The first is to adjust the intraday opening limit standard of stock index futures. CICC determined that since September 7, 20 15, the trading volume of a single product of Shanghai and Shenzhen 300, SSE 50 and CSI 500 stock index futures customers exceeded 10 lot, which constituted an abnormal trading behavior of "large trading volume in one day". Intra-day trading volume refers to the sum of the number of buying and selling positions of customers for all contracts of a single product in a single day. The number of open positions in hedging transactions is not subject to this restriction.
The second is to raise the margin standard of stock index futures contracts. In order to effectively guard against market risks and curb market speculation by reducing capital leverage, from September 7th, 20 15, the margin trading standard for non-hedging positions of Shanghai and Shenzhen 300, SSE 50 and CSI 500 stock index futures contracts was raised from the current 30% to 40%, and the margin trading standard for hedging positions of Shanghai and Shenzhen 300, SSE 50 and CSI 500 stock index futures contracts was raised from the current 65438+.
The third is to substantially increase the handling fee standard for stock index futures. In order to further curb excessive speculative trading in the day, combined with the current market situation, from 2065438+September 7, 2005, the handling fee standard for stock index futures closed on that day was raised from 1. 15% of the closed amount to 23% of the closed amount.
The fourth is to strengthen the management of long-term untrammelled accounts in the stock index futures market. In order to strictly implement the investor appropriateness system and strengthen the supervision of the actual control relationship account, CICC requires member units to further strengthen customer management. For financial futures customers who have not traded for a long time, member units should give risk warnings and strengthen the verification and verification of the true identity of customers. From September 7th, 20 15, before participating in financial futures trading, customers who have not traded for a long time should understand the current trading rules of the Exchange and its detailed rules for implementation, make a commitment to use the account for their own use, not to lend, transfer or entrust others to operate the account, and participate in the trading in compliance, and submit a letter of commitment to CICC through member units before participating in financial futures trading.
