Not all market hours are created equal. The time you choose to trade can significantly impact your profitability. This guide breaks down the best and worst times to day trade, helping you focus your energy when opportunities are highest.
US Stock Market Hours
The US stock market (NYSE and NASDAQ) has specific trading sessions:
- Pre-market: 4:00 AM - 9:30 AM ET
- Regular hours: 9:30 AM - 4:00 PM ET
- After-hours: 4:00 PM - 8:00 PM ET
Most day traders focus on regular market hours when volume and liquidity are highest. Pre-market and after-hours trading have wider spreads and lower volume, making them riskier.
The Best Times to Day Trade
1. Market Open (9:30 AM - 10:30 AM ET)
The first hour of trading is often the most volatile and active period of the day. This is when:
- Overnight news and earnings get priced in
- Gaps from after-hours trading create opportunities
- Volume is highest, providing best liquidity
- Price moves are largest and fastest
Pro tip: Many experienced day traders make most of their profits in the first 1-2 hours. They then stop trading or significantly reduce size for the rest of the day.
2. Power Hour (3:00 PM - 4:00 PM ET)
The last hour of trading is called "power hour" because:
- Institutional traders make end-of-day adjustments
- Volume picks up as traders close positions
- Trends often accelerate into the close
- Day traders must close positions, creating movement
Power hour can be especially volatile on Fridays when weekly options expire.
3. Pre-Market Movers (8:00 AM - 9:30 AM ET)
While pre-market trading has lower volume, this time is valuable for:
- Identifying stocks with news catalysts
- Planning your trading day
- Watching how gappers are trading
- Setting up your watchlist
Times to Avoid Trading
The Lunch Hour Lull (11:30 AM - 1:30 PM ET)
Midday is typically the slowest period. During this time:
- Volume drops significantly
- Price action becomes choppy and directionless
- Spreads can widen
- False breakouts are more common
Many day traders take a break during lunch, using the time to review morning trades, eat, and prepare for the afternoon session.
Warning: Trading during low-volume periods often leads to overtrading, frustration, and giving back morning profits. Discipline means knowing when NOT to trade.
Best Days of the Week
Tuesday, Wednesday, Thursday
Midweek days typically offer the best trading conditions:
- Most earnings reports come out Tuesday-Thursday
- Economic data releases are spread throughout
- Full institutional participation
- Consistent volume patterns
Monday
Mondays can be tricky:
- Weekend news creates gaps
- Traders need time to assess new information
- Volume can be lower early
- Best trading often happens after 10:00 AM
Friday
Fridays have unique characteristics:
- Weekly options expiration creates volatility
- Some traders close positions before the weekend
- Volume often decreases after lunch
- Major trend moves can happen as traders adjust positions
Trading Around Economic Events
Major economic events can create significant volatility:
- FOMC announcements: Usually 2:00 PM ET, expect extreme volatility
- Jobs report: First Friday of each month at 8:30 AM ET
- CPI/Inflation data: Creates market-wide moves
- GDP releases: Quarterly economic data
Some traders specifically trade these events. Others avoid them entirely because of unpredictable moves. Know your strategy and risk tolerance.
Creating Your Trading Schedule
Here is a sample schedule for day traders:

- 9:30-11:30 AM: Active trading
- 11:30 AM-1:30 PM: Break, review
- 1:30-4:00 PM: Selective trading

Time Zone Considerations
If you are not on the East Coast:
- Pacific Time: Market opens at 6:30 AM, closes at 1:00 PM
- Mountain Time: Market opens at 7:30 AM, closes at 2:00 PM

West Coast traders have an advantage for morning trading but must wake up early. East Coast traders can trade morning and afternoon sessions more comfortably.
