Market Open vs Market Close: When Do Saudi Traders Prefer to Trade?

US Market Hours in Saudi Arabia: Why Timing Shapes Every Trading Decision

The New York Stock Exchange and Nasdaq open at 9:30 AM Eastern Time and close at 4:00 PM Eastern Time. For Saudi investors, that translates to a regular trading session running from 4:30 PM to 11:00 PM Saudi Arabia Standard Time (SAST). Understanding which part of this session offers the best opportunities, the market open or the market close and why each behaves so differently, is essential knowledge for any active trader operating from the Kingdom.

Saudi Standard Time (GMT+3) is ahead of US Eastern Time by 7 hours all year round; there is no DST observed in Saudi Arabia, so the Saudi Offset will always remain constant. However, because the US changes between Standard Time and Daylight Save Time (March and November), Raseed will also automatically change all session displays one hour after these US transitions to reflect current Saudi market hours.

US Market Session Times in Saudi Arabia Standard Time: Complete Reference

The Market Open (4:30 PM SAST): Maximum Opportunity, Maximum Risk

The first 30 minutes after the US market opens 4:30 PM to 5:00 PM SAST are consistently the most volatile and highest-volume period of the entire trading day. Overnight news, pre-market earnings, economic data released at 8:30 AM ET (3:30 PM SAST), and accumulated orders from millions of investors all flood the market simultaneously at the opening bell.

This creates an environment that is simultaneously the most opportunity-rich and most dangerous for traders. Bid-ask spreads are widest in the first few minutes, meaning the implicit cost of entering a trade is highest. Price gaps, where a stock opens significantly above or below its previous close are common and can move in either direction rapidly.

Why some Saudi traders prefer the open: The opening 30–60 minutes contain more price movement than any other equivalent period of the day. For momentum traders looking to capitalize on overnight news, earnings reactions, or sector moves triggered by pre-market data, the opening window is irreplaceable. A stock that reports strong earnings after the previous day's close will often see its sharpest price move in the first 30 minutes of the new session.

Why others avoid the first 15 minutes: Many experienced traders, including a significant proportion of active Saudi investors, deliberately avoid the very first 5–15 minutes of the session. During this period, price discovery is still in progress and false moves where price appears to be breaking out in one direction before rapidly reversing are most common. Waiting for the opening volatility to settle before entering improves trade quality meaningfully.

The Market Close and 'Power Hour' (9:30 PM – 11:00 PM SAST): Directional Conviction

'Power Hour,' which takes place from 2:30 PM to 4:00 PM ET (9:30 PM to 11:00 PM in Saudi Arabia), is the last 90 minutes of the regular trading session in the US. During this time, volume increases significantly because institutional investors, mutual funds and index funds place their last orders of the day, while retail traders are closing out positions prior to the official close.

Power Hour is characterised by strong directional moves. Stocks that have been trending throughout the session often accelerate toward the close as committed buyers or sellers complete their activity. The moves tend to be cleaner and more sustained than the choppy opening, making this period popular among Saudi traders who prefer trading in the evening hours.

Why many Saudi traders prefer the close window: For the GCC time zone, the market close falls in the late evening between 9:30 PM and 11:00 PM SAST. This is a natural time for Saudi investors to engage actively, with the day's obligations complete and full attention available for the market. The lower relative volatility (compared to the opening) and the cleaner directional signals of Power Hour suit a more measured, deliberate trading style. Many Saudi investors find that their best-quality trades occur in this window.

After-Hours Trading: The Advantage Only Available on Raseed

For Saudi and GCC investors, after-hours trading represents a fundamentally different opportunity. Once the regular session closes at 11:00 PM SAST, the most market-moving events begin: quarterly earnings from major companies like Apple, Microsoft, Nvidia, Amazon, and Meta are almost always released between 11:00 PM and 1:00 AM SAST.

The Mid-Session Window (5:30 PM – 9:30 PM SAST): Patience and Trend Trading

The middle of the trading day from approximately one hour after open to one hour before close is characterised by lower volatility, narrower spreads, and cleaner trend continuation. This is the period when short-term trends established at the open either sustain or fail, and when intraday support and resistance levels become most meaningful.

If you're a trader in Saudi Arabia that practices on longer timeframes or actively trades on the first hour of trading, you'll get the best returns from trading in the mid-session timeframes. The reason for this has to do with the overall direction the stock has established in the initial hour and whether it will stay consistent. The mid-session timeframe allows you to enter an established trend in the lower risk timeframe versus chasing the momentum of the stock in the first hour.
