HistoricalAccountSelector

Account selector for NAV queries. Exactly one selector mode is valid: either LiveAccountId or the pair (BrokerType, BrokerAccountId). A live-account selector returns at most one series. A broker selector can return several live-account series when the same broker account id maps to more than one internal account row over time.

Field	Type	Required	Nullable	Default	Description
LiveAccountId	int	No	Yes		Internal live account id.
BrokerType	BrokerType	No	Yes		Broker/provider backing the account. Required when selecting by broker account id.
BrokerAccountId	str	No	Yes		Provider-specific broker account id. Required when selecting by broker account id.
