Access market/portfolio data and submit trade orders in Matlab via Interactive-Brokers (IB), using the IB-Matlab application. IB-Matlab free trial

IB-Matlab is a Matlab connector to InteractiveBrokers, enabling users to leverage Matlab’s superior analysis and visualization capabilities, with IB’s low-cost data-feed and brokerage trading platform. IB-Matlab can be used for both automated algo-trading and selective manual trading, as well as continuous market data feed.

IB-Matlab provides a reliable, easy-to-use Matlab interface to Interactive Brokers that works right out-of-the-box on all Matlab platforms (Win32, Win64, Mac, Linux) using simple Matlab commands:

IB-Matlab connectivity (Matlab and TWS may be on separate computers)

  • query current market data (quotes and market depth) in snapshot or streaming modes.
  • fetch historical, intraday and live market data, using IB as a data-feed provider.
  • lookup fundamental data, contract trading info and option chains on assets.
  • place scanners that filter the market for securities that match certain criteria.
  • retrieve the current portfolio contents, balance, P&L, margin, and other IB account values.
  • place trade orders for multiple security types and trading parameters on dozens of exchanges worldwide.
  • monitor open trade orders and track executions (partial/full).
  • attach user-defined Matlab callback functions to ~40 data events sent by IB (trade executions, real-time tick data etc.)
  • combine all of the above for a full-fledged end-to-end automated trading system using plain Matlab.

IB-Matlab was developed by a renowned Matlab expert, Yair Altman, and is continuously maintained and improved since 2010. The product is actively used by hundreds of financial institutions and individual traders/quants worldwide.

IB-Matlab was optimized for excellent performance, reliability, stability, compatibility, feature set and overall value. A very detailed User Guide is available, complete with multiple working usage examples and implementation tips.

  • Full solution – IB-Matlab is an inexpensive application that enables simple Matlab access to IB’s API functionality.
  • Tried and tested – IB-Matlab has been installed, tested and in active use by thousands of traders and quants since 2010. IB-Matlab is reportedly used to actively trade $100 million daily. It is rock solid.
  • Inexpensive – IB-Matlab provides excellent value compared to other connectors of its kind or to the amount of time that would be needed to develop a similar robust connector from scratch. A fully-functional free trial version is available (see below).
  • Easy to use – Users can activate IB’s API by simple Matlab commands, without any need to know Java (on which the API is based) nor Matlab programming. IB-Matlab simplifies the IB API in a very easy-to-use yet powerful interface that can be used by any Matlab user, novice or advanced.
  • Connectivity – IB-Matlab enables users to connect Matlab to TWS or the IB Gateway, on the Matlab’s computer or on a different computer.
  • API functionality
    • Active trading actions: buy, sell, short, close, modify, cancel, exercise, lapse
    • Numerous settable contract and order attributes
    • Market query actions: current market data, scanner filter, streaming quotes, real-time bars, snapshot and streaming market depth, historic and intraday data, contract details, options-chains
    • Account query actions: account info, portfolio list, open orders, executions data
    • IB events: all ~40 asynchronous events that are sent by the IB server are accessible in Matlab (see below)
  • Novice and advanced users – Users can use either simple one-line Matlab commands, or internal objects exposed by IB-Matlab, to access the full range of IB’s API.
  • Multiple (FA) accounts – Financial advisors can easily manage multiple IB accounts from a single Matlab session/script, including portfolio queries (parent and sub-accounts), routing trade orders to FA profiles/groups and allocation methods/percentages.
  • Remote access – IB-Matlab can be installed on the same platform as TWS, or on a separate machine that connects to the IB client remotely.
  • Event callbacks – Users can easily attach Matlab code (callbacks) to IB events. For example, this enables adding an entry in an Excel file, or sending an email/SMS (text message), whenever a trade order executes, or a specified price is reached.Mathworks partner
  • Additional functionality – IB-Matlab also provides functionality that is not readily available in the basic IB API: the ability to specify automated trading; specifying custom trades such as brackets or combo spreads; automatically changing unfulfilled limits based on the momentary bid/ask prices; and changing order types at a certain time.
  • Compatibility
    • Platforms: IB-Matlab works on all platforms on which Matlab runs: Windows (both 32 and 64 bits), Mac, Linux/Unix.
    • Matlab: IB-Matlab works on all Matlab releases since 2006, including the latest release (R2023a).
    • IB clients: IB-Matlab works with both Trading WorkStation (TWS) and IB Gateway since 2009, including version 983.
  • Security – IB-Matlab does not transmit any information externally except to IB, so your portfolio and trading information are as safe as your own computer.
  • Performance – IB-Matlab is optimized for performance, providing fast and responsive connectivity. While Matlab as a platform is not well-suited for HFT, IB-Matlab still enables placing multiple requests per second, and receiving dozens of streaming quotes or other IB messages per second.
  • Development – IB-Matlab was developed by an acknowledged Matlab expert, who wrote the reference textbooks on Matlab-Java interfacing and Matlab performance.
  • Support – Custom development and ongoing support is available directly from the developer, with extremely fast response times.
  • Documentation – Extensive and comprehensive documentation, with numerous code examples and usage tips (see below).
  • Client base – IB-Matlab is actively used by many hundreds of traders worldwide, ranging from individual traders, to hedge funds and banks.
  • Backtesting – IB-Matlab does not include backtesting functionality. IB-Matlab’s author (Yair Altman) has extensive experience in developing complete backtesting and real-time trading applications. Yair will be happy to either develop a new application based on your specifications, or to integrate IB-Matlab into an existing application, under a consulting contract.

