Will Caliber Engine have access to my IBKR funds?

No. Your capital stays inside your Interactive Brokers account at all times. The engine never holds, withdraws, or has custody of your money — it only sends trade instructions.

Does it work with TWS or IB Gateway?

Caliber Engine integrates through a webhook bridge that talks to IBKR's API. You do not need to keep TWS open on your machine — the bridge handles connectivity.

Can I use it on a paper IBKR account first?

Yes. Connect an IBKR paper account and watch Caliber Engine trade it exactly the way it would trade your live one. Switch to live whenever you are ready.

What instruments does it trade on IBKR?

US equities and ETFs at launch. The engine respects whatever capital and symbol limits you set on your IBKR account.

Execution pipeline

How Caliber Engine works with IBKR

Three steps from connected to autonomous on Interactive Brokers.

Step 01
Connect IBKR through a secure bridge
Caliber Engine links to your Interactive Brokers account through a webhook bridge. Your IBKR credentials stay with the bridge, your funds stay with IBKR — the engine only sends trade instructions.
Step 02
Allocate capital and risk
Choose how much of your IBKR balance the engine can deploy, set your maximum drawdown, and pick the symbol universe. Adjust or pause anytime from your dashboard.
Step 03
Hands-free execution on IBKR
Caliber Engine evaluates the market, sizes positions, manages stops, and routes orders directly to your IBKR account. You watch every decision in real time — but you never have to make one.

Advantage

Why IBKR traders choose Caliber Engine

Institutional-grade execution

IBKR's smart order routing meets an AI that decides what to trade and when. The combination is hard to beat for retail.

Lower friction, higher discipline

IBKR's tight spreads and low commissions make systematic trading actually work. The engine adds the discipline most traders lack.

No platform to babysit

TWS is powerful but it does not trade for you. Caliber Engine does — autonomously, with full visibility from your dashboard.

Your capital stays at IBKR

Caliber Engine never holds your money. Every dollar stays inside your Interactive Brokers account, where it already is.

In detail

Built for the most powerful retail brokerage

Interactive Brokers is the broker most professional retail traders end up at — for good reason. The execution is institutional, the costs are low, and the API is robust. The catch is that IBKR does not trade for you. Caliber Engine fills that gap with an autonomous AI engine, powered by Anthropic Claude, that reads market regime, evaluates probability, sizes positions, and manages risk on your behalf.

Once you connect IBKR through the bridge, the engine handles the entire trade lifecycle: scanning the universe, deciding when to act, opening positions, setting stops, taking partial profits, trailing the runner, and closing out. Each outcome is logged so the engine's next decision benefits from the last one. You see every trade in your dashboard, but you do not need to approve any of them — the engine runs autonomously inside the limits you set.

If you already trust Interactive Brokers with your capital, Caliber Engine is the most natural way to scale your trading without scaling your screen time.
