Function: periodKey()

periodKey(t, freq): string

Defined in: tactical/from-spec.ts:80

Returns a stable string key that identifies the rebalance period containing date t for the given freq. Two dates that map to the same key belong to the same period and therefore produce the same rebalance decision. Used internally by isRebalanceDay to detect period boundaries.

Parameters

Parameter	Type	Description
t	Date	The date to classify.
freq	RebalanceFrequency	Rebalance cadence (see RebalanceFrequency).

Returns

string

A compact string such as '2024-3' (monthly), '2024-W14' (weekly), or '2024-1' (quarterly Q2).
