Guides

Place, modify and cancel an order Place an order in one or many broker accounts, change its price or quantity, cancel it and check its status.
Protect a position Put a stop-loss and target on a position: held at your broker (GTT or stop order) where it can be, or watched by Cirrus.
Price and indicator alerts Get told when a price, a tick field or an indicator crosses a level, on Telegram, in the app or at your webhook.
Entry trigger with a bracket Wait for a price or condition to enter, then manage the trade with a target, a stop-loss and a trailing stop.
Multiple targets (ladder) Book profit in steps: exit part of a position at each target and move the stop-loss up as each one is hit.
Loss limits, profit lock and targets Stop trading for the day at a loss limit, lock in profit once it reaches a level, or exit everything at a profit target.
Automated strategies Write a strategy, backtest it on past days, run it on paper accounts, then take it live.
Webhooks and notifications Get a signed HTTPS call when orders, trades, positions or triggers change, verify it, and choose what reaches Telegram.
The live stream Open one WebSocket and get your orders, positions, holdings and funds as they change, without polling.
Errors, rate limits and retries Every error code and what to do about it, the rate limits, and how Idempotency-Key makes retries safe.
OAuth for partner apps Build an app other Cirrus users connect to their accounts: authorization code with PKCE, tokens, refresh and revocation.
Build with AI Rules files for coding agents (Claude Code, Codex, Cursor, Copilot and more).
Connect an AI agent Connect Claude, ChatGPT, Cursor and other AI clients to your account over MCP, with limits you set.
