We do our best to make every next version fully compartible 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 Charting Library version by executing TradingView.version() in a browser console.

Here is the list of breaking changes:

Version 1.12

Charting Library

• charting_library/charting_library.min.js now is UMD module.
  If you just inline this script into HTML - nothing changed.
  But if import it as a module you should import widget, version and onready functions straight 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 previous versions you had to use overrides and applyOverrides). See [[Studies-Overrides|Studies-Overrides]] page.
• Since this version you cannot override showStudyArguments and showLastValue using options keyword.

Trading Terminal

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

The following stuff is still supported in Trading Terminal, but will be deprecated in future versions:

• subscribePL and unsubscribePL. The broker should call plUpdate method of the Host every time when the profit is changed.
• supportDOM 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 removed. Broker API should update [[Broker API|Trading-Host]] 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 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 stuff is still supported in Trading Terminal, but will be deprecated in future versions:

• supportDOME renamed to supportDOM.
• Changed signature of `showClosePositionDialog.
• showEditBracketsDialog renamed to showPositionBracketsDialog, changed signature.

Version 1.10

• Default behavior of Volume indicator is 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 on first load of an empty chart if it is supported by an active instrument.

Version 1.9

• We don't compile Pine scripts anymore. You can still use scripts compiled before.

Version 1.8 of Trading Terminal

• Chart has no option to show only actual orders anymore. Appropriate methods have been removed.
• showOrderDialog receives an object instead of arguments list
• showSampleOrderDialog removed, use [[showOrderDialog|Trading-Host#showorderdialogorder-handler]] instead
• showOrderDialog removed from [[Broker API|Broker API]], use placeOrder and modifyOrder receive silently argument instead
• reversePosition, closePosition, cancelOrder have an additional argument silently. They should should appropriate dialogs by themselves from now.

Version 1.7

• Since this version it is not enough to call setSymbol with the same symbol. 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 any more. 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 property. 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.*

• Override mainSeriesProperties.candleStyle.wickColor is not supported anymore.
  Use mainSeriesProperties.candleStyle.wickUpColor and mainSeriesProperties.candleStyle.wickDownColor
