Bases: Ticker

Representation of Quandl tickers.

Parameters:

• ticker (str) – string containing series ID within a specific database

• database_name (str) – name of the database where the series is located

• database_type (QuandlDBType) – type of the database

• point_value (int) – size of the contract as given by the ticker’s Data Provider. Used mostly by tickers of security_type FUTURE and by default equals 1.

• currency (str) – ISO code of the currency of the ticker. Example “USD”.

Methods:

as_string()	Returns a string representation of a ticker
from_string(ticker_str[, db_type, ...])	Example: QuandlTicker.from_string('WIKI/MSFT') Note: this method supports only the Timeseries tickers at the moment.

Attributes:

name	Returns a name of the ticker.

as_string() → str

Returns a string representation of a ticker

classmethod from_string(ticker_str: Union[str, Sequence[str]], db_type: QuandlDBType = QuandlDBType.Timeseries, security_type: SecurityType = SecurityType.STOCK, point_value: int = 1, currency: Optional[str] = None) → Union[QuandlTicker, Sequence[QuandlTicker]]

Example: QuandlTicker.from_string(‘WIKI/MSFT’) Note: this method supports only the Timeseries tickers at the moment.

property name: str

Returns a name of the ticker. The property should be adjusted for different Ticker classes to provide a string representation of a Ticker, which in some cases could be more understandable than the output of as_string() function.
