For example it could be something like

daily_multipliers = ['1', '3', '4', '6', '7'];

Example

"NYSE"

Type

string


expiration_date

Optional

Unix timestamp of the expiration date. One must set this value when expired = true. Charting Library will request data for this symbol starting from that time point.

Type

number


expired

Optional

Type

boolean


format

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 Formatting for more details volume - formats decimal numbers in thousands, millions, billions or trillions

Type

SeriesFormat


fractional

Optional

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

Type

Type

string


has_daily

Optional

The boolean value showing whether data feed has its own daily resolution bars or not.

If has_daily = false then Charting Library will build the respective resolutions using 1-minute bars by itself. If not, then it will request those bars from the data feed only if specified resolution belongs to daily_multipliers, otherwise an error will be thrown.

Default

true

Type

boolean


has_empty_bars

Optional

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

Type

boolean


has_intraday

Optional

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

Type

boolean


has_no_volume

DeprecatedOptional

Type

boolean


has_seconds

Optional

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

Type

boolean


has_ticks

Optional

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

Type

boolean


has_weekly_and_monthly

Optional

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

If has_weekly_and_monthly = false then Charting 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

Type

boolean


holidays

DeprecatedOptional

Type

string


industry

Optional

Industry for stocks to be displayed in the Symbol Info.

Type

string


intraday_multipliers

Optional

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

[]

Type

string[]


listed_exchange

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"

Type

string


long_description

Optional

Symbol Long description

Optional long(er) description for the symbol.

Type

string


minmov

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)

Type

number


minmove2

Optional

For common prices this can be skipped.

Example

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

Type

number


monthly_multipliers

Optional

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']

Type

Type

number


seconds_multipliers

Optional

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 Charting Library build 5S and 15S resolutions by itself.

Type

supported_resolutions

An array of resolutions which should be enabled in resolutions picker for this symbol.

Each item of an array is expected to be a string. Format is described in another article.

If one changes the symbol and new symbol does not support the selected resolution then 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);

In case of absence of supported_resolutions in a symbol info all DWM resolutions will be available. Intraday resolutions will be available if has_intraday is true. Supported resolutions affect available timeframes too. The timeframe will not be available if it requires the resolution that is not supported.

Type

ResolutionString[]
