Current-law scope and cautions
- CSRC's securities programmatic-trading rules took effect 8 October 2024 and require 'report first, trade later'.
- Exchange thresholds and differentiated HFT fees/monitoring can change. The current SSE/SZSE/BSE implementation rules identify high-frequency trading where a single account reaches at least 300 orders+cancellations per second or 20,000 orders+cancellations in a day; differentiated fees and other controls remain exchange-specific.
Use: This is a screening/estimation tool, not legal, tax, accounting or regulatory advice. Confirm the latest primary authority, regulator/exchange practice, local rules and transaction documents before acting.
