Version 28.3.0​

Date: Thu Oct 24 2024

New Features

Bug Fixes

  • Anchored Note in multi-layout. Fixed an issue where plotting a saved Anchored Note in multi-layout would raise an error.
    Trading Platform Only
  • Fixed symbol logo persistence in legend. Resolved an issue where a failed image load (e.g., a 404 error) for a symbol logo would cause the previous logo to persist in the legend. Now, the legend correctly updates to reflect the absence of a logo when loading fails. See the Symbol logos section of the Legend documentation for more details on the feature.
  • Fixed ordering of symbol logos. Fixed an issue where symbol logos with two URLs defined in logo_urls were displayed in an inconsistent order. The order has been corrected on the chart legend and within the Account Manager table.

Date: Tue Oct 01 2024

New Features

  • Added Rank Correlation Index indicator.
  • Support building seconds bars from ticks. Trading Platform now supports building seconds bars from ticks for symbols configured to support it. Compatible symbols must set the build_seconds_from_ticks flag to true. Additionally, has_seconds and has_ticks must be true, and seconds_multipliers must be an empty array or only contain multipliers that the datafeed provides itself.
    Trading Platform Only

Improvements

  • Added an option to customize the default Volume MA calculation in the Volume indicator. By default, the Volume MA, optionally plotted in the Volume indicator, used the SMA calculation. We have now introduced two additional options: EMA and WMA.
  • Added new event to SubscribeEventsMap. The timeframe_interval event is triggered when the one of the bottom left intervals is selected or the setTimeFrame API is used.
  • Added a symbol change to MACD indicator. It is now possible to change the targeted symbol when plotting MACD indicator without using the main series.

Version 28.1.0​

Date: Wed Sep 04 2024

Breaking Changes

New Features

  • Added iframe_loading_same_origin featureset. The iframe_loading_same_origin featureset ensures the library's iframe is loaded from the same domain as the library_path files.

Improvements

  • Added new event to SubscribeEventsMap. The study_dialog_save_defaults event is triggered when the Save as default option is selected in the indicator settings.
  • Changed the return type for OrderPreviewResult. When implementing previewOrder, you can specify links to external URLs now. The links will be displayed within the warnings or errors block.
    Trading Platform Only
  • Added an item counter for custom pages. By default, custom pages added to the Account Manager do not display the number of items in their corresponding table. Enabling displayCounterInTab will show this number next to the tab title.
    Trading Platform Only

Bug Fixes

  • charting_library_debug_mode. Fixed an issue where enabling the featureset charting_library_debug_mode was of no effect.
  • Instant display of refreshed marks. Fixed an issue where new marks added after calling refreshMarks were not immediately displayed on the chart. Previously, these marks only appeared after user interaction, but now they are instantly visible once the data is provided.
  • Fixed an issue with multiple_watchlists featureset. When the multiple_watchlists featureset was disabled, it was still possible to see the Create a new list option under the Watchlist drop-down menu.

Documentation

  • New how-to guide. Check out a new guide on enabling debug modes to help identify potential issues when implementing your app and ensure it is running smoothly.

Version 28.0.0​

Date: Wed Aug 14 2024

Breaking Changes

  • Removed full_name. The LibrarySymbolInfo.full_name property was removed from public API. The property contained strings in the 'EXCHANGE:SYMBOL' format and was used to request data from the datafeed. Therefore:

    • Now, you should use either the name or ticker property to specify an identifier for a certain symbol. For more information, refer to the Symbology article.
    • Instead of 'EXCHANGE:SYMBOL', the library will send either name or ticker values to the datafeed when calling methods such as getBars, getQuotes, and subscribeQuotes.
    • The 'EXCHANGE:SYMBOL' strings are no longer displayed in the Trading Platform UI. The symbol name will be used instead. You can disable the prefer_symbol_name_over_fullname featureset to revert to the old behavior.
      Trading Platform Only

  • Deprecated API methods. The following methods are now marked deprecated for the Advanced Charts users.

    These methods will be removed from the Advanced Charts library in the next major version. However, they will still be available in Trading Platform.

  • Make cancelOrders optional. The cancelOrders method is marked as optional because the library calls it only for the Depth of Market widget.

    Trading Platform Only

  • Removed the calculatePLUsingLast flag. The calculatePLUsingLast broker configuration flag has been removed.

    Trading Platform Only

  • Symbol search dialog behavior. Previously, when users pressed Enter in the Symbol Search dialog, they could enter arbitrary input directly. This input was passed to the datafeed for resolution and loading, regardless of whether the input matched any search results.
    Now, pressing Enter selects the top search result unless the user has explicitly chosen another item. If there are no search results, pressing Enter will have no effect. You can enable the allow_arbitrary_symbol_search_input featureset to use the old behavior.

