How Caliber Engine works with Topstep
Three steps from a Topstep account to disciplined autonomous execution.
Connect your Topstep account
Link your Trading Combine or funded Express Account through a webhook bridge that supports futures order entry. Your account stays with Topstep.
Configure for Topstep's rules
Set your daily loss limit, max loss limit, contract caps, and consistency targets. The engine treats them as hard constraints — no overrides.
Hands-free, rule-aware execution
Caliber Engine scans, decides, sizes, and manages every trade autonomously. You watch every decision in real time from your dashboard.
Why Topstep traders choose Caliber Engine
Built around your max loss limit
The engine treats your max loss limit as a hard floor. As you approach it, sizing reduces or stops. No overrides.
Consistency without effort
Topstep rewards consistency. The engine delivers it by default — same setup criteria, same sizing, every trade.
No emotion, no revenge trades
Most Combines fail after one bad trade triggers another. The engine has no emotion to recover from.
Pause anytime, disconnect anytime
You stay in control. Pause when you hit your daily target, disconnect when you want to trade manually.
Designed to respect Topstep's Trading Combine rules
The Topstep Trading Combine and funded Express Accounts have well-defined rules: daily loss limits, max loss limits, scaling plans, and consistency targets. Most Combine attempts fail because traders break those rules under emotional pressure. Caliber Engine is built to make those rule violations functionally impossible. You configure your daily loss, max loss, and consistency targets on signup. The engine cannot exceed them.
Powered by Anthropic Claude, the engine evaluates each setup before acting, sizes contracts to your account size, manages stops with discipline, and takes partial profits to lock in gains. Every outcome is logged. The engine's next decision benefits from the last one. The result is a trading process that does not panic, does not revenge-trade, and does not chase setups outside its plan.
Caliber Engine is designed to comply with Topstep's published rules at the time of writing. Topstep updates its rules from time to time. Always verify your account's current rules with Topstep directly before connecting any automated system. Caliber Engine is not affiliated with Topstep, and cannot guarantee passing any Trading Combine or funded account.
