TWS Release Notes

The enhancements and modifications below are in build 905 of TWS. To identify the build number, on the TWS Help menu select About Trader Workstation.

Subscription-based Wall Street Horizon Events Calendars

Customers can now subscribe to the Wall Street Horizon Events Calendar. This feature includes access from both the Analytics menu and the Company Fundamentals tool, and provides the following:

To subscribe to Wall Street Horizon, log into Account Management, and from the Trading Access menu select Market Data Subscriptions. Check the appropriate box and continue through to accept the change. Updates in your market data subscriptions may take up to one business day to be applied.

For more information, see the TWS Users' Guide.

Yield Optimizer Trading Tool

A new trading tool, the Yield Optimizer, has been added to the Trading menu. The Yield Optimizer allows you to compare the borrow rates for hard-to-borrow stocks using different strategies, including EFPs, borrowing via AQS using the SBL instrument type, or having IB borrow shares for you. To borrow shares using one of the Yield Optimizer methods, select the ticker line in the Borrow Shares panel. A symbol-specific panel opens, with a single data line for each available borrow strategy.

For information on the Yield Optimizer, see the TWS Users' Guide.

Route Options for Highest Rebate

A new Options Strategy selection box allows users to have non-marketable Smart-routed options orders routed to the exchange offering the highest rebate. To set this directive, from the Configure menu select Global Configuration. Choose Smart Routing in the left pane, and use the Options Strategy drop-down box at the bottom of the page to choose "Highest Rebate."

Accumulate/Distribute: Large Order Limit Price and Combo Time Zone

The Accumulate/Distribute tool now includes a limit price field for use with the Take entire offer feature. Use this field to set the price condition if you elect to take all quantity offered at the size you define. In addition, to support combination orders that have legs on different exchanges in different time zones, a time zone field has been added to the Accumulate/Distribute algo. If you elect to set a start time, you can choose the time zone you want to use.

For help using Accumulate/Distribute, see the TWS Users' Guide.

Percentage Change Price Condition for Alerts

A new condition type, Percentage Change, has been added to the list of conditions for both Conditional Orders and Alerts.
This selection joins existing conditions Price, Margin Cushion, Trade, Time and Volume. Use this condition to create an alert that will trigger if the percent of price change for a specified ticker is less than or equal to, or greater than or equal to, the specified percentage change. For example, you could create an alert that would trigger if the price of IBM moved up or down by more than 3%.

Combo Selection Redesign

The functionality for creating combo orders has been enhanced to be more intuitive and easier to use.

ScaleTrader Order Tabs

The ScaleTrader now includes three new tabs - Simple, Pair and Combo. Use the default Simple tab to create a single order. Use the Pair tab to create a two-legged pair trade. Use the Combo tab to create a combination order. Please note that IB can only guarantee US Smart routed option-option and stock-options combos. If you open the ScaleTrader from a blank line, select a tab and then define your ticker. If you open ScaleTrader after selecting a ticker, it opens as a Simple order by default. If you elect to change the order to a Pair or Combo order, use the "Edit" button on the far right side of the tab set to re-define your order.

For help using the ScaleTrader, see the TWS Users' Guide.

Market Scanners Available on Weekends and After Hours

You can now use TWS Market Scanners (with the exception of bond and EFP scanners) after trading has stopped on evenings and weekends. After-hour scanners use data from the previous close to provide a static snapshot as of the market's close. Data provided in the after-hours Market Scanners includes the last bid, ask, and change. Snapshot data is identified by a gray background color in the Scanner display.

For more information on using Market Scanners, see the TWS Users' Guide.

API: Option Analytics Fields

API users will now receive options analytics data, including gamma, vega and theta (delta is already available) via the tickOptionComputation() method when requesting market data on an option.

API: Improved Message Reporting Log

The API message log, which is sent to the IB development team for evaluation of problems, has been enhanced to improve the quality of tracking data included. Two new optional checkboxes have been added to the API configuration page in TWS: Create raw API log and Include market data in API. Both of these selections help to improve the content of the message log.


Recent changes to our real-time charts include:

Average Price Decimal Display

For products that require a custom market rule (ZF, ZN, ZB etc), the Average Price in TWS will ignore user display settings for rounding and decimal places, and display using the market rule.

Special Dividends

The Yield calculations will now include any special dividends, such as one-time payments.
