Browser-based or Stand-alone?
You can run TWS directly from your internet browser, or download the application to your desktop and run it from your PC. If you have a broadband connection, we recommend running the browser-based version of TWS, since this requires minimal maintenance and ensures that you are always running the latest release.
If you use a dial-up connection, we suggest downloading the TWS standalone version and running it from your desktop, as this may result in better performance. To download the standalone version, from the Software menu select Trader Workstation. From the Software tab, select your platform from the Standalone Downloads section.
Note that you must have Internet access in order to receive market data and submit orders, regardless of whether you are running TWS from the browser or from your desktop.

The enhancements
and modifications below are in build 900 of TWS. To identify
the build number, on the TWS Help menu
select About Trader Workstation.
The Accumulate/Distribute algo is designed to allow trading of large blocks of stock without being detected in the market, and can also be set up for high frequency trading. The algo interface provides numerous parameters and conditions to customize your algos. You can now save your strategic algo settings as a reusable template which you can apply at any time to any underlying.
To create an Accumulate/Distribute template, first define the parameters and conditions in the Accumulate/Distribute page. From the Templates menu at the top of the page, select Save Template As and enter a descriptive name. All of the settings you defined are now saved to your new template.The name of the template being used for the order appears in parenthesis in the Accumulate/Distribute tab. To use a template for new orders, highlight a ticker and use the right-click menu to select Trading Tools and then select Accumulate/Distribute. From the Template menu select Load Template and select the desired template name. All parameters from the template are applied to the new underlying.
At this point you can make any necessary modifications for the specific algo order. Save these modifications to this template using the Save Template command on the Template menu. Save the modifications as another, new template using the Save Template As command on the Template menu.
For more information on the benefits of using the the Accumulate/Distribute algo, see the software highlights. For instructions on using the algo in TWS, see the Accumulate/Distribute section of the TWS Users' Guide.
A new static limit price type has been included in the Set limit price to field of Accumulate/Distribute. The new price value, Mark Price, uses the current best price with an optional offset to set a non-dynamic price for the algo.
You can now save bracket orders as part of a basket file, and the orders will retain their parent/child relationship when you trade the basket. To see the relationship between orders, display the Key order management field in the BasketTrader. Note that including bracket orders in a basket will result in the disabling of the Reverse and Cancel and Reverse features.
The Stock Borrow/Loan page now allows you to display data in two different modes. Fee rate is the current, and default, mode. Rebate rate mode displays the rates in italics and uses the opposite sign to the Fee Rate. The difference in the two is simply how you perceive the rate. A positive Fee Rate indicates the borrower pays a fee, and this would show as a negative Rebate Rate, since you are NOT receiving a rebate. On the other hand, a negative Fee Rate would translate into a positive Rebate Rate, indicating that the lender is willing to provide an incentive to the borrower in the form of a rebate. Hard to borrow stocks would be more likely to display a positive Fee Rate and a negative Rebate Rate. Easy to borrow stocks could more likely display a negative Fee Rate and a positive Rebate Rate.
To switch the rate display mode, use the right-click menu in any of the rate field labels (the borrow and lend fields) and choose either Display SBL prices as fee rates or Display SBL prices as Rebate rates.
In addition, a problem calculating the correct shares available for lending in the Stock Borrow/Loan Trader has been fixed.
You can now modify the date, price and volatility for your portfolio, a subset of your portfolio or a specific underlying and the IB Risk Navigator will display the results of your Custom View alongside the current market view of the risk report data. To create a custom view, open a report and on the View menu select Custom Scenario. The left side of the new window shows the Scenario Editor. Modify the date, price and volatility. Filter the affected underlyings by choosing All, Any, a single underlying, or a unique group (using Ctrl + Click). Modify price and volatility by percent change (% Chg), absolute change (Chg) or by an explicit value (ExpV). The projected results to your risk profile are displayed alongside the realtime market scenario in the Custom Scenario table.
For more information on using the IB Risk Navigator, see the TWS Users' Guide.
You can now monitor the potential change in your risk profile directly from an un-transmitted order on the trading window using the Check Risk feature. Create an order and use the right-click menu from the order line to select Check Risk. A P&L plot is displayed showing a line for your current position P&L, and a line that incorporates the risk implications of the un-transmitted order(s) into your current P&L. To see the risk implications of multiple un-transmitted orders, use Ctrl + click to select them, the use the Order menu to select Check Risk. New potential orders for an instrument in which you already hold a position will not be counted as a new position although its implications on your risk profile will be illustrated.
To view a more complete risk profile, open the IB Risk Navigator "What If" function from the Check Risk window by clicking the Open button in the top right corner. The potential positions reflected in Check Risk will automatically be added to your "What If" portfolio.
You can now view realtime ticking news related to any position in your portfolio from the Trader Dashboard. In addition, you can enable a “Recent News” icon for any tickers you have included in the Trader Dashboard. To modify news settings, in Global Configuration, open Information Tools and select Trader Dashboard. Check Show News.
For multi-account users. A new checkbox option, Suppress messages for orders placed by other users, has been added to the General section of Global Configuration. If unchecked, all users will see API order messages regardless of who placed the order. When checked, you will only see order messages relevant to the orders you placed.
In support of the implementation of the OCC Option Symbology Initiative (OSI), which replaces the 5-character OPRA code with a 21 character identifier, TWS has modified the display to allow you to view or hide the local symbol for options. This setting is accessible from Global Configuration in the Display section on the Settings page. Check Show symbol for derivatives to have the local symbol displayed in the ticker line.
For more information on the OSI, visit the OCC Option Symbology page on the IB website.
