Pre-Market(redirected from Pre Market Trading)
Describing trading that occurs on a security before an exchange opens for the day. Pre-market trading is often less liquid than regular trading because participation by market makers is voluntary, whereas market makers are required to serve as a counterparty for a security during trading hours. However, pre-market trading can give some indication on the likely direction of the security's price movement over the course of the trading day. See also: After-hours trading.
