One point, 300 points,
The contract value is 2800 * 300 = 840,000;
The minimum margin for 5 lots of stock index futures is:
840,000 * 5 *12% = 504,000 RMB.
Theoretically, 504,000 yuan is used to do 4.2 million transactions (= 840,000 *5), that is, the rise and fall of investors' rights and interests is based on 4.2 million yuan, so the high risk and high income of "leverage" comes from this.
Therefore, if the account is only 504,000, it is not suitable to be a 5-hand stock index, because a slight reverse fluctuation margin is not enough.
If you want to be a 5-hand stock index, it is recommended to be at least 1 10,000-10.5 million.
