Constructor & Destructor Documentation

◆ IntrinioEconomicData() [1/2]

QuantConnect.Data.Custom.Intrinio.IntrinioEconomicData.IntrinioEconomicData ( )

Initializes a new instance of the IntrinioEconomicData class.

Definition at line 93 of file IntrinioEconomicData.cs.

◆ IntrinioEconomicData() [2/2]

QuantConnect.Data.Custom.Intrinio.IntrinioEconomicData.IntrinioEconomicData ( IntrinioDataTransformation dataTransformation )

Initializes a new instance of the IntrinioEconomicData class.

Parameters

dataTransformation The item.

Definition at line 101 of file IntrinioEconomicData.cs.

Member Function Documentation

◆ GetSource()

override SubscriptionDataSource QuantConnect.Data.Custom.Intrinio.IntrinioEconomicData.GetSource	(	SubscriptionDataConfig	config,
		DateTime	date,
		bool	isLiveMode
	)

virtual

Return the URL string source of the file. This will be converted to a stream

Parameters

config	Configuration object
date	Date of this source file
isLiveMode	true if we're in live mode, false for backtesting mode

Returns: String URL of source file.

Given Intrinio's API limits, we cannot make more than one CSV request per second. That's why in backtesting mode we make sure we make just one call to retrieve all the data needed. Also, to avoid the problem of many sources asking the data at the beginning of the algorithm, a pause of a second is added.

Reimplemented from QuantConnect.Data.BaseData.

◆ Reader()

override BaseData QuantConnect.Data.Custom.Intrinio.IntrinioEconomicData.Reader	(	SubscriptionDataConfig	config,
		string	line,
		DateTime	date,
		bool	isLiveMode
	)

virtual

Reader converts each line of the data source into BaseData objects. Each data type creates its own factory method, and returns a new instance of the object each time it is called. The returned object is assumed to be time stamped in the config.ExchangeTimeZone.

Parameters

config	Subscription data config setup object
line	Line of the source document
date	Date of the requested data
isLiveMode	true if we're in live mode, false for backtesting mode

Returns: Instance of the T:BaseData object generated by this line of the CSV
