Caliber Engine for Rithmic.
Rithmic is the data and execution backbone behind many of the fastest futures accounts in retail. Caliber Engine is the autonomous AI engine that uses that backbone to trade your futures strategy — disciplined, hands-free, and always inside the limits you set.
How Caliber Engine works with Rithmic
Three steps from a Rithmic-powered account to autonomous futures execution.
Connect your Rithmic-powered account
Link your Rithmic-powered futures account through a secure webhook bridge that supports Rithmic execution. Your account stays with your broker — the engine only sends instructions.
Set contract sizing and risk
Tell the engine how many contracts to size into, your daily loss limits, and your max position size. The engine treats them as hard rules — no overrides.
Low-latency autonomous execution
Caliber Engine scans, evaluates, sizes, and routes orders through Rithmic on your behalf. Every decision logged in real time.
Why Rithmic users choose Caliber Engine
Speed plus discipline
Rithmic delivers institutional-grade latency. Caliber Engine delivers institutional-grade discipline. The combination is hard to beat for retail futures.
No charts to babysit
Stop staring at the order book. The engine watches the market for you and only acts when its setup criteria are met.
Hard risk limits
Daily loss limits, max position size, max contracts — the engine enforces them mechanically so a bad day cannot become a blown account.
Your account stays yours
Caliber Engine never holds your funds. Everything stays inside the brokerage account behind your Rithmic connection.
Built for futures traders who care about execution quality
Rithmic is the execution and market data layer behind many of the most serious retail futures accounts. The advantage is speed and reliability. The trade-off is that Rithmic alone does not give you a strategy — and trading futures with the speed Rithmic enables also means trading at the speed at which mistakes compound.
Caliber Engine pairs Rithmic-grade execution with an autonomous AI engine, powered by Anthropic Claude, that reasons about each setup before acting, sizes contracts to your account, manages stops with discipline, and logs every outcome so the next decision benefits from the last. The engine cannot trade outside the daily loss, position size, and contract limits you configure on signup.
If you already trust Rithmic with your data and execution, Caliber Engine is the most natural way to scale your futures trading without scaling your screen time.
