The core content of the quantitative trading rectification plan is as follows:

1. Trading speed limit: The entire market will increase the optical fiber delay by approximately 200km, compressing the speed advantage of institutions and reducing unfair competition caused by differences in technical speed.

2. Exchange port sharing: The brokerage service ports hosted by the exchange will no longer allow a single client to monopolize; multiple clients must share, limiting quantitative institutions from using ultra-fast trading cabinets, which may require a shift to external third-party custody.

3. High-frequency trading regulation:

Each account can report/cancel a maximum of 300 orders per second, with a daily maximum of 20,000 orders.

Research on charging higher traffic fees and cancellation fees for high-frequency trading, increasing trading costs.

4. Penetrating regulation: Requires quantitative trading accounts to be filed and disclose strategies, strengthening monitoring of abnormal trading behaviors.

5. Risk prevention and control:

The contract position of a single account must not exceed 5% of the total market position.

The margin requirement for perpetual contracts is 150%, to prevent excessive leverage risks.

6. Acceleration of regulation: The fair trading regulatory plan originally scheduled to be implemented in May 2026 will be brought forward to within one month, demonstrating regulatory determination.

These measures aim to maintain market fairness, reduce abnormal fluctuations, and guide the standardized development of quantitative trading.
