Lifecycle

The lifecycle channel reports each change to a market’s status. It costs token per market, and trades, bbo, and book include it. On an event: subject, it also covers markets that open later.

Live play and your orders

GOLIVE voids every resting order and turns taker fees on.
UNLIVE drains the book again and turns taker fees off.

Taker fees switch on at GOLIVE only for a market whose fee.charged is WHEN_LIVE. An ALWAYS market charges fees in every phase. See Trading fees. This is one market that goes live twice:

Phase	What happens
Pregame	Orders rest
`GOLIVE`	Orders voided, taker fees on
In play	Orders rest
`UNLIVE`	Book drained, taker fees off
`GOLIVE`	Orders voided, taker fees on

GOLIVE and UNLIVE repeat on a delay, a review, or a stoppage. Act on each transition as it arrives, and don’t assume a fixed number of them.
