data_status​

• Optional data_status: "streaming" | "endofday" | "delayed_streaming"

The status code of a series with this symbol. For delayed_streaming and endofday type of data, the status is displayed as an icon and the Data is delayed section in the Legend, next to the market status icon. Note that you should also enable the display_data_mode featureset.

When declaring delayed_streaming you also have to specify its LibrarySymbolInfo.delay in seconds.

delay​

• Optional delay: number

Type of delay that is associated to the data or real delay for real time data.

  • 0 for realtime

• exchange: string

Traded exchange (current (proxy) exchange). The name will be displayed in the chart legend for this symbol.

Example

"NYSE"

• Optional exchange_logo: string

URL of image to be displayed as the logo for the exchange. The show_exchange_logos featureset needs to be enabled for this to be visible in the UI.

The image should ideally be square in dimension. You can use any image type which the browser supports natively. Simple SVG images are recommended.

Examples:

  • https://yourserver.com/exchangeLogo.svg
  • /images/myImage.png
  • data:image/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL3...

expired​

• Optional expired: boolean

Boolean showing whether this symbol is expired futures contract or not.

Default

false

format​

• format: SeriesFormat

Format of displaying labels on the price scale:

price - formats decimal or fractional numbers based on minmov, pricescale, minmove2, fractional and variableMinTick values. See Price format for more details. volume - formats decimal numbers in thousands, millions, billions or trillions

fractional​

• Optional fractional: boolean

For common prices this can be skipped.

Fractional prices are displayed 2 different forms: 1) xx'yy (for example, 133'21) 2) xx'yy'zz (for example, 133'21'5).

  • xx is an integer part.
  • minmov/pricescale is a Fraction.
  • minmove2 is used in form 2.
  • fractional is true.
  • variableMinTick is skipped.

Example:

If minmov = 1, pricescale = 128 and minmove2 = 4:

  • 119'16'0 represents 119 + 16/32
  • 119'16'2 represents 119 + 16.25/32
  • 119'16'5 represents 119 + 16.5/32
  • 119'16'7 represents 119 + 16.75/32

More examples:

  • ZBM2014 (T-Bond) with 1/32: minmov = 1, pricescale = 32, minmove2 = 0
  • ZCM2014 (Corn) with 2/8: minmov = 2, pricescale = 8, minmove2 = 0
  • ZFM2014 (5 year t-note) with 1/4 of 1/32: minmov = 1, pricescale = 128, minmove2 = 4

has_daily​

• Optional has_daily: boolean

The boolean value specifying whether the datafeed can supply historical data at the daily resolution.

If has_daily is set to false, all buttons for resolutions that include days are disabled for this particular symbol. Otherwise, the library requests daily bars from the datafeed. All daily resolutions that the datafeed supplies must be included in the LibrarySymbolInfo.daily_multipliers array.

Default

true

has_empty_bars​

• Optional has_empty_bars: boolean

The boolean value showing whether the library should generate empty bars in the session when there is no data from the data feed for this particular time.

I.e., if your session is 0900-1600 and your data has gaps between 11:00 and 12:00 and your has_empty_bars is true, then the Library will fill the gaps with bars for this time.

Flag has_empty_bars = true cannot be used if featureset disable_resolution_rebuild is enabled.

Default

false

has_intraday​

• Optional has_intraday: boolean

Boolean value showing whether the symbol includes intraday (minutes) historical data.

If it's false then all buttons for intraday resolutions will be disabled for this particular symbol. If it is set to true, all intradays resolutions that are supplied directly by the datafeed must be provided in intraday_multipliers array.

WARNING Any daily, weekly or monthly resolutions cannot be inferred from intraday resolutions.

false if DWM only

Default

false

has_seconds​

• Optional has_seconds: boolean

Boolean value showing whether the symbol includes seconds in the historical data.

If it's false then all buttons for resolutions that include seconds will be disabled for this particular symbol.

If it is set to true, all resolutions that are supplied directly by the data feed must be provided in seconds_multipliers array.

