The first time you log in to TWS, you’ll need to take a little time to populate your screens with data, understand the different allocation methods you can use, and finally practice creating orders.
We strongly recommend that you open a paper trading account as described in Opening a Paper Trading Account to familiarize yourself with Trader Workstation’s many features without accidentally submitting a trade.
You can run TWS directly from your Internet browser (recommended), or download the software to your PC and launch it directly from your desktop as a standalone application. For more information, see the Trader Workstation page on the IBKR web site.
