程序化交易新规落地

Core Viewpoint - The implementation of regulatory guidelines for algorithmic trading by the three major Chinese stock exchanges aims to address the rapid growth and potential risks associated with high-frequency trading, ensuring a more equitable trading environment for all investors [1][2]. Group 1: Regulatory Framework - The new guidelines for algorithmic trading, effective from July 7, establish a three-tiered mechanism for account declaration, technical verification, and abnormal trading handling, marking the first comprehensive regulatory approach to algorithmic trading [1]. - The guidelines require high-frequency traders to pre-register and disclose their trading strategies, thereby reducing opaque trading practices and empowering retail investors [1][2]. Group 2: Trading Behavior and Standards - Algorithmic trading is defined as the automatic generation or submission of trading instructions via computer programs, with specific criteria set for high-frequency trading, including a maximum of 300 orders per second or 20,000 orders per day per account [2]. - The exchanges have identified various abnormal trading behaviors, such as excessive instant order submissions and frequent cancellations, which can disrupt normal market operations [2]. Group 3: Market Impact and Risk Management - The potential for algorithmic trading to create short-term liquidity issues and rapid price fluctuations necessitates the establishment of regulatory measures to mitigate these risks [3]. - The exchanges emphasize the need for consolidated oversight of trading activities across products managed by the same institution to prevent exacerbating market volatility during significant price movements [3]. Group 4: Additional Reporting and Fees - Investors engaged in high-frequency trading are required to fulfill additional reporting obligations, including details about their trading systems and emergency protocols, to ensure the security of the trading environment [3]. - The exchanges plan to implement higher fees for high-frequency trading activities as a market-driven approach to encourage a reduction in trading frequency and promote more responsible trading practices [4].
