1. Close the original master contract;

2. Establish a new position on the new master contract.

(2) The main reasons for the transfer of the main contract are:

1, because the futures contract has the last trading day, before the arrival of the last trading day, all the undelivered positions must be leveled gradually;

2. The margin of the exchange increases gradually with the approach of the last trading day. Considering the operating efficiency of funds, investors are more inclined to gradually adjust their funds to forward contracts with lower margin for trading;

3. The exchange not only began to adjust the margin 1 month before the delivery month, but also adjusted the required positions downwards, thus forcing investors to lighten their positions in the upcoming contracts. ?

(3) Matters needing attention:

1. The transfer shall keep the number of contracts unchanged and the buying and selling direction unchanged;

2. When transferring the main contract, you should act as soon as possible, and don't put it off until the end.

(4) Interpretation of the main contract:

The so-called main contract refers to the contract with the largest position. Under normal circumstances, the contract with the largest position has the largest turnover. Because it is the most active contract in the market and the easiest contract to clinch, speculators are basically participating in this contract.