  • Change custom translation API. Change the custom_translate_function interface to accept different parameters: the original text, the singular original text, and the translated text. For example "prices", "price", "prix".

  • Changed the behavior of data display in the Depth of Market widget. Now, data is displayed in static mode. This means that the price series is fixed, while the current price moves within, above, or below the designated range. To center on the current price, click the centering button () or use the Shift + Alt/Option + C shortcut. Previously, centering was applied dynamically.

  • Renamed the Symbol Info dialog. The Symbol Info dialog and the corresponding items in context menus are called Security Info now. #8444

  • Renamed ErrorCallback to DatafeedErrorCallback. ErrorCallback used in IDatafeedChartApi has been renamed to DatafeedErrorCallback.

  • Updated selectedCurrency behavior. In CurrencyInfo, the selectedCurrency property now returns null instead of "Mixed" when price scales contain mixed currencies.

  • Deprecated property. The brokerConfig property in the TradingTerminalWidgetOptions interface is deprecated and will be removed in the next major release. Use the broker_config property instead.

New Features

  • New Custom themes API. This API allows you to customize colors of the chart elements including toolbars, dialogs, and buttons. To do this, you should specify your own theme with a custom color palette. For more information, refer to the Custom themes API article.
  • Added Volume Candles chart style. This chart style allows for a visual assessment of the volume of trades for each candle. These are still candlesticks, but the width of each candle depends on the volume of trades during the period of formation of this candle. The greater the trading volume during the formation period of the candle, the larger the width of the candle. To display Volume Candles, select the corresponding option in the drop-down menu on the top toolbar.

Improvements

  • Behavior change for chartContextMenuActions. When the chartContextMenuActions method returns an empty array, the Trade item within the chart context menu will not be displayed. Previously, the item was rendered but grayed out.

    Trading Platform Only

  • Added the library_custom_fields property to the LibrarySymbolInfo interface. This property is used to include additional metadata in the symbol information. The metadata will not be processed by the library.

  • Added extra properties to symbolExt method. The symbolExt method now returns additional properties including ticker.

  • Added the debug_broker option to the Widget Constructor. When debug_broker is specified, the library logs calls and responses to IBrokerWithoutRealtime and IBrokerConnectionAdapterHost in the browser console. You can set debug_broker to one of the debug levels defined by BrokerDebugMode.

    Trading Platform Only

  • Updated the Anchored VWAP drawing. Add bands settings to the Anchored VWAP drawing.

  • Added new methods to the Trading Host. The getOrderTicketSetting and setOrderTicketSetting methods have been added to the IBrokerConnectionAdapterHost interface. These methods allow you to read and adjust Order Ticket settings.

    Trading Platform Only

  • Changed const enum to enum in the library type declarations. This change allows you to import enums from the library in a TypeScript environment with the isolatedModules option enabled, such as when using Vite or similar tools.

  • Added the hideStudiesFromLegend option to ClientSnapshotOptions. When hideStudiesFromLegend is set to true, the legend within the generated screenshots won't contain any studies applied to the chart.

  • Exposed connectionStatusUpdate from IBrokerConnectionAdapterHost. An existing connectionStatusUpdate API has been exposed for IBrokerConnectionAdapterHost to help reflect connection status changes throughout the application lifecycle.

    Trading Platform Only

  • New keyboard shortcuts. The following shortcuts were added:

    • Shift + Mouse wheel — scroll the chart horizontally
    • Shift + Alt + B — place limit order to buy
    • Shift + Alt + S — place limit order to sell

  • Enabled in-place editing for drawing texts. For the following drawings, users can now add custom text and edit it on the chart:

    • Fib Retracement
    • Trend-based Fib Extension
    • Horizontal and Vertical Line
    • Trend Line
    • Info Line
    • Ray
    • Extended Line
    • Signpost
    • Note
    • Anchored Note
    • Comment
    • Rectangle
    • Ellipse
    • Circle

    To enter the text, users should click the +Add text placeholder that appears on hover.

  • Disabled color pickers in Chart settings. If a certain price label or line is hidden on the chart, users cannot adjust the color of this label/line in the Chart settings dialog.

  • Time zones. Time zone updates:

    • Changed the Almaty (UTC+6) time zone to Astana (UTC+5).
    • Added the new Kuala Lumpur (UTC+8) time zone.

  • Visibility of price labels for risk-reward drawings. Previously, price labels for the Long position and Short position drawings could be either hidden entirely or always displayed. Now, if the price labels are disabled for a certain drawing, the labels will be displayed when the drawing is selected.

