A new series gets a new identifier, USDC-cNGN-<DDMONYY>, and its own expiry.

future.last_trade_time is when the series stops trading. The top-level last_trade_timestamp on GET /v1/markets is something else: the time of the market’s most recent fill.

Trading hours

Both markets trade around the clock. A future stops at its last_trade_time, and the matcher pauses while the index is stale or the MarginEngine is paused.
