Interactive Brokers API reliability as an engineered service: the IBKR session behind your automated trading becomes observable, recoverable and auditable — in your own Azure tenant, on your own account, with your IB Key in your hands.
Interactive Brokers API reliability is not a hardware problem. The TWS API is a socket into a Java application that must stay logged in, restart daily and re-authenticate weekly. Everything below is documented behaviour, not bad luck — and none of it is fixed by a bigger VPS.
Miss the IB Key prompt by three minutes and the login needs a human. Log into IBKR Mobile with the API username and the gateway session dies. Sunday needs a full shutdown.

Engineer, deploy and run the reliability layer around your IB Gateway and strategy host.
Lines we do not cross — because your broker agreement, your regulator and your investors would not want us to.
Azure Lighthouse lets us operate the deployment from our tenant while your Key Vault stays out of reach: the delegation is control-plane only and cannot carry Owner or data-plane roles. The VM reads the IBKR credentials with its own managed identity. We cannot.
Every tier is fixed-price with a binary acceptance criterion. Deploy and Run are sold only after an Audit — the same four-gate discipline we apply to our own trading systems. Prices are indicative, in USD, and invoiced by RocketEdge.com Pte. Ltd. or RocketEdge.com LLC depending on your jurisdiction.
Read-only review of your live IBKR stack against 12 laws and 174 rules: gateway settings, IBC configuration, reconnect handling, order-reference scheme, data staleness, calendars, access control, cloud posture. Includes the connectivity-tier decision: Gateway, Web API OAuth or FIX.
A scored report (0–100), a gap register ranked by blast radius and a fixed quote for Deploy — or a written recommendation to stop.
The reference architecture in your Azure subscription from infrastructure-as-code: gateway container, reliability agent, dashboards, alert ladder, Key Vault, backups, runbooks and your first operational due-diligence pack. Warm standby on a second username available.
Ten consecutive trading days with every indicator green or every red correctly alarmed, plus one successful re-authentication drill and one failover drill.
Machines watch 24×7; a senior engineer responds during Singapore business hours with a four-business-hour target on trading-impacting incidents. Version pinning and tested upgrades, pacing-budget review, monthly reconciliation review, quarterly drills, written monthly report.
Monthly report by the fifth business day with SLO attainment, error budget, incidents, changes and drills.
Execution-integrity library for your strategy host (ib_async, Nautilus or .NET): idempotent order references, order-state machine with duplicate-permId detection, staleness guard, cross-strategy netting, exchange calendars with early closes and MOC cut-offs, kill-switch client.
Chaos suite passes — disconnect, restart, clock skew, competing session — with zero orphaned or duplicated orders.
Daily Flex Web Service pipeline with retry logic and an immutable statement archive; positions, cash and P&L reconciled against the agent’s execution log; administrator-ready extracts; margin early-warning on Excess Liquidity, Cushion and look-ahead values.
Twenty consecutive trading days with zero unexplained breaks.
Move to the connectivity tier your volume justifies: first-party OAuth Web API for headless order management, or FIX once commissions clear IBKR’s monthly minimums — with the gateway kept as a reconciled fallback.
Orders flow on the new path for ten trading days with reconciliation clean.
You keep every credential. Your Security Officer creates the API username and the read-only reporting access; we never ask you to type a password where we can see it.
Account structure, usernames, strategy host, commissions, incidents, allocator timeline. Thirty minutes, no slides.
Day 0Read-only evidence collection, scored report, gap register, connectivity decision, fixed Deploy quote.
Week 1Infrastructure-as-code into your tenant, gateway and agent live on paper then live, drills executed, runbooks and ODD pack handed over.
Weeks 2–5Automated monitoring, business-hours response, pinned upgrades, monthly report, quarterly drills — or take the handover and run it yourself.

Choose the VPS if you need a cheap always-on box and accept that re-authentication, reconciliation and incident response remain your job. Choose the MSP for endpoints, e-mail and compliance archiving. Choose BrokerSRE when the broker session is the single point of failure in a live book and an allocator will ask how you manage it.
Due-diligence questionnaires probe how you track open positions, manage trade data and recover from a failure. BrokerSRE produces that evidence as a by-product of running.
Three things the broker does not provide for you: session choreography (the daily restart and the weekly IB Key re-authentication handled on a schedule, with a human escalation path), state integrity (broker truth reconciled against your order intent on every reconnect and every close, so a stale price or a ghost order is caught in seconds), and evidence (an immutable record you can show an allocator). A bigger server addresses none of them.
No. Your Security Officer creates a dedicated API username for the gateway and, if you want us to see statements, a read-only reporting user or a Flex token — both created and revocable by you inside IBKR’s own user-access facility. Credentials live in your Key Vault and are read by the VM’s managed identity. Our Azure Lighthouse delegation is control-plane only and cannot reach Key Vault secrets.
No service can: IBKR requires two-factor authentication for every user and does not allow opting out. BrokerSRE makes the prompt impossible to miss (voice call, SMS, Teams, e-mail), re-prompts automatically every three minutes until acknowledged, escalates to a second holder, and records the event. Clients above IBKR’s FIX minimums can move to a permanently connected path with the Connect tier.
Below roughly USD 1,500 of monthly commissions, IB Gateway is the economic choice and BrokerSRE makes it reliable. Above that, FIX removes the weekly re-login but needs its own session approval and minimums; first-party OAuth on the Web API gives headless order management at ten requests per second. The Audit makes this decision explicitly, with numbers from your own account.
Anything that speaks the TWS API: Python with ib_async, Nautilus Trader, C#/.NET, Java, and QuantConnect local deployments. The Integrity library ships for Python first, with a .NET port on request.
Azure is the reference implementation because Lighthouse gives the cleanest separation between operating and owning. An AWS variant is available on request for Deploy; the agent, runbooks and reports are cloud-agnostic.
The machines do not sleep: alerts reach your IB Key holders immediately, and the optional kill-switch cancels open orders on conditions you define in writing. The human response window in the Run tier is Singapore business hours with a four-business-hour target; US-session human coverage is available as a scoped add-on.
You do, from day one. Infrastructure-as-code, agent configuration and runbooks live in your GitHub organisation; the deployment lives in your subscription. If we part ways, you revoke the delegation and keep everything running.
No. BrokerSRE is a technology service. It observes, reconciles, alerts and — only if you enable it — cancels open orders. It never originates orders, never holds assets or credentials, and never gives investment advice.
