Application Programming Interfaces
IB offers several alternatives for connecting directly to our trading system, including:
- A proprietary Application Program Interface (API) which operates through the Trader Workstation and does not require additional technical overhead such as a dedicated FIX server.
- An industry standard FIX solution for customers who can support a FIX Computer-to-Computer Interface (CTCI) infrastructure.
Our APIs are available for DDE for Excel, Java, C++, and ActiveX. For traders with little or no programming experience, we recommend the DDE for Excel platform, as Excel offers a familiar and user-friendly interface and the DDE API is seamlessly integrated into the Excel application. To help you get started with the TWS APIs, we invite you to attend our live API for Beginners webinar.
Our CTCI connection supports FIX versions 4.1 and 4.2, with support for selected 4.3, 4.4 and custom IB tags. See the CTCI FIX tab for more information.
Both solutions can connect through the internet, extranet, or a dedicated line. Click the Interface Comparison and Connection Comparision links above for more details.
Program traders may build their own add-on applications in Excel, C++, Java, and Visual Basic with our proprietary Application Program Interface (API), which requires TWS to be running in the background. We encourage API users to test API components with the TWS Demo System before actually implementing any new API systems.

The IBGateway client allows for FIX CTCI connections to IB over the Internet. It is a piece of software that acts as a bridge between your FIX engine and IB. The software can also be used in place of TWS to deliver market data, using the same protocols as the Trader Workstation APIs. In this scenario, you do not need to have TWS running to get API market data. IBGateway Software and the Users' Guide can be found by clicking the buttons at the bottom of the page. To find the Request Market Data API method click here.
Individuals and Non-Pro advisors that require CTCI integration should send a request to tac@interactivebrokers.com. Professional Advisors, Funds, Trading Groups, and Brokers requiring integration should contact their sales representative. Integration can take up to a week.
Once integration has been completed, please follow the steps in order to load the IB Gateway Software that will allow you to receive market data through our API in conjunction with your CTCI order management connection.

Click on a build number or topic in the table to access the associated Release Notes. Notes for the most recent build are listed first.
The modifications below are in build 9.63 of the TWS API. Please note that all the enhancements for release 9.63 require the minimum server version 45 (TWS version 896).
For clarification on any of the items listed, refer to the appropriate section in the API Reference Guide, or send us an email at Beta Support.
When trading is halted for a contract, TWS receives a special tick: haltedLast=1. When trading is resumed, TWS receives haltedLast=0. A new tick type, HALTED, tick ID = 49, is now available in regular market data via the API to indicate this halted state.
Possible values for this new tick type are:
- 0 = Not halted
- 1 = Halted.
This enhancement applies to the ActiveX, C++ and Java APIs.
The following fields have been added to the Contract structure:
String secIdType; // CUSIP;SEDOL;ISIN;RIC
String secId;
Use these fields when querying contract details (reqContractDetails) or when placing orders (placeOrder).
secIdType supports the following identifiers:
- ISIN - The International Securities Identification Number (ISIN) that uniquely identifies the security but not the location at which it is traded. Example: Apple: US0378331005.
- CUSIP - The nine-character Committee on Uniform Securities Identification Procedure (CUSIP) identifier for North American securities. Example: Apple: 037833100.
- SEDOL - The Stock Exchange Daily Official List (SEDOL) identifier consisting of 6-AN + check digit. Example: BAE: 0263494.
- RIC - The Reuters instrument code, consisting of the RIC Root (exchange-independent) and a suffix identifying the exchange at which the contract trades. RIC Root is unique for each company. Example: AAPL.O for Apple on NASDAQ.
Notes: If the CUSIP is defined, then ISIP = [US/CA][CUSIP][check digit]. The ISIN and CUSIP can replace the underlying, but when a contract trades in several locations (regions), you must also provide the primary exchange.
This enhancement applies to the ActiveX, C++ and Java APIs.
The following fields have been added to the Contract Details object:
- String contractMonth
- String industry
- String category
- String subcategory
- String timeZoneId
- String tradingHours
- String liquidHours
Examples:
contractMonth=200906
industry=Financial
category=Investment Svc
subcategory=Brokerage
timeZonId=EST
tradingHours=20090507:0700-1830,1830-2330;20090508:CLOSED
liquidHours=20090507:0930-1600;20090508:CLOSED
This enhancement applies to the ActiveX, C++ and Java APIs.
- Fixed a typographical error in Util.FindOrderID.
- Fixed the blinking on the Tickers page.
- The localSymbol column has been added to all relevant pages.
- Partial fills are now processed correctly.
- Fixed TWS crashes that were due to a memory leak in a dde.dll.
