Open: 9:30 AM Eastern Time (ET)
Close: 4:00 PM Eastern Time (ET)
Duration: 6.5 hours per trading day
Days: Monday - Friday (except holidays)
This is when most trading happens.
Highest liquidity (most buyers and sellers)
Tightest bid-ask spreads

Safest time for beginners to trade
Converting to Your Time Zone
If you're not in Eastern Time:
Eastern (ET)
9:30 AM
4:00 PM

Hawaii (HT)

Example:
You're in California (Pacific Time)
Market opens at 6:30 AM your time
Market closes at 1:00 PM your time
You can trade stocks between 6:30 AM - 1:00 PM PT
Why These Hours?
Historical reasons:
Aligned with business hours on East Coast (financial center)
Allows time for news digestion before open
Gives institutions time to process orders after close
Modern reality:
Most investors don't trade during all 6.5 hours
Many people trade in first 30 minutes (9:30-10:00 AM ET) = highest volume
Last 30 minutes (3:30-4:00 PM ET) = second highest volume ("power hour")
Middle of day (11 AM - 3 PM ET) = slower, less volatile
Pre-Market Trading
What Is Pre-Market?
Pre-Market Hours:
Start: 4:00 AM Eastern Time (ET)
End: 9:30 AM Eastern Time (ET)
Duration: 5.5 hours before regular market opens
What happens:
Some traders and institutions trade before market officially opens
Limited number of participants
Lower volume than regular hours
News and earnings often released during pre-market
Who Trades Pre-Market?
Typically:
Professional traders
Hedge funds and institutions
Day traders reacting to overnight news
Earnings traders (companies announce before market opens)
Not typically:
Long-term investors
Complete beginners
Casual investors
Pre-Market Characteristics
Lower liquidity:
Fewer buyers and sellers
Harder to find someone to trade with
Larger price swings on small volume
Wider spreads:
Bid-ask spread can be 5-10x wider than regular hours
Example: Regular hours $0.02 spread → Pre-market $0.20 spread
You pay significantly more buying, get significantly less selling
More volatility:
Prices can swing wildly on low volume
100-share order might move stock 1%
Not representative of where stock will trade during regular hours
Reacts to overnight news:
Earnings announcements (many companies report before market open)
International market movements (Europe, Asia)
Breaking news overnight
Federal Reserve announcements
Pre-Market Risks for Beginners
Risk #1: Fake Prices
What happens:
Pre-market: Stock shows $105
You place market order thinking that's the price
Regular market opens at 9:30 AM at $100
Your order fills at $100
You were misled by pre-market price
Risk #2: Wide Spreads Cost You Money
Example:
Regular hours:
Bid: $99.98 / Ask: $100.00
Spread: $0.02 (0.02%)
Pre-market:
Bid: $99.50 / Ask: $100.50
Spread: $1.00 (1%)
If you buy in pre-market:
Pay $100.50 (the ask)
Immediately worth $99.50 (the bid)
Instant 1% loss just from spread!
Risk #3: Low Volume = Price Manipulation
What happens:
Only 500 shares traded in pre-market
Stock shows as "up 10%"
Looks like strong momentum
Regular market opens, floods with volume
Price returns to normal
Pre-market move was meaningless
When to Trade Pre-Market (Advanced Only)
Only trade pre-market if:
✅ You're an experienced trader
✅ You understand extended hours risks
✅ There's legitimate catalyst (earnings, FDA approval, etc.)
✅ You use limit orders (never market orders)
✅ You accept wider spreads and volatility
Beginners: Skip pre-market trading entirely.

After-Hours Trading
What Is After-Hours?
After-Hours Trading:
Start: 4:00 PM Eastern Time (ET) (right when regular market closes)
End: 8:00 PM Eastern Time (ET)
Duration: 4 hours after regular market close
What happens:
Continued trading after regular hours close
Many companies release earnings after market closes (4:00-4:30 PM)
Allows reaction to late-breaking news
Similar characteristics to pre-market (low volume, wide spreads)
After-Hours Characteristics
Similar to pre-market:
Lower liquidity
Wider bid-ask spreads
More volatility
Not representative of next day's opening price
Common catalysts:
Earnings announcements (many companies report after 4 PM)
Breaking news after business hours
Federal Reserve announcements (sometimes 2 PM, affects after-hours)
International developments
After-Hours Risks
Same risks as pre-market:
Wide spreads cost you money
Low volume = big price swings
Prices not representative
Easy to overpay or get bad execution
Additional risk: Earnings volatility
Example:
Apple announces earnings at 4:05 PM (after market close)
Regular market closed at $175.50
Earnings miss expectations
After-hours: Stock drops to $165 on low volume (down 6%)
Panic selling in after-hours
Next morning (9:30 AM): Stock opens at $170 (recovered 50% of drop)
After-hours overreacted
If you sold in after-hours at $165, you got worst price. Better to wait for regular hours at $170.
When to Use After-Hours (Advanced)
Only trade after-hours if:
✅ You're experienced
✅ Reacting to earnings on position you own
✅ Using limit orders only
✅ Accept wide spreads
✅ Understand prices may be temporary
Beginners: Wait for regular market hours the next day.
Extended Hours Trading: Complete Timeline
Full Trading Day Timeline (Eastern Time):
Best Times to Trade (For Beginners)
The Safest Window: 10:00 AM - 3:30 PM ET
Why this is best for beginners:
✅ Tight spreads (lowest cost)
✅ Good liquidity (easy to buy/sell)
✅ Less volatility (calmer price movements)
✅ Opening chaos has settled
✅ Closing rush hasn't started
Recommended for:
Long-term investors
First-time buyers
Anyone buying index ETFs
Investors who want fair prices
Avoid: First 30 Minutes (9:30-10:00 AM ET)
Why beginners should avoid:
Extreme volatility (prices swing wildly)
Professionals dominate this time
Algorithms and high-frequency traders active
Hard to get good price
Easy to get caught in fake moves
What happens at open:
Overnight news gets digested
Orders built up overnight all execute at once
Huge volume spike
Prices can swing 2-5% in minutes
Then often revert back
Example:
Stock closed yesterday at $100
Overnight news: slightly positive
9:30 AM open: Stock gaps up to $103 (3% jump)
Beginners see "momentum" and buy at $103
By 10:00 AM: Stock settles back to $101
Beginners overpaid by $2/share (2%)
Better strategy:
Wait 30 minutes for dust to settle
See where price stabilizes
Make more informed decision
Avoid: Last 30 Minutes (3:30-4:00 PM ET)
Why beginners should avoid:
"Power Hour" = high volume and volatility
Institutional rebalancing
Day traders closing positions
Prices can swing significantly
What happens at close:
Fund managers adjust portfolios
Day traders must close positions (can't hold overnight)
Algorithms maximize volume
Price swings can be dramatic
For beginners:
Avoid trading 3:30-4:00 PM
If you must, use limit orders
Don't chase price movements

