What time does the stock market open in Colorado
What time does the stock market open in Colorado
Short description: This article answers what time does the stock market open in Colorado by mapping U.S. equities exchange hours (NYSE and NASDAQ) to Colorado local time (Mountain Time). It covers regular session hours, pre-market and after-hours conversions, broker and exchange differences, holiday/early-close rules, practical trading guidance for Colorado-based traders, and contrasts with 24/7 cryptocurrency markets.
截至 2025-12-31，据 NYSE Hours & Calendars page 报道，U.S. exchanges maintain a consistent regular trading session of 9:30 AM–4:00 PM Eastern Time, which directly converts to Mountain Time for Colorado residents as described below.
Quick note for readers: this page explains what time does the stock market open in Colorado, what extended hours look like in Mountain Time, and why you should check your broker for exact pre-/post-market windows. If you trade crypto, Bitget and Bitget Wallet offer 24/7 markets and dedicated tools tailored for around-the-clock trading.
Quick answer (summary)
- Regular U.S. equities session (NYSE/NASDAQ) opens at 7:30 AM Mountain Time (Colorado local time) and closes at 2:00 PM Mountain Time on standard trading days.
- Extended hours (pre-market and after-hours) vary by exchange and broker but commonly appear roughly as 5:00 AM–7:30 AM MT for pre-market and about 2:00 PM–6:00 PM MT for after-hours at many retail brokers.
- Cryptocurrency markets (including services on Bitget) trade 24/7, so their availability differs from U.S. equities.
Time zones and Colorado
Colorado time zone (MST/MDT)
Colorado uses Mountain Time. That means:
- Mountain Standard Time (MST) is UTC−7. MST applies during the late fall and winter months.
- Mountain Daylight Time (MDT) is UTC−6. MDT applies during daylight saving time in spring and summer.
When Denver and the rest of Colorado switch clocks for daylight saving, the label changes from MST to MDT but the local wall-clock times shift by one hour in tandem with other U.S. regions that observe DST.
Relationship to Eastern Time (New York)
Colorado is two hours behind Eastern Time (ET) year-round for practical clock conversions. Because both Colorado (Mountain Time) and New York (Eastern Time) observe daylight saving time, the two-hour difference remains the same whether DST is in effect or not. That means:
- New York open at 9:30 AM ET = Colorado open at 7:30 AM local time.
- New York close at 4:00 PM ET = Colorado close at 2:00 PM local time.
This consistent two-hour offset makes converting U.S. equity hours into Colorado time straightforward for everyday scheduling.
Regular U.S. stock market hours converted to Colorado time
Short description: The core NYSE/NASDAQ regular trading session runs 9:30 AM–4:00 PM Eastern Time. Converted for Colorado, that becomes 7:30 AM–2:00 PM Mountain Time. Daylight saving time does not change the local-to-local conversion because both zones shift together.
Regular session (core trading)
- NYSE/NASDAQ regular trading session: 9:30 AM–4:00 PM Eastern Time.
- Colorado (Mountain Time): 7:30 AM–2:00 PM local time.
Put simply, Colorado traders see the market open at 7:30 AM and close at 2:00 PM on normal trading days.
Examples (dates/times)
-
Example 1 (summer / DST): When NYSE opens at 9:30 AM ET on July 1, that corresponds to 7:30 AM MDT in Colorado. The market closes at 4:00 PM ET → 2:00 PM MDT.
-
Example 2 (winter / standard time): When NYSE opens at 9:30 AM ET on December 1, that corresponds to 7:30 AM MST in Colorado. The market closes at 4:00 PM ET → 2:00 PM MST.
Both examples illustrate the constant two-hour difference: the answer to "what time does the stock market open in Colorado" for the regular session remains 7:30 AM local time year-round.
Pre-market and after-hours (extended-hours) in Colorado
Short description: Extended-hours trading exists before and after the regular session; actual windows vary by exchange and broker. When converted to Mountain Time, pre-market sessions occur early in the morning before 7:30 AM, and after-hours run into the evening after 2:00 PM local time.
Typical pre-market times (Mountain Time)
- Many brokers and ECN platforms provide pre-market trading that, when converted to Mountain Time for Colorado residents, commonly starts around 5:00 AM MT and runs up to the regular open at 7:30 AM MT.
- Some brokerages offer even earlier electronic order entry or limited ECN access that can begin earlier (e.g., 4:00 AM–5:00 AM MT depending on the provider). Availability depends on the broker and the routing networks they use.
Typical after-hours times (Mountain Time)
- Retail broker after-hours (extended) trading is commonly available roughly from 2:00 PM MT (market close) through about 6:00 PM MT, which corresponds to 4:00 PM–8:00 PM ET.
- Institutional or advanced ECN access can extend beyond those windows, but many retail platforms cap after-hours trading earlier.
Broker and exchange differences
- Extended-hours rules differ by exchange (NYSE vs. NASDAQ ECNs) and by broker. Some platforms let you trade a wide range of tickers in extended hours; others restrict eligibility to certain securities or order types.
- Order types: many brokers only accept limit orders during extended hours and reject market orders to prevent unexpected executions in low-liquidity conditions.
- Execution and routing: price improvement, matching engines, and ECN rules vary. Trades that occur in extended hours may not reflect the primary exchange's consolidated last sale until after markets reopen.
