AI trading guardrails

Trade with agents that have to ask first.

Guardian is a policy layer for Alpaca trading agents. It turns a model's idea into a structured paper-trading preview, checks it against user limits, and records the result before any order is submitted.

Why Guardian

Alpaca supplies the trading rail. Guardian supplies the control layer.

Alpaca is the trading rail: account data, portfolio state, and paper order execution. Guardian is the control layer around it: policy, confirmation, and receipts.

Without Alpaca + Guardian

  • The assistant can discuss trades but has no clean execution path
  • Risk limits are hard to inspect before an order is sent
  • Portfolio context is usually stale or manually entered
  • Chat interfaces become scripts with no audit trail
  • A malformed instruction can become an unsafe workflow

With Alpaca + Guardian

  • Alpaca provides live paper account, portfolio, and order APIs
  • Guardian checks every structured TradeIntent against policy
  • Web, MCP, and Telegram all share the same guardrail engine
  • Preview and confirmation are separated before paper execution
  • Each approval, block, or submission becomes a receipt

Release stage

Paper preview

This version uses Alpaca paper trading with simulated funds. Live trading support is planned after stronger account isolation.

Agent proof

3 surfaces

The web console, Telegram bot, and MCP server all use the same policy engine.

Audit proof

Receipts

Every policy decision is recorded so the flow can be reviewed after the fact.

How it works

One paper-trading loop, three controlled surfaces

01

Agent proposes

A user or AI assistant turns an idea into a structured TradeIntent.

02

Policy decides

Guardian checks size, symbols, crypto exposure, position caps, and paper-only mode.

03

Human confirms

Approved orders still need confirmation before Alpaca paper execution.