Customers now have the option to receive delayed market data for exchanges and instruments for which they do not current hold market data subscriptions. The Market Data Request Error window, which displays when the user attempts to add a ticker without having subscribed to market data, now includes two checkboxes at the bottom of the window. Check Subscribe to available delayed market data to use delayed data (if available) for the specific instrument. Additionally check Auto subscribe to available delayed market data to use available delayed data automatically whenever you add a ticker on an exchange for which you do not hold a market data subscription. The trading window highlights tickers that use delayed data in yellow for easy identification.
Charts now include a movable right margin that allows you to move the chart data back toward the center of the chart, but still allows trendlines and studies to continue into the future. To use the margin feature, move your mouse to the far right of the chart parallel to the small arrowheads at the top and bottom of the chart on the right margin. When the margin is movable, the cursor changes to a two-headed blue arrow. Click and slide the margin line to the left. To put the margin back to its original position, right-click the new margin line and select Reset Margin.
A new icon, Show/Hide Volume, allows you to display and remove the Volume subplot along the bottom of the chart with a single click.
Users can now see a chart for the term structure of futures prices. Compare historical and expired prices with the current price, back as far as 2008. To chart the term structure, select a market data futures contract and use the right-click menu to select Charts then select Term Structure.
When using a Line chart in Crosshair mode, a small ball follows the movement of the cursor along the vertical plane of the line chart to help the user see the current price point.
The Account window now includes fields for funds in the Market Value section of the window. New fields include: T-Bills, Bonds, Warrants, Corporate Bonds, Money Market, Mutual Funds and Dividends Receivable.
The following additions and modifications have also been included in TWS build 900:
- A chart problem that resulted in the Relative Strength Indicator (RSI) displaying incorrect values has been fixed.
- An issue with a missing file resulted in many customers needing to restart TWS before they could successfully open their charts. The file has been reinstated and the problem is fixed.
- In some charts, the long-term moving average started in the middle instead of at the beginning of the chart. This has been fixed.
- In instances where no historical market data is available, no error message was being shown in charts with time periods less than one day. This has been fixed.
- Some of the chart studies were not updating correctly to reflect a change to the contract made via the parameters dialog box. This has been fixed.
- In Forex charts only, the ChartTrader order button Buy TRAIL, was not creating the expected trailing stop order line. This has been fixed.
- In ChartTrader, when modifying the original parent order in a bracket by clicking and dragging the order line onto the chart, the child orders followed
accordingly and both the parent order and child stop order transmitted automatically as expected at the new price, but the target limit order did not automatically transmit at the
new price.
- In the OptionTrader, the Order Reference value set in the options Preset did not come through as expected when creating orders; instead the Order Reference value "OptTrader" was always used. This has been fixed.
- When submitting a bracket order routed to IDEAL, the relationship between the parent and child orders was not retained as expected. This has been fixed.
- Advisors: The delta basket hedge feature in the IB Risk NavigatorSM for Advisors was not using the selected account. This has been fixed.
- Advisors: The Algo tab on the order ticket would not appear as expected when CSFBALGO or JEFFALGO was selected as the destination. This has been fixed.
- Advisors API: When sending orders that allocate through a user-defined Allocation profile, the average price was not being calculated. This has been fixed.
- The Export Page to Excel command on the File menu has been renamed to Export Page in Legacy Excel Format and is disabled by default for new and upgrading users. Please use the Export Contracts command from the File menu to export to Excel.
- Parent-child orders such as brackets being sent through the APIs were not being handled and executed properly in some circumstances. This has been fixed.
- In the BookTrader, some price levels were being left blank due to an issue with the deep data instructions. This has been fixed.
- The Order Preset for VWAP algos was incorrectly saving a specific date, which made VWAP orders submitted on subsequent days invalid. The date piece of the time/date settings for Algos has been removed to fix this issue.
- The Presets feature settings were not being restored with other settings when you used the Restore Settings command on the File menu. This has been fixed.
- A problem with the Single combo tab in the Combination Selection box would not allow straddle and vertical spread strategies to be constructed for certain contracts. This has been fixed.
- API: If a user sent an order with an invalid negative stop price via the API, TWS would accept the non-conforming order and incorrectly assign the minimum allowed market price to the order. This has been fixed so that TWS will reject the order and user will receive an error message.
- When using the Update Orders box to modify algo orders, sometimes the algo destination feature would incorrectly revert to No Change and not allow changes to the price or other algo parameters. This has been fixed.
- Volatility orders: When modifying Volatility orders via the Order Ticket, the Basic tab shows the Limit price and the Volatility tab shows the price in Volatility terms. Both fields were editable but not in sync, so there was no way of knowing which price the customer wanted to use if the price was changed via the Order Ticket. To avoid confusion, the Limit price field on the Order Ticket has been disabled for Volatility orders. In other order entry venues including the trading window and the Order Wizard, volatility orders have only a single price field, which is still enabled.
- Blotter: Users can now enter Away trade destinations on pages other than the Blotter. To add an Away destination, in the Destination dropdown list click Away. Enter a name for a new destination and click OK.
- Blotter: Changes to the commission rate in the ticket area would only last for the current session and would revert back to the original commission the next time the user logged in. This has been fixed.
- Blotter: There was a problem creating a ticket for a STK/OPT combo with the stock leg marked as sell short. This has been fixed.
- Combo orders: When selecting the strike price while defining a combo order, if you used the keypad or arrow keys the strike price did not accurately reflect your choice. This problem has been fixed.
- Combo orders: In the Single combo tab of the Combination Selection box, users were unable to modify the ratio in a combo after the second strike price was selected. This has been fixed to allow changes to the ratio both before and after the strikes have been selected.
