Ever wondered if the Tokyo Stock Exchange is still open while you're having breakfast in Warsaw?
Market Clock Hub shows live trading hours for major global exchanges and commodities — all in your local timezone. It comes with five popular exchanges (NYSE, LSE, XETRA, HKEX Hong Kong, TSE Tokyo) and four commodities (WTI Crude Oil, Gold, Copper, Wheat) as ready-made examples, but you can add any market you want: GPW Warsaw, BSE India, SSE Shanghai, your local bourse — whatever matters to you.
No spreadsheets, no signup. Just open the page and see what's open right now! 📈
Here are the regular session hours for the five built-in exchanges, in their local timezones. For your own timezone, use the live clocks above — they convert everything automatically.
| Exchange | City | Local Session | Timezone |
|---|---|---|---|
| NYSE | New York | 09:30 – 16:00 | EST / EDT |
| LSE | London | 08:00 – 16:30 | GMT / BST |
| XETRA | Frankfurt | 09:00 – 17:30 | CET / CEST |
| HKEX | Hong Kong | 09:30 – 12:00 13:00 – 16:00 | HKT |
| TSE Tokyo | Tokyo | 09:00 – 15:30 | JST |
These are regular session hours only — pre-market and after-hours sessions vary by exchange and are shown live in the dashboard above.
Trading doesn't sleep — but the best opportunities cluster around overlaps: windows when two major exchanges are open at the same time.
The biggest one is the London–New York overlap, running roughly 13:00–16:00 GMT (8:00–11:00 EST). That's when both European and US traders are at their desks, spreads tighten, and volume spikes — which is why EUR/USD, GBP/USD and US indices move the most during these three hours. The Overlap panel shows you exactly where you are in the 24-hour cycle — with your local time on the right, so you never have to convert anything in your head.
Some dates move markets more than others — and missing them can cost you.
OPEX (options expiration) happens every third Friday, with the quarterly triple witching in March, June, September and December bringing the heaviest volume of the quarter.
FOMC meetings — eight per year — decide interest rates and routinely trigger sharp moves in the dollar, gold and indices.
On top of that, weekly expirations across FX, commodities, indices, agriculture and crypto quietly roll over every few days. This panel pulls all of them into one place, with live countdowns in your local time — so you always know what's coming, before it hits.
Every exchange card has a small folded corner in the bottom-right. Click it, and the card flips over to reveal the index composition — the top 20 constituents of the exchange's flagship index, ranked by weight (largest first). You'll see the ticker, the company name, the weight as a percentage, and a proportional bar so you can see at a glance which names dominate the index.
For example, flip the HKEX Hong Kong card and you'll see the Hang Seng Index — 20 largest and most liquid companies on the Hong Kong Stock Exchange, from Tencent (8.00%) and Alibaba (7.50%) down to CK Hutchison (1.20%). This is exactly the data you need to understand why an index moves the way it does — a 2% move in a stock with 8% weight moves the index far more than a 2% move in one with 1% weight.
The flip works for all built-in exchanges (visible and hidden) and shows the index composition updated as of the date shown at the bottom of each card.
Not every market you trade is on the default list — and that's exactly the point.
Whether you follow GPW Warsaw, BSE India, the Shanghai Stock Exchange, B3 São Paulo, or a niche commodity like Natural Gas or Cocoa, you can add it in seconds: name it, set the trading sessions, pick a timezone, and it appears on your dashboard alongside the built-in markets.
Your layout, your watchlist, your rules. Everything is saved right in your browser, so there's no account to create, nothing to remember, and no data leaving your device.
Market Clock Hub is a passion project built by a self-taught financial markets enthusiast — not a corporation, not a team of developers, just one person who has spent years navigating the world of trading and always felt something was missing. Across countless platforms, forums and tools, one question kept coming back: when do markets actually move, and how do their sessions overlap? No tool answered it cleanly. So this one was built from scratch — a single dashboard that maps the time-based dependencies of every major market, in your own timezone. It's a work in progress, made by someone who is still learning, still trading, and still searching for an edge.
