Markets & trading
Pre-market trading occurs before an exchange's main regular session under specific venue and broker rules. Participation and liquidity are often lower than during normal hours.

A few stalls trade before the full market opens. Prices can form, but fewer participants and less stock make each order more influential.
Now put that into markets
Earnings and other news can produce pre-market quotes and trades. The regular opening auction may later combine a much larger set of orders.
Eligible order types, hours, venues and protections vary. Wider spreads, thinner depth and fragmented information can increase execution uncertainty.
Identify the exact session, time zone, venue coverage and volume. Do not treat one pre-market print as the regular market's settled view.
Indicative moves can reverse at the open, and many investors cannot access the same conditions. Historical measurement must use prices actually available under the stated rule.