How to Check If Market Is Open
Quick ways to check:
1. Google Search:
Search "is stock market open today"
Google shows current status
2. Broker Apps:
Most show countdown to open/close
"Market opens in X hours"
3. Financial News Sites:
CNBC, Bloomberg, MarketWatch show current status
Display market hours prominently
4. NYSE/NASDAQ Websites:
Official calendars of trading days
Weekend Trading (Crypto vs Stocks)
Stocks: Weekends = Closed
U.S. stock market:
❌ Closed Saturdays and Sundays
❌ No trading Friday 8 PM - Monday 4 AM
❌ Cannot buy or sell stocks on weekends
What you can do on weekends:
✅ Research stocks
✅ Plan your trades for Monday
✅ Paper trade on Ape AI
✅ Read earnings reports
✅ Set limit orders for Monday open (won't execute until market opens)
Weekend news:
News can break on weekends
Affects Monday's opening price
Creates "gap" (stock opens higher/lower than Friday close)
Crypto: 24/7/365
Cryptocurrency markets (Bitcoin, Ethereum, etc.):
✅ Open 24 hours a day
✅ Open 7 days a week
✅ Open 365 days a year (including holidays)
Never closes
Key difference:
Stocks = business days only
Crypto = every day, all day
Some brokers (like Robinhood) allow crypto trading 24/7 but stocks only during market hours.
International Markets
When Other Major Markets Are Open
If you trade international stocks through ADRs or international brokers:
London Stock Exchange (LSE):
3:00 AM - 11:30 AM Eastern Time
Overlaps with early U.S. pre-market and morning
Hong Kong Stock Exchange (HKEX):
9:30 PM - 4:00 AM Eastern Time (next day)
Trades while U.S. sleeps
Tokyo Stock Exchange (TSE):
8:00 PM - 2:30 AM Eastern Time (next day)
Trades while U.S. sleeps
Frankfurt Stock Exchange (FRA):
3:00 AM - 11:30 AM Eastern Time
Overlaps with U.S. pre-market
Why this matters:
International news affects U.S. stocks
If European markets drop 3%, U.S. market often opens lower
Gives preview of sentiment before U.S. open
Common Questions
"Can I place an order when the market is closed?"
Yes, but it won't execute until market opens.
What happens:
You place limit order Saturday at noon
Order sits in queue
Monday 9:30 AM: Market opens, your order becomes active
Executes if price reaches your limit
Risk:
Stock might gap (open much higher/lower than Friday close)
Your limit order might fill at worse price than expected
Or might not fill at all if gap went past your limit
"What if I try to place a market order after hours?"
Depends on broker:
If extended hours NOT enabled:
Order queues for next market open
Executes at 9:30 AM (or next trading day if weekend)
If extended hours enabled:
Order executes in after-hours market
You'll pay wider spread
Get after-hours price
Most brokers default to NOT allowing extended hours unless you specifically enable it.
"Why don't they keep the market open 24/7 like crypto?"
Historical reasons:
Stock market existed before computers
Needed time to process paper trades
Participants needed rest
Modern reasons:
Circuit breakers and system maintenance happen overnight
Regulators can review day's activity
Prevents non-stop volatility and exhaustion
Allows fair playing field (everyone gets rest)
Proposal for 24/7 stocks:
Some have proposed it
SEC has not approved
Likely won't happen soon
"Can I cancel an order placed when market is closed?"
Yes!
You can cancel any limit order anytime before it fills
Weekend order can be cancelled Sunday night before Monday open
Go to "Open Orders" and click "Cancel"

You set GTC limit order at $175.00
Monday 9:30 AM: If Apple hits $175.00, you're filled
