The Rooster trading session aligns with standard U.S. equity market hours, opening at 9:30 a.m. Eastern Time and closing at 4:00 p.m. Eastern Time on weekdays. Pre-market trading typically starts at 4:00 a.m. ET, and after-hours trading runs until 8:00 p.m. ET, though liquidity is lower outside the core session.

Rooster pre-market and after-hours sessions are considered secondary trading hours and carry different price dynamics than the core session. Orders during these windows may be executed on a principal or agency basis depending on the broker and venue, and price slippage can be wider due to lower volume. The primary Rooster session remains the reference point for official open, close, and volume data used in most financial reports and benchmarks.
