LibrarySymbolInfo.base_name

build_seconds_from_ticks​

• Optional build_seconds_from_ticks: boolean

The boolean value showing whether or not seconds bars for this symbol can be built from ticks. Only available in Trading Platform.

The library builds resolutions from ticks only if there are no seconds resolutions from the datafeed or the provided resolutions are larger then the required one. For example, the datafeed provides 3S resolution. In this case, the library can build only 1S or 2S resolutions from ticks. Resolutions such as 15S will be build with seconds bars.

Default

false

Inherited from​

LibrarySymbolInfo.price_sources

pricescale​

• pricescale: number

A number of decimal places or fractions that the price has.

The pricescale value depends on the price format. If you want to display the price in the decimal format, pricescale should be 10^n, where n is the number of decimal places. Examples: 1, 10, 10000000.

If you want to display the price in the fractional format, pricescale should be 2^n. This value represents the number of fractions. Examples: 8, 16, 256.

seconds_multipliers​

• Optional seconds_multipliers: string[]

An array of seconds resolutions that your datafeed supports. Items in the array should be listed in ascending order and should not include letters, for example: ["1", "2"]. This property is required to enable seconds resolutions. Refer to the Resolution article for more information.

The library also uses resolutions listed in seconds_multipliers to display higher resolution that your datafeed does not explicitly support. If seconds_multipliers is not specified, the library cannot build additional resolutions. Consider the example. You need to enable one-second and five-second resolutions but your datafeed contains only one-second data. In this case, you should set seconds_multipliers to ["1"]. The library will build the five-second resolution from one-second data.
