Member Function Documentation

◆ Reader()

override BaseData QuantConnect.Data.UniverseSelection.FutureUniverse.Reader	(	SubscriptionDataConfig	config,
		StreamReader	stream,
		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.

Parameters

config	Subscription data config setup object
stream	Stream reader 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

Reimplemented from QuantConnect.Data.BaseData.

Definition at line 58 of file FutureUniverse.cs.

Here is the call graph for this function:

◆ Clone()

override BaseData QuantConnect.Data.UniverseSelection.FutureUniverse.Clone ( )

virtual

Creates a copy of the instance

Returns: Clone of the instance

Reimplemented from QuantConnect.Data.UniverseSelection.BaseDataCollection.

Definition at line 72 of file FutureUniverse.cs.

Here is the call graph for this function:

◆ DefaultResolution()

override Resolution QuantConnect.Data.UniverseSelection.FutureUniverse.DefaultResolution ( )

virtual

Gets the default resolution for this data and security type

This is a method and not a property so that python custom data types can override it

Reimplemented from QuantConnect.Data.UniverseSelection.BaseChainUniverseData.

Definition at line 82 of file FutureUniverse.cs.

◆ operator Symbol()

static implicit QuantConnect.Data.UniverseSelection.FutureUniverse.operator Symbol ( FutureUniverse data )

static

Implicit conversion into Symbol

Parameters

data	The option universe data to be converted

Definition at line 92 of file FutureUniverse.cs.

◆ ToCsv()

static string QuantConnect.Data.UniverseSelection.FutureUniverse.ToCsv	(	Symbol	symbol,
		decimal	open,
		decimal	high,
		decimal	low,
		decimal	close,
		decimal	volume,
		decimal?	openInterest
	)

static

Gets the CSV string representation of this universe entry

Definition at line 101 of file FutureUniverse.cs.

Member Data Documentation

◆ CsvHeader

string QuantConnect.Data.UniverseSelection.FutureUniverse.CsvHeader => "symbol_id,symbol_value,open,high,low,close,volume,open_interest"

static

Gets the CSV header string for this universe entry

Definition at line 109 of file FutureUniverse.cs.
