The general understanding is this, but there are some exceptions. The so-called futures is the expectation of future spot prices, so in most cases, the trend of spot and futures prices is the same. No one needs to stipulate, this is stipulated by the market. However, under some artificial specific circumstances, the two may also have opposite trends. For example, futures have staged short selling in recent months, causing spot prices to rise, while distant months may dive because of lack of support. But this kind of situation is rare after all. Therefore, in most cases, the trend of spot and futures is the same, rising and falling together, and the general futures price is more sensitive and flexible than the spot price.
