QuantConnect.Algorithm.Framework.Portfolio.EqualWeightingPortfolioConstructionModel Class Reference

Provides an implementation of IPortfolioConstructionModel that gives equal weighting to all securities. The target percent holdings of each security is 1/N where N is the number of securities. For insights of direction InsightDirection.Up, long targets are returned and for insights of direction InsightDirection.Down, short targets are returned. More...

Constructor & Destructor Documentation

◆ EqualWeightingPortfolioConstructionModel() [1/6]

QuantConnect.Algorithm.Framework.Portfolio.EqualWeightingPortfolioConstructionModel.EqualWeightingPortfolioConstructionModel ( IDateRule  rebalancingDateRules,
PortfolioBias  portfolioBias = PortfolioBias.LongShort 
)

Initialize a new instance of EqualWeightingPortfolioConstructionModel

Parameters
rebalancingDateRulesThe date rules used to define the next expected rebalance time in UTC
portfolioBiasSpecifies the bias of the portfolio (Short, Long/Short, Long)

Definition at line 41 of file EqualWeightingPortfolioConstructionModel.cs.

◆ EqualWeightingPortfolioConstructionModel() [2/6]

QuantConnect.Algorithm.Framework.Portfolio.EqualWeightingPortfolioConstructionModel.EqualWeightingPortfolioConstructionModel ( Func< DateTime, DateTime?>  rebalancingFunc,
PortfolioBias  portfolioBias = PortfolioBias.LongShort 
)

Initialize a new instance of EqualWeightingPortfolioConstructionModel

Parameters
rebalancingFuncFor a given algorithm UTC DateTime returns the next expected rebalance time or null if unknown, in which case the function will be called again in the next loop. Returning current time will trigger rebalance. If null will be ignored
portfolioBiasSpecifies the bias of the portfolio (Short, Long/Short, Long)

Definition at line 54 of file EqualWeightingPortfolioConstructionModel.cs.

◆ EqualWeightingPortfolioConstructionModel() [3/6]

QuantConnect.Algorithm.Framework.Portfolio.EqualWeightingPortfolioConstructionModel.EqualWeightingPortfolioConstructionModel ( Func< DateTime, DateTime >  rebalancingFunc,
PortfolioBias  portfolioBias = PortfolioBias.LongShort 
)

Initialize a new instance of EqualWeightingPortfolioConstructionModel

Parameters
rebalancingFuncFor a given algorithm UTC DateTime returns the next expected rebalance UTC time. Returning current time will trigger rebalance. If null will be ignored
portfolioBiasSpecifies the bias of the portfolio (Short, Long/Short, Long)

Definition at line 67 of file EqualWeightingPortfolioConstructionModel.cs.

◆ EqualWeightingPortfolioConstructionModel() [4/6]

QuantConnect.Algorithm.Framework.Portfolio.EqualWeightingPortfolioConstructionModel.EqualWeightingPortfolioConstructionModel ( PyObject  rebalance,
PortfolioBias  portfolioBias = PortfolioBias.LongShort 
)

Initialize a new instance of EqualWeightingPortfolioConstructionModel

Parameters
rebalanceRebalancing func or if a date rule, timedelta will be converted into func. For a given algorithm UTC DateTime the func returns the next expected rebalance time or null if unknown, in which case the function will be called again in the next loop. Returning current time will trigger rebalance. If null will be ignored
portfolioBiasSpecifies the bias of the portfolio (Short, Long/Short, Long)

This is required since python net can not convert python methods into func nor resolve the correct constructor for the date rules parameter. For performance we prefer python algorithms using the C# implementation
