This guide aims to provide a detailed overview of these rules, focusing on trading mechanisms, market participants, and compliance requirements.

1. Market Structure and Trading Hours

HKEX operates as a dual platform market, consisting of the Main Board and the GEM (Growth Enterprise Market). Each board has its own set of rules and regulations tailored to the types of companies listed and the nature of the investments.

• Main Board: This platform caters to larger, more established companies with a substantial trading volume and market capitalization.
• GEM: Focused on smaller, high-growth companies, GEM provides an avenue for emerging businesses to raise capital and grow.

Trading hours for HKEX are from 9:00 AM to 12:00 PM and 1:00 PM to 4:00 PM, with a lunch break from 12:00 PM to 1:00 PM. The pre-market session starts at 8:30 AM and ends at 9:00 AM, and the after-hours trading session is available for certain products.

2. Trading Mechanisms

HKEX employs various trading mechanisms to facilitate the buying and selling of securities. These include:

• Continuous Trading: The standard trading method where orders are matched continuously throughout the trading session.
• Auction Trading: Used primarily for the opening and closing sessions, auctions help determine the opening and closing prices of securities based on supply and demand.
• Automated Trading: HKEX's trading system, known as the HKATS (Hong Kong Automated Trading System), supports high-speed electronic trading, providing a platform for efficient order execution.

3. Order Types and Execution

Traders can place various types of orders, including:

• Limit Orders: Orders to buy or sell a security at a specific price or better. These orders remain in the market until filled or canceled.
• Market Orders: Orders to buy or sell a security at the best available price. These are executed immediately and are used when speed is essential.
• Stop Orders: Orders that become market orders once a specified price level is reached. These are used to limit losses or protect gains.

4. Margin Requirements and Leverage

HKEX allows trading on margin, which means traders can borrow funds to increase their buying power. However, margin trading involves significant risk, and traders must adhere to margin requirements set by the exchange:

• Initial Margin: The minimum amount that must be deposited to open a margin position.
• Maintenance Margin: The minimum amount that must be maintained in the margin account to keep the position open. If the account balance falls below this level, a margin call is triggered.

• Trading Halts and Suspensions: HKEX may impose trading halts or suspensions on securities to address unusual market conditions or significant news events. These measures help maintain fair trading conditions and protect investors.

6. Penalties and Enforcement

HKEX enforces its rules through a range of penalties and disciplinary actions for non-compliance. These may include:
