AI agent trading: how autonomous trading agents work, and how to keep them safe
An AI trading agent is software that decides and acts on its own: it gathers information, forms a view, and places trades without a person approving each one. That autonomy is the risk. A safe setup never lets the agent itself decide how much it may lose. Hard limits, key permissions and a kill switch sit outside the agent, where it cannot change them.
What is an AI trading agent?
A trading bot runs a fixed strategy. An AI trading agent has more freedom: it can read data or news, choose among actions, and adapt what it does, sometimes using a large language model to reason about what it sees. Agent trading is the practice of letting one or more of these agents trade an account, usually each with its own strategy or market.
Risks that are specific to agents
- Acting outside your intent. An agent optimising for a goal may take trades you never meant to allow.
- Bad inputs. A wrong data feed or a model that misreads a headline leads to confident, wrong trades.
- Prompt injection. An agent that reads web pages or posts can be steered by text planted in them.
- Runaway loops. An agent that retries or averages down can repeat a losing action very fast.
- No clear record. Without a log, it’s hard to know why the agent did what it did.
Guardrails that keep an agent inside your limits
- Trade-only keys. The agent can place orders but can never withdraw. See API key safety.
- A risk check outside the agent. Every order the agent proposes goes through a separate, deterministic check against your loss, drawdown, position and exposure limits. The agent can ask; it can’t override.
- A budget per agent. Each agent gets its own capital and caps, so one bad agent can’t drain the account.
- A kill switch. One control halts every agent at once. See how it works.
- Paper first. Agents trade live data with simulated fills until they pass a fixed bar.
- An audit log. Every proposal, approval, rejection and halt is recorded where it can’t be quietly edited. Try the audit-chain demo.
How AI Trading Fleet runs agents
AI Trading Fleet is a fleet of strategy agents, each working one market or approach. Agents only propose orders. A pure risk function, with no network access and no randomness, decides whether each order goes through, using limits you set. The agents can’t change those limits, the key can’t withdraw, and the kill switch stops every agent at once. Agents whose forecasts lose calibration are demoted automatically.
Questions
What is the difference between a trading bot and an AI trading agent?
A trading bot follows a fixed strategy. An AI trading agent can gather information, choose between actions and adapt, often using a trained model to decide. More freedom means more need for limits the agent cannot change.
Can an AI agent trade crypto for me?
Yes. It connects to your exchange through an API key and places orders. Use a trade-only key with withdrawals disabled, and set loss limits that are enforced outside the agent.
Is it safe to let an AI agent trade my account?
Only with guardrails the agent can’t override: trade-only keys, hard loss and position limits checked on every order, a kill switch and a full audit log. Even then, trading can lose money.
Can AI agents trade on Polymarket and Kalshi?
Yes. Both have APIs, and AI Trading Fleet runs agents on Polymarket and Kalshi from launch, inside limits you set.
