Member Function Documentation

TryGroup()

bool QuantConnect.Securities.Positions.IPositionGroupResolver.TryGroup	(	IReadOnlyCollection< IPosition >	newPositions,
		PositionGroupCollection	currentPositions,
		out IPositionGroup	group
	)

Attempts to group the specified positions into a new IPositionGroup using an appropriate IPositionGroupBuyingPowerModel for position groups created via this resolver.

Parameters

newPositions	The positions to be grouped
currentPositions	The currently grouped positions
group	The grouped positions when this resolver is able to, otherwise null

Returns

True if this resolver can group the specified positions, otherwise false

Implemented in QuantConnect.Securities.Positions.CompositePositionGroupResolver, and QuantConnect.Securities.Positions.SecurityPositionGroupResolver.

Here is the caller graph for this function:

Resolve()

PositionGroupCollection QuantConnect.Securities.Positions.IPositionGroupResolver.Resolve

(

PositionCollection

positions

)

Resolves the position groups that exist within the specified collection of positions.

Parameters

positions

The collection of positions

Returns

An enumerable of position groups

Implemented in QuantConnect.Securities.Positions.OptionStrategyPositionGroupResolver, QuantConnect.Securities.Positions.CompositePositionGroupResolver, and QuantConnect.Securities.Positions.SecurityPositionGroupResolver.

Here is the caller graph for this function:

GetImpactedGroups()

IEnumerable<IPositionGroup> QuantConnect.Securities.Positions.IPositionGroupResolver.GetImpactedGroups	(	PositionGroupCollection	groups,
		IReadOnlyCollection< IPosition >	positions
	)

Determines the position groups that would be evaluated for grouping of the specified positions were passed into the Resolve method.

This function allows us to determine a set of impacted groups and run the resolver on just those groups in order to support what-if analysis

Parameters

groups	The existing position groups
positions	The positions being changed

Returns

An enumerable containing the position groups that could be impacted by the specified position changes

Implemented in QuantConnect.Securities.Positions.OptionStrategyPositionGroupResolver, QuantConnect.Securities.Positions.CompositePositionGroupResolver, and QuantConnect.Securities.Positions.SecurityPositionGroupResolver.