Default

false

has_ticks​

• Optional has_ticks: boolean

Boolean value showing whether the symbol includes ticks in the historical data.

If it's false then all buttons for resolutions that include ticks will be disabled for this particular symbol.

Default

false

has_weekly_and_monthly​

• Optional has_weekly_and_monthly: boolean

The boolean value showing whether data feed has its own weekly and monthly resolution bars or not.

If has_weekly_and_monthly = false then the library will build the respective resolutions using daily bars by itself. If not, then it will request those bars from the data feed using either the weekly_multipliers or monthly_multipliers if specified. If resolution is not within either list an error will be raised.

Default

false

industry​

• Optional industry: string

Industry for stocks to be displayed in the Symbol Info.

intraday_multipliers​

• Optional intraday_multipliers: string[]

Array of resolutions (in minutes) supported directly by the data feed. Each such resolution may be passed to, and should be implemented by, getBars. The default of [] means that the data feed supports aggregating by any number of minutes.

If the data feed only supports certain minute resolutions but not the requested resolution, getBars will be called (repeatedly if needed) with a higher resolution as a parameter, in order to build the requested resolution.

For example, if the data feed only supports minute resolution, set intraday_multipliers to ['1'].

When the user wants to see 5-minute data, getBars will be called with the resolution set to 1 until the library builds all the 5-minute resolution by itself.

Example

(for ex.: "1,5,60") - only these resolutions will be requested, all others will be built using them if possible

Default

[]

listed_exchange​

• listed_exchange: string

short name of the exchange where this symbol is traded (real listed exchange). The name will be displayed in the chart legend for this symbol.

Example

"NYSE"

logo_urls​

• Optional logo_urls: [string, string] | [string]

URL of image/s to be displayed as the logo/s for the symbol. The show_symbol_logos featureset needs to be enabled for this to be visible in the UI.

  • If a single url is returned then that url will solely be used to display the symbol logo.
  • If two urls are provided then the images will be displayed as two partially overlapping circles with the first url appearing on top. This is typically used for FOREX where you would like to display two country flags are the symbol logo.

The image/s should ideally be square in dimension. You can use any image type which the browser supports natively.

Examples:

  • https://yourserver.com/apple.svg
  • /images/myImage.png
  • data:image/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL3...
  • data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAASABIAAD/4...

long_description​

• Optional long_description: string

Symbol Long description

Optional long(er) description for the symbol.

minmov​

• minmov: number

The number of units that make up one tick.

Example

For example, U.S. equities are quotes in decimals, and tick in decimals, and can go up +/- .01. So the tick increment is 1. But the e-mini S&P futures contract, though quoted in decimals, goes up in .25 increments, so the tick increment is 25. (see also Tick Size)

minmove2​

• Optional minmove2: number

For common prices this can be skipped.

Example

Quarters of 1/32: pricescale=128, minmovement=1, minmovement2=4

monthly_multipliers​

• Optional monthly_multipliers: string[]

Array (of strings) containing the resolutions (in months - without the suffix) supported by the data feed. ResolutionString

For example it could be something like

monthly_multipliers = ['1', '3', '4', '12'];

Default

['1']

name​

• name: string

It is a symbol name within an exchange, such as AAPL or 9988 (Hong Kong). Note that it should not contain the exchange name. This symbol name is visible to users and can be repeated.

By default, name is used to resolve symbols in the Datafeed API. If you use LibrarySymbolInfo.ticker, the library will use the ticker for Datafeed API requests.

original_currency_code​

• Optional original_currency_code: string

The currency in which the instrument is traded.

original_unit_id​

• Optional original_unit_id: string

A unique identifier of a unit in which the instrument is traded.

price_source_id​

• Optional price_source_id: string

Optional ID of a price source for a symbol. Should match one of the price sources from the price_sources array.

