AI Trading Agent Security & Risk Checklist

Before connecting an AI agent to a brokerage or exchange account, limit what it can do. Grant the narrowest API permissions and never withdrawals. Cap order size and daily loss, keep a tested kill switch and human approval for anything new, and log every action. Treat any outside text the agent reads as untrusted input.

Work through this list before granting trading permission, and again whenever you change the agent's strategy, tools or provider.

Account and API keys

  • Use a separate account or sub-account holding only the capital the agent may trade.
  • Create a key with trade permission only. Never enable withdrawals or transfers.
  • Restrict the key to known IP addresses if your broker or exchange supports it.
  • Turn on two-factor authentication for the account itself.
  • Never paste keys into chat tools, shared documents or code repositories.
  • Rotate keys periodically, and know how to revoke one immediately.

Limits the agent cannot override

  • Maximum size per order and maximum position per instrument.
  • Daily and weekly loss limits that stop trading when hit.
  • An allowlist of instruments. Anything outside it is rejected.
  • Where possible, enforce limits at the broker or in separate code, not in the agent's own instructions, which it may misread or be talked out of.

Human control

  • Start in approval mode: the agent proposes, you confirm each order.
  • Test the kill switch before going live. It should cancel open orders and stop new ones.
  • Get an alert for every order sent, filled or rejected.
  • Require human sign-off before any new strategy or larger limit takes effect.

Agent behavior and prompt injection

  • Assume any text the agent reads (news, filings, web pages, emails, social posts) could contain instructions written to manipulate it. OWASP ranks prompt injection among the top risks for language-model applications.
  • Give the agent only the tools the task needs. A research agent doesn't need order access.
  • Make sure the agent cannot edit its own limits, permissions or instructions.
  • Keep a complete log: inputs, reasoning where available, tool calls and orders.

Data and privacy

  • Find out where your keys are stored and whether they are encrypted.
  • Ask what account and trade data the provider keeps, for how long, and whether it's used to train models.
  • Confirm you can delete your data and revoke access when you leave.

Provider due diligence

  • Identify the legal company, its country, and who runs it.
  • If it manages money or pools funds, confirm registration with the relevant regulator.
  • Look for published security documentation and an incident history.
  • Reject promises of guaranteed or very high returns. The CFTC names these as fraud warning signs.

Frequently asked questions

Is a read-only key safe to share?

It can't trade or withdraw, but it still exposes your balances and history. Share it only with providers you trust with that data.

Should an agent ever have withdrawal permission?

For a trading agent, there's no need for it. Withdrawal permission turns any compromise of the agent or its provider into a direct loss.
