IB API

IB API Software

Program traders may build their own add-on applications in Excel (using DDE or ActiveX), C++, Posix C++, Java, and Visual Basic for ActiveX with our proprietary IB Application Program Interface (API), which requires connectivity via either the TWS or the IB Gateway. We encourage API users to test their API components with their PaperTrader or the TWS Demo System before actually implementing any new API systems.
