How does Vector connect to Interactive Brokers (IBKR) for futures?

Scope of this article: This article covers IBKR connection for futures trading through NinjaTrader. If you're using IBKR for stocks (via Traders Post), the setup is completely different — see the Stock Trading Broker Setup article for that flow.

IBKR is supported as a futures broker in the Vector setup (see: Supported Brokers). Connecting NinjaTrader to IBKR for futures is structurally different from connecting to Rithmic or Tradovate, which is worth knowing — but the actual setup is handled by the Vector team during onboarding or when you switch brokers.

What's different about IBKR (futures)

Unlike Rithmic and Tradovate, which connect to NinjaTrader directly through a built-in connection, IBKR requires Interactive Brokers' own platform — TWS (Trader Workstation) — to be running on the same machine as NinjaTrader. NinjaTrader talks to TWS through an API, and TWS talks to IBKR's servers.

What this means in practice:

• TWS must stay running for NinjaTrader to receive IBKR data and execute trades.
• If TWS closes, NinjaTrader's IBKR connection drops immediately.
• IBKR has a security feature that auto-logs TWS out periodically (usually nightly or weekly). When this happens, TWS needs to be reopened and logged in before NinjaTrader can resume.

What this means for your daily check

Your normal AM check (see: AM Check Routine) covers the IBKR scenario as well — confirm that TWS is running and that the NinjaTrader Connections indicator shows green for Interactive Brokers. If the connection is dropped, open a ticket at http://support.vectoralgorithmics.io/ rather than reconfiguring TWS yourself — the Vector team will handle the reconnection so the setup stays consistent.

If you prefer to set it up or troubleshoot on your own

The connection setup involves multiple settings (TWS API permissions, socket port matching between TWS and NinjaTrader, auto-logon configuration) that change occasionally with TWS and NinjaTrader updates. If you want to handle the setup yourself, always follow the official NinjaTrader documentation rather than third-party guides — port numbers and specific menu paths in older articles can be out of date, and an incorrect setting can prevent the connection from establishing.

Other brokers and other use cases

• Rithmic, Tradovate, NinjaTrader Brokerage (futures): the IBKR-specific TWS dependency does not apply. See the broker-specific setup articles (Setting Up Rithmic Data Feed, Setting Up Tradovate Data Feed) and the Supported Brokers article for the full list.
• IBKR for stocks: uses Traders Post as the routing layer instead of TWS+NinjaTrader. See the Stock Trading Broker Setup article.