Note that you should set the symbol_info_price_source featureset to true to display the symbol price source in the main series legend.

price_sources​

• Optional price_sources: SymbolInfoPriceSource[]

Supported price sources for the symbol. Price sources appear in the series legend and indicate the origin of values represented by symbol bars. Example price sources: "Spot Price", "Ask", "Bid", etc. The price source information is valuable when viewing non-OHLC series types.

Note that you should set the symbol_info_price_source featureset to true to display the symbol price source in the main series legend.

Example

[{ id: '1', name: 'Spot Price' }, { id: '321', name: 'Bid' }]

pricescale​

• pricescale: number

Code (Tick)

Example

8/16/.../256 (1/8/100 1/16/100 ... 1/256/100) or 1/10/.../10000000 (1 0.1 ... 0.0000001)

seconds_multipliers​

• Optional seconds_multipliers: string[]

It is an array containing resolutions that include seconds (excluding postfix) that the data feed provides. E.g., if the data feed supports resolutions such as ["1S", "5S", "15S"], but has 1-second bars for some symbols then you should set seconds_multipliers of this symbol to [1]. This will make the library build 5S and 15S resolutions by itself.

sector​

• Optional sector: string

Sector for stocks to be displayed in the Symbol Info.

session​

• session: string

Trading hours for this symbol. See the Trading sessions article to learn more details.

Example

• Optional session_display: string

The session value to display in the UI. If not specified, then session is used.

session_holidays​

• Optional session_holidays: string

A string that contains a list of non-trading holidays for the symbol. Holiday dates should be in the YYYYMMDD format. These dates are not displayed on the chart.

You can specify a correction for a holiday using LibrarySymbolInfo.corrections.

Example

"20181105,20181107,20181112"

subsession_id​

• Optional subsession_id: string

An ID of a subsession specified in subsessions. The value must match the subsession that is currently displayed on the chart. For more information, refer to the Extended sessions section.

subsessions​

• Optional subsessions: LibrarySubsessionInfo[]

An array of objects that contain information about certain subsessions within the extended session. For more information, refer to the Extended sessions section.

supported_resolutions​

• Optional supported_resolutions: ResolutionString[]

An array of resolutions which should be enabled in the Resolution drop-down menu for this symbol. Each item of the array is expected to be a string that has a specific format.

If one changes the symbol and the new symbol does not support the selected resolution, the resolution will be switched to the first available one in the list.

Resolution availability logic (pseudocode):

resolutionAvailable  =
    resolution.isIntraday
        ? symbol.has_intraday && symbol.supported_resolutions(resolution)
        : symbol.supported_resolutions(resolution);

If supported_resolutions is [] (empty array), all resolutions are disabled in the Resolution drop-down menu.

If supported_resolutions is undefined, all resolutions that the chart support (DatafeedConfiguration.supported_resolutions) and custom resolutions are enabled.

Note that the list of available time frames depends on supported resolutions. Time frames that require resolutions that are unavailable for a particular symbol will be hidden. Refer to Time frame toolbar for more information.

ticker​

• Optional ticker: string

It is an unique identifier for a particular symbol in your symbology. If you specify this property, its value will be used for all data requests for this symbol. ticker will be treated the same as LibrarySymbolInfo.name if not specified explicitly. Note that it should not contain the exchange name.

timezone​

variable_tick_size​

• Optional variable_tick_size: string

Dynamic minimum price movement. It is used if the instrument's minimum price movement changes depending on the price range.

For example, '0.01 10 0.02 25 0.05', where the tick size is 0.01 for a price less than 10, the tick size is 0.02 for a price less than 25, the tick size is 0.05 for a price greater than or equal to 25.

visible_plots_set​

• Optional visible_plots_set: VisiblePlotsSet

Represents what values are supported by the symbol. Possible values:

  • ohlcv — the symbol supports open, high, low, close prices and has volume.
  • ohlc — the symbol supports open, high, low, close, prices but doesn't have volume.
  • c — the symbol supports only close price. This makes the chart show the symbol data using only line-based styles.

Default

'ohlcv'

volume_precision​

• Optional volume_precision: number