If it helps you find yours, it's done its job.
I do my best to keep the database as accurate and up-to-date as possible — but mistakes can happen. If you spot an error, just let me know at bullishbeareconomy@gmail.com.
Getting started takes about ten seconds — here's the short version:
Follow along for market hours updates, session overlap alerts and new feature releases:
Stock market trading hours vary by exchange. NYSE trades 9:30–16:00 EST, LSE 8:00–16:30 GMT, XETRA 9:00–17:30 CET, HKEX 9:30–12:00 and 13:00–16:00 HKT, and TSE Tokyo 9:00–15:30 JST. Market Clock Hub converts every session into your local timezone automatically, so you always know exactly when each exchange opens and closes in your time.
The New York Stock Exchange (NYSE) opens at 9:30 AM EST (Eastern Standard Time) and closes at 4:00 PM EST. In your local timezone, this depends on where you are — for example, 15:30 CET in Warsaw, 14:30 GMT in London, or 23:30 JST in Tokyo. Market Clock Hub shows the exact NYSE opening and closing times converted to your local clock in real time.
A market overlap occurs when two or more major exchanges are open simultaneously — typically creating the highest liquidity and volatility of the day. The London–New York overlap (13:00–16:00 GMT / 8:00–11:00 EST) is the most actively traded window globally, especially for EUR/USD, GBP/USD and US indices. During this window, both major financial centres are active, producing the tightest spreads, deepest order books and highest volume — widely considered the optimal session for intraday trading.
Pre-market trading happens before the regular session opens — for US stocks, between 4:00 AM and 9:30 AM EST. After-hours trading happens after the close, between 4:00 PM and 8:00 PM EST. Both sessions have lower liquidity and wider spreads than regular hours, but allow traders to react to overnight news and earnings releases. Market Clock Hub displays pre-market and post-market sessions for every major exchange.
EC stands for Early Close — a day when the exchange closes earlier than usual. For example, LSE closes at 12:30 on Christmas Eve and New Year's Eve, NYSE closes at 13:00 ET on the day after Thanksgiving and on Christmas Eve, and XETRA closes at 14:00 on 30 December. Market Clock Hub shows these shortened sessions automatically — the countdown timer, session progress bar and phase information all reflect the early close, and an orange EC badge appears next to the status.
OPEX (options expiration) is always on the third Friday of every month. Quarterly OPEX — also called triple witching — falls on the third Friday of March, June, September and December, and typically has the highest trading volume of the quarter. Triple witching is the simultaneous expiration of three types of contracts: stock index futures, stock index options, and stock options.
Trading on expiring contracts stops at the market close — 4:00 PM ET for US equities and index options. In your local time, this depends on where you are: 22:00 GMT+2 in Warsaw (summer) / 21:00 GMT+1 (winter), 21:00 GMT in London, or 05:00 JST in Tokyo (next day). Market Clock Hub shows the exact OPEX time in your timezone automatically in the OPEX panel above.
The Federal Open Market Committee (FOMC) meets eight times per year, roughly every six weeks. Rate decisions are announced on the second day of each two-day meeting at 2:00 PM EST, followed by a press conference at 2:30 PM EST. Market Clock Hub shows all upcoming FOMC meetings with live countdowns in your local timezone.

For example, flip the HKEX Hong Kong card to see the Hang Seng Index — 20 largest and most liquid companies on the Hong Kong Stock Exchange, from Tencent (8.00%) and Alibaba (7.50%) down to CK Hutchison (1.20%).

The flip works for all built-in exchanges — NYSE (S&P 500), LSE (FTSE 100), XETRA (DAX 40), TSE Tokyo (Nikkei 225), HKEX Hong Kong (Hang Seng), GPW Warsaw (WIG20, hidden by default), BSE India (Sensex), SSE Shanghai (SSE Composite), B3 São Paulo (Ibovespa), ASX Sydney (S&P/ASX 200) and JSE Johannesburg (FTSE/JSE Top 40).
