Version 8.0.0

Release date: 8/5/20

BREAKING CHANGES

  • All version 7.5.0 charting templates must be updated to work with the new ES6 modules. Please see the 7.5.0 to 8.0.0 upgrade notes.
  • A file:/// URI can no longer be used to load the sample template files or any other HTML file that imports library modules. The library's ES6 modules must be loaded using HTTP or HTTPS to prevent CORS (cross-origin resource sharing) errors. ES6 requires special HTTP headers that provide enhanced security for cross-origin requests. As a result, double‑clicking or double‑tapping library HTML files to load them no longer works.
  • The CIQ.UI.Chart#initStorage function has been removed from the library.
  • The CIQ.UI.Layout#getOutliers function is no longer public.

New features

  • ES6 modules — The library now consists entirely of ES6 modules, enabling you to create custom module bundles. Sample webpack templates (in the library root folder) demonstrate how to tree shake the library and remove any unneeded dependencies.

    See the 7.5.0 to 8.0.0 upgrade notes for more information.

    • New CIQ.activateImports function is called to activate imports for use by the API. If an import is not activated, its code is inaccessible and may be tree shaken by bundlers. The function keeps track of which imports have been activated already so no import gets added more than once.

  • Projected volume studies

    Projected Volume at Time — Projected Volume at Time (PVAT) is an average of intraday trading volume for a given time segment. The study enables traders to evaluate during the trading day whether today's volume is above or below average and see projected volume for the remainder of the day. A bar graph shows the volume at each periodicity interval (candle); an overlay line shows the average volume for each time segment. When the current volume exceeds the PVAT average by a customizable percentage, the color of the volume bar in the bar graph changes to a customizable color, alerting the user.

    Projected Aggregate Volume — Projected Aggregate Volume (PAV) is an aggregation of the day's trading volume up to the current time along with a projection of the aggregate volume for the remainder of the trading day. The study reveals whether the trend in trading volume is above or below average and provides a forecast of volume for the rest of the day.

  • Enhanced Life Cycle Events

    Event zoom — Enables users to double click to zoom in from a broad periodicity to a finer level of detail to see more granular data, then zoom back out.

    Optimized panel height — The panel now adjusts for the number of swim lanes displayed.

    Event details from the swim lane — Hovering the mouse over a single event or duration event displays a tooltip containing the event headline. Selecting an event marker shows the event headline and story in a pop-up display.

    Easier customization

    • The constants.js file in the plugins/timespanevent folder now contains all configurable constants.

    • The timespanevent.js file in the plugins/timespanevent folder is no longer obfuscated. The file contains customizable functionality for displaying life cycle events.

  • Term Structure

    Term structure charts can now display curves for multiple entities when the entities don't share the same set of instruments. For example, the U.S. Treasury yield curve contains maturities (instruments) of 1, 2, 3, and 6 months, but the yield curve of other sovereign bonds may not contain these short-term maturities. Term Structure lets you compare the curves just the same (if the entities have at least one instrument in common).

    • New CIQ.TermStructure.sortInstruments function sorts term structure instruments by their names.

  • Hidden outliers

    In study panels — Outliers can now be hidden in study panels. When a chart has outliers, studies associated with the chart may have outliers too. Now, study outliers can be hidden, replaced by markers that indicate the outlier location and value, making the study data trend clear. The markers can be selected to reveal the outliers. Controls at the top and bottom of the study's y-axis also show and hide the outliers.

    On multiple y-axes — Hidden outliers are supported on multiple y-axes; for example, when a comparison series has been added to a chart. The outliers for each series can be shown and hidden independently using the outlier controls on the respective y-axis.

  • Preferences menu

    Preferences menu In the technical-analysis-chart.html and sample-template-advanced.html templates, the CHART PREFERENCES, Y-AXIS PREFERENCES, THEMES, and LOCALE sections of the Display menu have been moved to a new preferences menu, which is opened and closed by a cog wheel control .

    See the following markup in the templates:

    <cq-menu class="ciq-menu ciq-preferences collapse">
    <span></span>
    <cq-menu-dropdown>
    .
    .
    .

    On mobile devices, the cog wheel on the left toolbar has been changed to a vertical ellipsis.

    The Display menu is now limited to showing chart types.

  • Angular

    The Angular component toolkit provides developers with a variety of complete charting solutions that can be easily incorporated into Angular applications. The charting application components are the equivalent of some of ChartIQ's most popular sample templates. New additions include:

    • MultiChartComponent — Displays two advanced charts on screen simultaneously like sample-template-multi-charts.html.
    • ActiveTraderComponent — Creates an information-rich desktop for cryptocurrency traders and other active traders; equivalent to active-trader-chart.html.
    • CustomChartComponent — Integrates native Angular components with ChartIQ W3C-standard web components; technical-analysis-chart.html plus Angular.

    The Angular seed project has been updated with the ES6 modularization changes.

  • React

    The React app and seed projects have been updated with the ES6 modularization changes.

UI enhancements

  • CIQ.ChartEngine.preferences.whitespace — The whitespace between the most recent data point (candle) and the right side of the chart is now preserved as new data points are created. In the previous version of the library, the chart removed the whitespace when new candles appeared. See the Range and Span tutorial for more information.

  • New CIQ.ChartEngine#doubleClick handles all double-clicks on the chart container. Applies a double-click event to a CIQ.Marker and dispatches the doubleClick event, which invokes the doubleClickEventListener.

  • New doubleClickEventListener callback function is called by CIQ.ChartEngine#doubleClick when the chart is quickly clicked or tapped twice.

  • New CIQ.ChartEngine#doubleClickTime property sets the maximum number of milliseconds between clicks that trigger a double-click.

  • New CIQ.Marker#doubleClick function called when a marker node is double-clicked. Override this function with your own implementation to prevent CIQ.ChartEngine#doubleClick from dispatching the doubleClick event and invoking the doubleClickEventListener.

  • CIQ.ChartEngine.AdvancedInjectable#touchDoubleClick function no longer deletes overlays, series, or drawings or returns the chart to home when the user taps an axis.

  • CIQ.Marker.Performance constructor added the following parameters to better position and display markers: params.infoOnLeft, params.infoOffset, and params.invert.

  • CIQ.Marker.Performance#calculateYPosition function added the params.inverted parameter to enable proper calculation of the vertical position of markers when the marker stem is inverted.

Chart engine enhancements

Data management enhancements

  • The newChartEventListener callback function has added the upToDate parameter, which is true if quotefeed~dataCallback reports that no more future data is available.

  • The quotefeed~dataCallback callback function has added the upToDate parameter, which you should set to true to stop forward pagination requests if you know that no newer data is available.

Notification enhancements

Panel enhancements

Studies enhancements

Web component enhancements

  • New CIQ.UI.components function gets an array of components from the list of registered components. The array elements contain the tag, name, registration status, and markup of the matched components.

  • New CIQ.UI.markupDependencies function returns the dependencies of all web components based on the component markup.

Plug-ins enhancements

  • The following folders in the plugins folder have been renamed:

    Old name New name
    tradingcentral analystviews
    recognia technicalinsights
    cryptoiq activetrader

  • New CIQ.ChartEngine.pluginBasePath property sets the default base path for plug-ins.

  • New CIQ.VisualEarnings constructor function adds an instance of the Visual Earnings plug-in to the chart and creates the Visual Earnings drop-down menu.

  • New CIQ.UI.VisualEarnings helper function is available for managing the Visual Earnings plug-in.

Range slider enhancements
