1. Spot position is an indicator in market reality. Futures index is an index traded in the futures market. The two are equal in theory, but in fact, under the influence of news expectation, futures tend to lead the spot index. . . . .

I can't explain this. He is the algorithm. . . Just remember. . .

There is no topic about the futures settlement price on September 17, and the profit and loss results calculated according to different settlement prices are 3000-3700 respectively. "March 1 spot quotation" is 3324 "March 1 futures quotation" 3400.

Profit and loss of futures positions =300 yuan × (September 17 futures settlement price-March 1 daily futures quotation )× The algorithm in short contracts is wrong. He used September futures settlement price 1 July-March spot quotation1.
