How to Vet an Agentic Trading Tool
A practical checklist for evaluating AI trading agents: custody, guardrails, execution rails, transparency, and costs — before you connect your brokerage.
Not every "AI trading tool" is agentic, and not every agentic tool is safe to connect to a brokerage. This checklist is the one we apply before listing a tool here — and the one you should apply before using one.
1. Who holds custody?
The safest pattern is non-custodial: the AI can place orders, but the money stays at your broker. If a tool wants to hold funds itself, treat that as a major red flag and read the terms carefully.
2. Are there real guardrails?
- Daily or per-trade limits — can you cap what the agent can do?
- Approval gates — can you review before execution, or approve once and walk away?
- Position/sector exposure caps — can the agent over-concentrate a portfolio?
- Audit trail — is every agent action logged and reviewable?
3. What are the execution rails?
Agentic tools fall into two buckets. Bring-your-own-agent (MCP): the broker exposes a Model Context Protocol server and you supply the model — flexible, but the responsibility is yours. In-app agents: the broker/product ships the agent itself with guardrails built in.
4. Does it actually execute?
Check the tool's docs: does it place real orders, or only recommend them? Screeners, signal engines, and research copilots are useful — but they are not agentic. If the term "agentic" appears but there is no order placement, it is marketing.
5. What does it cost?
Look for: monthly subscription, per-execution fees, spreads, or data fees. Compare against the value of the automation. Freemium tools are a good way to test in paper trading first.
6. Paper trading first
Every credible agentic tool offers a paper or sandbox mode. Run the agent there for weeks before linking a funded account. If a tool does not offer paper trading, walk away.
Frequently asked questions
What should I check before connecting an AI trading agent to my brokerage?
Check who holds custody (prefer non-custodial, where money stays at your broker), whether real guardrails exist (daily or per-trade limits, approval gates, position caps, audit trail), what the execution rails are, whether it actually places orders, and what it costs.
Is it safe to let an AI trading agent place orders?
Only with hard guardrails: dedicated accounts, funding limits, approval gates, exposure caps, and a logged audit trail. Test in paper trading for weeks before linking a funded account.
What is the difference between bring-your-own-agent (MCP) and in-app agents?
Bring-your-own-agent (MCP) means the broker exposes a Model Context Protocol server and you supply the model — flexible but your responsibility. In-app agents are shipped by the broker or product with guardrails built into the interface.
Do all agentic trading tools offer paper trading?
Every credible agentic tool offers a paper or sandbox mode. Run the agent there for weeks before linking a funded account. If a tool does not offer paper trading, treat that as a reason to walk away.
