What is the difference between AI trading and algo trading?

Algo trading (or expert advisors) uses pre-programmed rules to place trades automatically on your behalf. AI trading with an assistant like Chelsea is different: you make every decision through a conversation with your AI assistant, and the assistant executes your instructions. AI trading does not run automatically, does not trade on signals, and does not act without a prompt. It is closer to a voice-or-text interface for manual trading than to an automated trading system.
