Frequently asked questions
Does Composer use AI to build strategies?
Yes. Composer’s Create with AI accepts a natural-language prompt, builds a symphony, and runs a backtest. Users can also edit the rules in its visual Editor. CommonQuant likewise generates inspectable strategy rules from plain-English descriptions.
Can I automate trading with both platforms?
Composer can execute symphonies through its brokerage. CommonQuant generates, backtests, monitors, and alerts on strategies, but does not execute trades; users act through their own broker. A backtest on either platform does not guarantee live results.
