If you follow the American stocks, the first thing you need to know is exactly when the US market opens. Many new traders don’t pay attention to the timings, but the truth is that knowing the session times, holidays, and important events makes a big difference between successful trading and unnecessary losses.

Over time, I’ve noticed that the US market is not just one number; there are many details that, if understood correctly, you can benefit from. When does the US market officially open? From Monday to Friday at 9:30 AM New York time, and the session continues until 4:00 PM. These hours are the most liquid and safest for trading.

But it doesn’t end here. There is a pre-market session from 4:00 AM to 9:30 AM, and an after-hours session from 4:00 PM to 8:00 PM. These periods have movement but less liquidity, and wider price gaps, so you need to be cautious.

Regarding the timing in Arab countries, if you are in Saudi Arabia or the UAE, the official session starts from 5:30 PM until midnight. In Egypt, roughly from 4:30 PM to 11:00 PM. Each country has a different time difference, but the idea is the same.

One of the most important things that affect the market is official holidays. From 2026 to 2028, there are specific holidays with no trading, such as New Year’s, US Independence Day, Thanksgiving, and Christmas. If you don’t pay attention to these dates, you might lose money waiting for orders that have no liquidity.

There are also days with early close at 1:00 PM New York time, like the day after Thanksgiving. These days, movement is weak and spreads are wider, so I don’t recommend trading on them.

Major economic events change the market direction at lightning speed. FOMC meetings are very important because they determine interest rate policy. The quarterly earnings season is also crucial, especially for big companies like Apple, Microsoft, Tesla, and Amazon. If one of these companies announces disappointing results, it can drag the entire market down with it.

Regarding the best trading times, the first hour after opening from 9:30 to 10:30 AM New York time is usually the most active. The movement is strong, and the market absorbs news that appeared before opening. But the movement can be fast and sudden, so it’s not always suitable for beginners.

Mid-session is usually calmer, especially if there are no important data or news. The last hour before close from 3:00 to 4:00 PM New York time is very important because institutions may be rebalancing their positions, and clear opportunities may appear.

I’ve noticed that knowing when the US market opens isn’t enough; you also need to understand what moves stocks during the session. Economic data like inflation and employment figures change the market quickly. Federal Reserve officials’ statements also have a very big impact. Geopolitical news can either increase or decrease risk appetite in an instant.

Pre- and post-opening periods carry higher risks because liquidity is lower and volatility is greater. Many companies announce their results after market close, and the next day may open with a big price gap. If you only follow the market from 9:30 to 4:00, you might be surprised by a big move that actually started outside the official session hours.

Regarding strategies, the best one for beginners is momentum trading right after the open. If you see a stock moving 2% or more with high trading volume in the first 15 minutes, that’s a strong signal. But you need to be cautious because the movement can reverse quickly.

Another strategy is breakout trading. When a stock breaks a key level like the high of the first 15 minutes or a clear daily resistance, with high volume, that’s a good opportunity. But if the breakout happens without volume, don’t trust it.

Fast retracement trading is also effective. After a sharp and exaggerated move, wait for a reversal signal from a clear level. Trading based on news is very important, but you must focus on how the price responds to the news, not just the news itself.

My advice: don’t enter a trade just because the US market opens. Wait a bit until the initial movement calms down and the trend becomes clearer. Review the economic calendar before the session to avoid entering before data releases that could change the market entirely. Check company earnings dates, as a stock can move strongly. Use stop-losses seriously, especially in the first and last hours. And most importantly, start with a demo account or small size until you test your strategy.

The truth is, understanding when the US market opens, the trading hours, holidays, and key events isn’t optional; it’s essential for any serious trader. All these details help you read the market better and handle opportunities more intelligently. And most importantly, choose a trading tool that suits you and gives you the flexibility you need, always focusing on risk management and discipline in executing trades.
