Pre-Market
Trading done before the regular market opens.

Investopedia Says:
Participation by market makers and ECNs is voluntary, so in pre-market trading there may be less liquidity than during normal hours of trading. If you are trading in pre-market or after-hours, you should always use a limit order.
