The specific rules are as follows:

2. Since February 3, 20 18, the regulatory standard for intraday over-trading of stock index futures has been adjusted to 50 lots of single contracts (20 lots of original single varieties), and the number of positions opened in hedging transactions is not subject to this restriction;

After the 20 15 bull market crash, stock index futures became unpopular, so it has been restricted, resulting in the inactive stock index futures market. Now, the relevant departments have liberalized some restrictions on stock index futures, which is not only something that all parties are eagerly looking forward to, but also dialectically, the liberalization of stock index futures at this time represents the concern of policy makers on the stock index futures market. After all, liquidity is everything in financial markets.
