Use IB's proprietary or 3rd party terminals to trade your Interactive Brokers account with Darwinex.
To access your Interactive Brokers account, it's required that you either launch the Client Portal download IB's proprietary terminal (TWS), or download the IBKR Mobile app, and log in to your account.
The TWS Application Program Interface (API) accommodates connection to a variety of third-party vendors (e.g. TradingView, Multi Charts, Ninja Trader) who offer complementary order entry, charting, back-testing, and analytics software programs designed to expand the functionality of TWS.
For details about how to connect to the TWS API, please consult the relevant 3rd party tools' user guides.
Note that to use 3rd party tools with your IB account, you have to be logged in all the time to IB's proprietary platforms.
