Release date: 5/31/21

See the 8.2.0 to 8.3.0 upgrade notes for information about upgrading to this version.

Deprecated functions

New features

  • Market depth zoom control — The new zoom control for market depth allows users to better see the limit order book close to the last execution price. This helps users hide orders that are significantly off-market and thereby distort the view of the market.

  • Cross section — Cross section charts enable the visualization of a matrix of data from a moment in time (including real time). A cross section is like a slice of a time series chart, revealing the data contained in the slice. Cross section charts visualize data of all kinds, not just financial information such as stock quotes.

    Note: The Term Structure plug-in has been replaced by a new Cross Section plug-in that provides all of the capabilities of Term Structure and much more. As a result, the Term Structure classes and methods have been renamed as Cross Section classes and methods. See the 8.2.0 to 8.3.0 upgrade notes for the complete list.

  • Term structure timeline date selector — Term structure charts now include a range finder that plots a mountain chart of yield or price spreads over time. Spreads are the difference in yield or price of debt instruments of varying maturities; for example, the difference in yield between the 10YR and 5YR bonds. Spreads are selectable from the Timeline Date Selector's drop-down menus. Slider controls enable selection of dates along the Timeline Date Selector's x-axis for the main curve and historical curves.

    Note: Term structures are now a use case of ChartIQ's new cross section charting capabilities. As a result, many of the classes and functions that apply to term structures are part of the cross section API. See the 8.2.0 to 8.3.0 upgrade notes for more information.