Because of these differences, Colorado-based traders should verify their broker’s published extended-hours windows and restrictions. Examples of brokers that publish clear extended-hours schedules include thinkorswim, E*TRADE, Fidelity, and Cash App (check each provider for Mountain Time conversions and exact minutes of availability).
Holidays and early-closing days (Colorado local time)
Short description: U.S. exchange holidays follow the NYSE/NASDAQ calendar. Colorado traders should expect full-day closures on major federal holidays and occasional early-closes where the regular session ends earlier than 2:00 PM MT.
Common full-day closures
The NYSE and NASDAQ typically close for the following major holidays. On these days the markets are closed (no regular session):
- New Year’s Day
- Martin Luther King Jr. Day
- Presidents’ Day (Washington’s Birthday)
- Good Friday
- Memorial Day
- Juneteenth
- Independence Day (Fourth of July)
- Labor Day
- Thanksgiving Day
- Christmas Day
When a holiday falls on a weekend, exchanges may observe the holiday on a nearby weekday; check the current-year calendar for exact observance dates. Because the markets are closed, conversion to Colorado time is not applicable those days.
Common early-closes (half-days)
Exchanges commonly schedule early-closing sessions on specific days. Typical early-closes include:
- Day after Thanksgiving: early close in the U.S. usually at 1:00 PM Eastern Time → 11:00 AM Mountain Time.
- Christmas Eve (when it falls on a weekday): often an early close around 1:00 PM ET → 11:00 AM MT, though the schedule can vary by year.
- Sometimes the day before Independence Day may have an early close if July 4th falls on a weekday or adjacent to a weekend; check the current-year schedule.
Caution: exact early-close times and which days are shortened can change year by year. Always verify the NYSE/NASDAQ holiday calendar for the specific year you plan to trade.
Practical notes for Colorado-based traders
This section lists practical, actionable considerations for anyone in Colorado asking "what time does the stock market open in Colorado" and planning to trade.
Order types and execution limitations in extended hours
- Many brokers restrict extended-hours trading to limit orders to avoid the risk of a market order executing at a far worse price in low-liquidity conditions.
- Check whether your broker accepts stop orders or trailing stops during extended hours — most do not, or they convert them to regular-session orders.
- Odd-lot trades, certain option-linked securities, and some OTC listings may not be available in extended sessions.
Liquidity, spreads, and risks
- Extended-hours sessions typically have lower liquidity and wider bid/ask spreads than the regular session. That increases transaction cost and the risk of partial fills.
- Prices in pre-market and after-hours can gap significantly when markets open or close, especially around earnings releases or major economic news.
- Price discovery during extended hours can be more volatile; institutional trades or news-driven orders can move prices rapidly with less depth to absorb them.
Broker-specific hours & tools
- Check your broker’s published hours. Examples of platforms that publish Mountain Time conversions and extended-hours rules include thinkorswim, E*TRADE, Fidelity, and Cash App. Each platform defines pre-market/after-hours windows, eligible securities, and supported order types.
- Use broker-provided tools (extended-hours filters, historical extended-hours book data, and real-time quotes) to better plan executions in non-regular sessions.
- If you primarily trade outside the regular session, test order execution on small sizes first to verify how your broker routes and fills extended-hours orders.
Practical tip: mark your calendar for 7:30 AM MT as the regular opening bell and 2:00 PM MT as the regular close; then consult your broker for pre/post-session windows if you trade outside those times.
How this differs from cryptocurrency markets
Short description: Unlike U.S. stock exchanges, most cryptocurrency markets trade 24/7/365. If you trade crypto on Bitget or use the Bitget Wallet, markets are available at all hours (subject to platform maintenance windows).
- Crypto vs. stocks: U.S. equities have scheduled hours and holidays; cryptocurrency markets run continuously.
- For Colorado traders, the question "what time does the stock market open in Colorado" does not apply to crypto. Instead, crypto platforms like Bitget provide round-the-clock order books and tools for continuous trading in Mountain Time.
- Exchange maintenance windows can temporarily pause trading on any platform (crypto or equities) — Bitget posts maintenance notices in advance on platform dashboards.
Frequently asked questions (FAQ)
Q: Does daylight saving time change the converted opening hour in Colorado?
A: No. Because both Eastern Time (New York) and Mountain Time (Colorado) observe daylight saving time, the two-hour difference holds year-round. The market still opens at 7:30 AM local time in Colorado when New York’s market opens at 9:30 AM ET.
Q: Can I trade after-hours on all stocks?
A: No. Extended-hours trading availability depends on exchange rules and your broker’s policy. Some securities are excluded from extended sessions and certain order types (like market orders) may be disallowed.
Q: What time does the stock market open in Colorado on holidays?
A: On major exchange holidays the market is closed, so there is no open time. For days with early-closes, the regular session often ends earlier (common early-close is 1:00 PM ET → 11:00 AM MT), but you should verify the current-year NYSE/NASDAQ calendar.
Q: Are pre-market and after-hours prices considered official?
A: Trades in extended hours are real trades but may not be reflected immediately in consolidated official prints and can be subject to different rules; regular-session prints are the primary reference.
Q: Where can I find the exact hours that apply to my account?
A: Check your broker’s official trading hours page or platform documentation. Brokers like thinkorswim, E*TRADE, Fidelity, and Cash App list pre-market and after-hours windows and eligible symbols. For crypto trading, consult Bitget’s platform notices and Bitget Wallet guidance.
