Therefore, for the convenience of research, we take the form of "continuous" contract to observe. The "continuous month" here is not a fixed month, but always changes. For example, today is 12.22, so "continuous in the current month" is IF090 1, because IF08 12 has been delivered on 12+09 (the third Friday of each month). If 65438+20091October16 (the delivery date of if 0901), then "continuous in the current month" becomes IF0902 again.
IF is the code of Shanghai and Shenzhen 300 stock index futures, and the monthly continuity of IF is the monthly continuity of Shanghai and Shenzhen 300 stock index futures. ? Stock index futures will show the price for four months: the main contracts for the current month, the next month and the next two quarters.
At present, the corresponding prices are 1 108, 1 109, 1 12, 120 1: the main contract price in the same month;
Continuous next month: the price of one month after the main contract;
Continuity of the next quarter: the price of the next quarter after the main contract (referred to as the first quarter);
Quarterly continuity: the price in the second quarter after the main contract (3 months on the basis of the continuity in the next quarter).
The term of stock index futures, taking consecutive months as an example, refers to all consecutive contracts in the most recent month (not the current month, which is explained below), because the distance between contract months is different, and their price changes are also different. For example, the price in the delivery month is closest to the spot price, and the contract transactions after three or four months from the delivery month are the most. Therefore, for the convenience of research, we take the form of "continuous" contract to observe. The "continuous month" here is not a fixed month, but always changes. For example, today is 12.22, so "continuous in the current month" is IF090 1, because IF08 12 has been delivered on 12+09 (the third Friday of each month). If 65438+20091October16 (the delivery date of if 0901), then "continuous in the current month" becomes IF0902 again.
