Masukura, in fact, is to see a futures product suddenly add positions in the session, and the range is relatively large, which can explain one thing, that is, there are forces attacking, and the two sides have a great dispute over the current price, and they are all investing in life and death preparations. If Masukura is accompanied by rising prices, it means that the bulls are trying to take the initiative to attack and are currently in an advantageous position. But whether it can continue to rise depends on the follow-up strength of the bulls and the follow-up reinforcements of the Air Force. Similarly, if the increase in positions is accompanied by the decline in prices, then the empty side is the strongest.
