Four-Stage Process Before Market Open (09:00-09:30)

The pre-opening auction process on HKEX is divided into four phases. Investors should understand the rules for each stage:

Stage 1: Order Entry Period (09:00-09:15)

During this window, investors can input limit and market orders, which can be modified or canceled at any time. There is ample time to adjust strategies.

Stage 2: Pre-Opening Matching (09:15-09:20)

The exchange accepts buy and sell orders, but with restrictions: prices must be within the range of the highest bid and lowest ask recorded at 09:15. Orders entered in this phase cannot be canceled or modified.

Stage 3: Continuous Matching (09:20-09:22)

The system enters automatic matching mode. Investors cannot input, modify, or cancel orders. The exchange calculates a reference equilibrium price based on the submitted quotes and matches orders randomly at that price.

Stage 4: Pause Period (09:22-09:30)

All trading activities are suspended, awaiting the official market open.

Note: If a reference equilibrium price cannot be determined in the first three stages, automatic matching will not occur on that day’s opening. Investors should analyze market trends in advance and seek trading opportunities during the pre-opening phase.

After-Hours Reverse Process (16:00-16:10)

The closing process is the reverse of the opening, divided into four periods to determine the after-hours price:

Period 1: Calculate Reference Price (16:00-16:01)

Based on last-minute trading data during the continuous trading session, the exchange calculates and announces the after-hours reference price.

Period 2: Order Entry (16:01-16:06)

Investors can place new orders or modify/cancel existing ones. Quotes must be within ±5% of the reference price.

Period 3: No Cancellation (16:06-16:08)

Orders can only be placed; cancellations or modifications are not allowed.

Period 4: Random Closing (16:08-16:10)

Investors may input new orders but cannot cancel or modify existing ones. The exchange randomly closes the market within this two-minute window. It automatically determines the closing price as the price with the highest trading volume among all matching orders that meet the criteria.

Trader’s Note: The randomness of the closing process means the final transaction price can vary. Investors should complete all order adjustments before 16:06.

Half-Day Trading and Special Arrangements

On certain dates (such as Christmas Eve, New Year’s Eve, Lunar New Year’s Eve), HKEX implements half-day trading with the following rules:

• Morning pre-market auction: 09:00-09:30
• Morning trading: 09:30-12:00
• Closing auction: 12:00-12:08 or 12:08-12:10 (random close)
• No afternoon trading on that day

Additional weekday arrangements: HKEX operates Monday to Friday. Investors should plan their funds and positions accordingly.

Practical Trading Tips for HK Stock Market

Choose suitable trading strategies

HKEX operates a T+0 trading system (buy and sell on the same day), but settlement is T+3. This means you can trade repeatedly within the day, but funds are only available after three working days.

During the morning and midday sessions, investors can use fundamental analysis to select blue-chip stocks for long-term holding or technical analysis for intraday trading. Additionally, HKEX allows short selling: if you are bearish on a stock, you can borrow shares from your broker and sell them on the secondary market. When the price drops, buy back to return the shares and profit from the difference.

Diversify trading methods

Besides direct stock trading, you can participate through:

Funds and ETFs: Track Hong Kong stock indices or specific sectors, suitable for passive investors.

Options trading: Offers call and put options with leverage, but with higher risk.

Futures contracts: Suitable for hedging and short-term speculation.

Contracts for Difference (CFD): Compared to direct trading, CFDs offer leverage of 1-200x, requiring only a margin deposit to control positions many times larger. CFDs support two-way trading, allowing short positions without borrowing shares, using margin directly. This amplifies both risk and reward; investors should carefully assess their risk tolerance.

Final Reminder Before Investing

Stock trading is not easy. Besides understanding the market hours and basic rules, successful investors need to establish a comprehensive risk management system.

• Follow economic calendars: Track key economic data releases to avoid volatility surprises
• Monitor real-time news: Capture market-moving news promptly
• Plan in advance: Design entry and exit strategies based on trading schedules

Getting started is simple: fill out your information and open an account → deposit funds through various channels → identify trading opportunities and place orders quickly. But success requires knowledge accumulation and disciplined execution.
