Breaking Changes - kroim/charting-library-wiki GitHub Wiki

We do our best to make every next version fully compatible with the previous one, but sometimes big changes requires you to make minor changes in your code when upgrading to a new version.

Note: you can check the Charting Library version by executing TradingView.version() in a browser console.

Here is the list of breaking changes:

  • The Chart Method removeEntity now can be undone by the user by default. To disable this, please use disableUndo field in the new argument options.

Trading Terminal

Version 1.15

  • Featureset show_logo_on_all_charts has been removed.
  • Featureset cl_feed_return_all_data has been removed.
  • Action magnetAction from executeActionById and getCheckableActionState methods is removed. Use magnetEnabled instead.

  • Override symbolWatermarkProperties is not supported anymore. You can use settings_adapter with symbolWatermark key.
  • indicators_file_name constructor option was removed. Use custom_indicators_getter instead. We made this change to speed up the loading of the library and get rid of possible vulnerabilities that may occur when loading a file. You just need to move the code of your custom indicators from the JS file to the widget constructor, wrapping them in a function and a Promise

Trading Terminal

We've changed the broker's interaction flow. Please read the following carefully to understand what changes should be made in your code to switch to the new version.

Till now the Trading Terminal called broker adapter's methods (e.g. placeOrder, modifyOrder) when user clicked on Buy/Sell/Modify buttons. When calling these methods the Trading Terminal passed a silently argument. When silently was set to true, the broker adapter could send an order without showing the dialog. When it was set to false, the broker adapter had to invoke a method from the host to show the order ticket (or the Edit Position dialog).

Starting from 1.15 the Trading Terminal shows all dialogs by itself and invokes broker adapter's methods to send an order or a position to the broker's server. The reason for this change is that we've added an order panel that can be used to place an order at any time. If you use your own order dialog then you still need to make changes in your broker adapter's methods, but additionally you need to use metainfo to pass the dialog constructor to the Trading Terminal.

  • Argument silently was removed from placeOrder, modifyOrder, reversePosition, closePosition, closeTrade, cancelOrder, cancelOrders methods of the Broker API.

  • Arguments handler and options were removed from showOrderDailog method of the Trading Host.

  • Argument handler was removed from showPositionBracketsDailog method of the Trading Host.

  • supportCustomPlaceOrderTradableCheck flag is no longer supported.

  • We pass the parent order to modifyOrder if it exists. If child order’s details are required while modifying the order you can get back this behavior by enabling always_pass_called_order_to_modify featureset.

Version 1.14

  • createButton returns HTMLElement instead of JQuery.
  • createButton must be used after headerReady() Promise is resolved.
  • getVisibleRange returns {from, to} in the UTC timezone (it was a timezone selected on a chart before).
  • Method onready was removed. You can use window.addEventListener('DOMContentLoaded', callback, false) instead.
  • saveAsSnapshot parameter was removed from saveChartToServer

TypeScript type definitions

  • StudyInputValueType type is renamed to StudyInputValue.

Featureset

  • Starting from this version you are no longer able to use the keep_left_toolbar_visible_on_small_screens featureset. This featureset is removed and the left toolbar visibility no longer depends on the screen size.

Version 1.13

Version 1.12

Charting Library

  • charting_library/charting_library.min.js is now UMD module.

    If you only inline this script into HTML then nothing has changed for you. If you import it as a module you should import widget, version and onready functions directly from it.

  • searchSymbolsByName is removed from JS-API, use searchSymbols instead.

Study overrides:

  • Overrides for Overlay should be applied only via studies_overrides (and applyStudiesOverrides in runtime). In the previous versions you had to use overrides and applyOverrides). See Studies-Overrides page.
  • Starting from this version you are no longer able to override showStudyArguments and showLastValue using options keyword.

Trading Terminal

  • hasHistory flag is removed. Use historyColumns to display History in the Account Manager.

The following items are still supported in the Trading Terminal, but will be deprecated in future versions:

  • subscribePL and unsubscribePL. The broker should call plUpdate method of the Host every time the profit is changed.
  • supportDOM is removed. DOM widget visibility can be set using dome_widget featureset.

The Trading Controller is replaced with Broker API.

The following changes should be applied to your Trading Controller implementation to move to new Broker API:

  • Method setHost is removed. Host should be passed to the constructor of Broker API.
  • Method buttonDropdownItems is removed. Broker API should update Broker API using setButtonDropdownActions.
  • Methods configFlags and durations are removed. Use Widget Constructor fields instead.
  • All methods that returned $.Deferred should be modified to return Promise.
  • Method chartContextMenuItems is renamed to chartContextMenuActions.
  • Method isTradable changed to return a Promise instead of a Boolean value.
  • All string constants ("working", "buy" etc.) should be replaced with the appropriate number of constants.
  • Position avg_price renamed to avgPrice.
  • tradingController field in the Widget Constructor is removed. Use brokerFactory instead.

Version 1.11

Trading Terminal

The following items are still supported in Trading Terminal, but will be deprecated in future versions:

  • supportDOME renamed to supportDOM.
  • The signature of `showClosePositionDialog has been changed.
  • showEditBracketsDialog was renamed to showPositionBracketsDialog.The signature has been changed.

Version 1.10

  • Default behavior of Volume indicator was changed.

    Previous behavior: Volume indicator is added/removed when an instrument or a resolution is switched depending on volume support by the instrument. You can get back to this behavior by disabling create_volume_indicator_by_default_once featureset.

    New behavior: Volume indicator is added when an empty chart is loaded for the first time provided that it is supported by an active instrument.

Version 1.9

  • We don't compile Pine scripts anymore. You can still use scripts that were compiled earlier.

Version 1.8 of Trading Terminal

  • The chart can no longer show active orders only. Appropriate methods have been removed.
  • showOrderDialog receives an object instead of arguments list
  • showSampleOrderDialog removed, use showOrderDialog instead
  • showOrderDialog removed from Broker API, use placeOrder and modifyOrder receive silently argument instead
  • reversePosition, closePosition, cancelOrder have an additional argument silently.

Version 1.7

  • Starting from this version calling setSymbol with the same symbol is no longer enough. You should call onResetCacheNeededCallback from subscribeBars first. Then you can use setSymbol or new resetData method of the chart.
  • JSAPI protocol version 1 is not supported anymore. nextTime and noData must be provided.

Version 1.5

  • Added source argument to MACD. You should change MACD creation code to pass source also.

    chartWidget.chart().createStudy('MACD', false, false, [12, 26, "close", 9])

Version 1.4

  • Override transparency is not supported anymore. We added transparency support to every color. Use rgba form to define a color with transparency. Example:

    "symbolWatermarkProperties.color" : "rgba(60, 70, 80, 0.05)"

Version 1.3

  • Override paneProperties.gridProperties.* is not supported anymore.

    Please use paneProperties.vertGridProperties.* and paneProperties.horzGridProperties.*

    Use mainSeriesProperties.candleStyle.wickUpColor and mainSeriesProperties.candleStyle.wickDownColor
