Can you guide me what data should I subscribe to trade in USA securities using Interactive Brokers (IB)
If you already hold an active account with Interactive Brokers then you can click on ‘Subscribe to Market Data/Research’ which you can find under Account -> Manage Account.
You can see a list of exchanges and instruments for every market in this. Check the market data subscription box only for the instruments and exchange that you wish you to trade on. Please note that you need permission to trade in your selected market.
You can always call the Interactive Brokers Support to get the exact information.