  • Accessibility improvement. Users can now select the following elements in the Legend when navigating with the keyboard.

    • The More () button and items in the corresponding menu
    • The Remove () button

  • Added new multiple-chart layouts combinations.

    Trading Platform Only

  • New style settings for the Note drawing. Now:

    • The Background and Border settings are optional.
    • The default color of the drawing depends on the current chart theme.

Bug Fixes

  • Fixed the Pivot Points Standard compatibility with Japanese chart types. The Pivot Points Standard indicator used to cause the Assertion failed: data must have unique sorted times error when applied to chart types such as Line Break, Renko, Kagi, and Point-and-Figure under certain data conditions.
  • Workaround for corrupted chart layouts. In rare cases, chart layouts can become corrupted and cause a DEFAULT_SYMBOL is not defined error when loaded by the library. To work around this error, set symbol to be used as a fallback for any corrupted charts.
  • Fixed an issue where 0-volume data were not displayed in the Legend. #8662
  • Fixed the time indicator. The time indicator now correctly moves across the timeline in the Market Status pop-up.
  • Fixed resizing for risk-reward tools. The resizing of Long position and Short position drawings works correctly now. #8513
  • Fixed changing of drawing coordinates. The setting dialog used to crash when users changed coordinates of drawings such as Anchored Volume Profile, Fixed Range Volume Profile, and Regression Trend.
  • Fixed the drawing settings bug. Previously, when users clicked Hide/Show on a drawing, the settings applied to this drawing would override the default ones. Now, changing drawing visibility does not affect the default settings. #8434
  • Fixed colors of the scale buttons. The colors of the A (auto) and L (log) scale buttons match the chart background color now. #8459
  • Fixed bugs on the multiple-chart layout.
    Trading Platform Only
    The following bugs were fixed:
    • The Long/Short Position drawing used to cause errors if the drawing was hidden for a certain resolution and that resolution was currently displayed on the chart.
    • Synchronized Path and Polyline drawings were not displayed on larger resolutions if the first two points of the drawing were set at the same level on a smaller resolution.
    • The Curve and Double Curve drawings used to cause errors if a user moved the drawing before enabling layout synchronization.
    • Changing the Profit/Stop level of the synchronized Long/Short Position drawing used to cause errors if the drawing was hidden for a certain resolution and that resolution was currently displayed on the chart.

Version 27.006​

Date: Tue May 21 2024

Bug Fixes

  • Resolve quotes with ticker instead of symbol name. The library will now request quote data using the ticker property.

Version 27.005​

Date: Tue May 07 2024

Improvements

  • Update the Anchored AVWAP drawing. Add bands settings to the Anchored VWAP drawing.

Date: Wed Apr 17 2024

Breaking Changes

  • Fixed time parameters in CrossHairMovedEventParams. In version 26.001, we changed the time property of CrossHairMovedEventParams to be a timestamp in the selected time zone.

Improvements

  • Added ability to disable pulse animation when chart type is set to Line. New disable_pulse_animation featureset allows users to disable the pulse animation when chart type is set to Line.

Bug Fixes

  • Fixed the price scale placement. The price scale should be placed back to its original position when a change made through the Settings dialog is canceled. Fixes #4991
  • Fixed the 52 Week High/Low indicator issue. The 52 Week High/Low indicator no longer adds an empty space to the price scale when less than 52 weeks of historic bars are available. Fixes #8137 #8469
  • Only calculate VWAP value when entire anchor period is loaded. The VWAP indicator will only calculate values for the input anchor period if all bars in that period have been loaded.
  • Fixed a trailing stop modification dialog error. Fixed a problem where opening the Order Ticket for a trailing stop position caused a "ReferenceError: isPositionLikeItem is not defined" error to be thrown.
  • Fixed the incorrect point position for the Long Position drawing. The getPositionPoints() method will now return correct point positions. Fixes #8230
  • BREAKING CHANGE Position line price label does not use the correct price formatter. The price scale will now correctly reflect the value when a formatter is used with createPositionLine.

    Trading Platform Only
  • Added a new type that reflects the ID of the created indicator. A new study_event type was added: create. It returns the id of the newly created indicator.

Bug Fixes

  • Displaying volume indicator on chart load when visible_plots_set is not specified. The chart will now correctly display the volume indicator if the create_volume_indicator_by_default featureset is enabled even if the symbols LibrarySymbolInfo doesn't specify the optional visible_plots_set property.
  • Prioritise widget constructor symbol over saved state. The symbol property in the widget constructor will now have priority over symbols loaded from saved chart states when using saved_data or load_last_chart. Fixes #7922 #8473 #7926 #8168
