## Why close_position is rated Critical

Closing a trading position directly moves money by executing a sell/buy transaction at market price, which is a financial action. It cannot be undone once executed in the market. This falls under Financial (most severe category) with critical severity because an AI agent misusing this tool could close positions at inopportune times, causing significant financial losses.

From the tool's own definition: "'Close a position by ticket number' — closing a trading position is a financial operation that executes a market transaction, locking in profits or losses and committing financial obligations irreversibly."

## Use case

AI agents use close_position to commit financial operations through MCP Trader Server, usually the final step of a payment, billing, or trading workflow. A call moves real money.

## Recommended policy (PolicyLayer)