No other solution provides this rich set of features – not even close (see comparison).

While IB’s Java connector, which is provided by IB, can be used directly in Matlab, setting up the event callbacks and data conversions between Matlab and the connector is definitely not easy. You need to be familiar with both Matlab AND Java, at least to some degree.

Other applications that solve these problems are either expensive, not supported, or limited in functionality or deployment. For example, ActiveX solutions only work properly on 32-bit Windows and even then lose some events and are relatively slow. matlab2ib quant2ib

AutomatedTrader magazine

So, do we like it? Well, IB-MATLAB is robust, very easy to learn how to use and does exactly what it claims to do – namely provide a simple and efficient order interface between MATLAB and Interactive Brokers’ API. It also costs peanuts…
So yes, we like it – a lot.

– Andy Webb, Automated Trader magazine, Q3 2011 (“The Virtue of Simplicity” article online; or downloadable PDF)

…At that point I turned to Yair Altman’s IB-Matlab product. Happily, this uses IB’s Java api, which is a great deal more robust than the ActiveX platform. It’s been some time since I last used IB-Matlab and was pleased to see that Yair has been very busy over the intervening period, building the capabilities of the system and providing very comprehensive documentation for it. With Yair’s help, it took me no time at all to get up and running and within a day or two the system was executing orders flawlessly in IB’s TWS. …
Yair is very generous with his time in providing support to his users and his responses to my questions were fast and detailed.

– Jonathan Kinlay, Quantitative Research and Trading, March 5, 2015 (“Algorithmic trading” article)

Easy integration with IB through IB-Matlab… The Trading Toolbox isn’t very robust, it’s really buggy, … I would love to get the Trading Toolbox up and running, but I think that Yair has got it covered for Interactive Brokers, I just use his program…
IB-Matlab is our wrapper for the IB API, so that we don’t have to write our own Java connector. IB-Matlab is a robust Java connector, complete wrapper for the IB API. A cheap investment, it’s definitely worth it. I can’t even stress enough how much time it will save you. Don’t build from scratch, it is cheaper and faster to buy from 3rd-party vendors. If I was to build IB-Matlab it would take me several weeks and for only $400 I could have a turnkey solution, I mean it’s a no-brainer there… It’s better than those retail trading platforms. This is the cheapest professional-grade system that you can get. IB connected to IB-Matlab connected to Matlab connected to the Data-Feed Toolbox connected to IQFeed is the cheapest technology stack that will give you trading robustness.
Yair is extremely helpful, provides great customer support.

– Chris Reeves, A2X Capital, Feb 27, 2015 (“Algorithmic Trading System” video)

Also quoted: IB-Matlab is the most robust wrapper for the IB API I have come across. Amazing value for the price!

  1. Each individual license (Commercial, Academic, or Bundle) is limited to a single user on a single physical computer. Running on multiple computers requires multiple individual licenses, or one of the other license types (Site, Deployment or Development).
  2. The Academic license is available to currently-active members of a degree-granting academic institution (students or faculty) who use an academic email account.
  3. The IB-Matlab+IQML Bundle is available with both IQML Standard and IQML Professional. See IQML’s webpage for details and pricing.
  4. Consulting/support package is available, please contact for details.
  5. IB-Matlab can be compiled and deployed using the Matlab Compiler. Each computer running a compiled IB-Matlab requires an IB-Matlab license (just like a non-compiled IB-Matlab that runs in Matlab), unless you get a group license (Site, Deployment, or Development). In other words, for your deployed computers you have a choice of either buying individual licenses (separately for each deployed computer), or a group license which does not require dedicated license activations.
  6. With each license purchase, you will receive the latest version of the product available at that time.
    License renewal can be to any license type and any duration, not necessarily the same as the original license purchase, as per the pricing table at the time of renewal.
