composer cost?
Composer's Trading Pass is $24/month when billed annually, or $32/month month-to-month, with a 14-day free trial. There are no per-trade commissions and no management fees — the flat subscription unlocks unlimited automated trading across your connected accounts.
Do you need to know how to code to use Composer?
No. Composer is built for no-code users: you assemble strategies visually as conditional rules, or describe what you want in plain English and let its AI draft an editable strategy. No programming or quantitative-finance background is required to build, backtest, or run automated trades.
Is Composer safe and regulated?
Composer executes trades through a regulated US brokerage account, and you keep full control to pause or edit any strategy. It does not guarantee returns — automated strategies can still lose money — so backtesting and starting with modest amounts are the recommended safeguards.
What can Composer trade?
Composer automates strategies across US stocks, ETFs, and options. It builds, backtests, executes, and rebalances rules-based portfolios automatically, making it suited to systematic, hands-off investing rather than discretionary day trading or crypto.
