BTC ETH Next, let me share with you the idea of conducting a survey: 1： At present, the negative premium of Big B Network has just disappeared and is becoming a positive premium. It is best to wait for the positive premium to become even higher and continue for a period of time; The use of this indicator requires understanding that it takes time for the main force to sell or attract funds, which means that the main force on the Big B website needs to buy or sell for a period of time, and then follow in and become the wave of people who enter later; 2： The significant decline in the position of the pancake contract is also a signal of reaching the top, which represents that retail investors who are chasing after long positions at high levels have been cut off or liquidated; 3： If the funding rate of Da Bing starts to decline and approaches negative levels again, it seems a bit difficult at present because FOMO's sentiment has risen and the contract has started to have a premium; Summary: The idea of efficient bottom line and top line is similar, and the data used here is also basically the same. The bottom line has added the position data to determine whether the bulls have surrendered on a large scale;
