1. The balance of the settlement reserve in the investor's margin account is zero or negative, which cannot meet the requirements of additional margin within the specified time.

The above are the conditions for the outbreak of Shanghai and Shenzhen 300 stock index futures. Investment is risky, so I suggest you make a careful decision.
