Over the past months we have continued to enhance the TWS and API trading platforms. The major changes are noted below.

TWS

    * Option Portfolio now has time slicing parameters which allow you to randomize the increment size and time intervals. (Release 893)
    * Option Portfolio adds a user-defined Reference Portfolio area. The query returns a simulated portfolio that matches or betters the P&L of your reference portfolio. (Release 895)
    * ScaleTrader now includes a chart, a summary area, and Top Price and Bottom Price fields for added control. (Release 895)
    * Advisors can now use the Percent Change Allocation for combination orders. (Release 893)
    * Deep Book data allowances have been changed to coincide with market data allocation, which is determined monthly based on commissions. Based on market data, the Deep Book data allows a minimum of three and maximum of 30 simultaneous deep books.
      (Release 894)
    * IB Risk Navigator now includes the ability to view portfolio relative P&L by expiry, using the Expiry Slicer. (Release 894)
    * OptionTrader now provides a button to auto-load chains for all option positions you hold in the underlying. (Release 895)
    * Redesigned Conditional Order builder allows you to drag and drop conditions into the builder, and translates conditions into readable text. (Release 895)
    * Default values are now included in the Precautionary Size and Price Limit fields on the order Presets. (Release 894)
    * Two new order types have been added, Trailing Limit if Touched and Trailing Market if Touched. These work similar to trailing stops, but put the offset on the opposite side of the market from a stop. (Release 895)
    * Non-guaranteed combination orders supported for some non-US products. (Release 896)
    * US Smart stock historical data for 1-day charts now goes back to 1995.
    * Ability to offset N225 futures trades between GLOBEX and SGX.
    * Post Only order attribute for directed Island and BEX limit orders lets you instruct TWS to never take liquidity.
      (Release 895)
    * Additional destinations added to European Smart Routing to improve fills.
    * Subscription-based support for ISE option depth of book data.
    * Ability to bypass IB auto-capping of market and stop orders for prices that seem out of range by checking the Bypass Market Cap checkbox in Misc tab on the Order Ticket. (Release 895)
