Detailed Description

Algorithm manager class executes the algorithm and generates and passes through the algorithm events.

Definition at line 46 of file AlgorithmManager.cs.

Constructor & Destructor Documentation

◆ AlgorithmManager()

QuantConnect.Lean.Engine.AlgorithmManager.AlgorithmManager	(	bool	liveMode,
		AlgorithmNodePacket	job = `null`
	)

Initializes a new instance of the AlgorithmManager class

Parameters

liveMode	True if we're running in live mode, false for backtest mode
job	Provided by LEAN when creating a new algo manager. This is the job that the algo manager is about to execute. Research and other consumers can provide the default value of null
