In recent days, I studied event contracts. This mechanism actually has no trading signals to speak of. Even if the timeline is extended to 1 day, there is no 100% probability of ensuring that the index price at settlement is below/above the opening price, given the high likelihood of market pullbacks/rallies in the future. The extent of pullbacks/rallies is always limited; they may be completed in 12 hours or even less, followed by a market reversal. In short, the fault tolerance of event contracts is too low, making them less flexible than perpetual contracts. You might as well buy this as a lottery ticket; just make sure not to bet heavily. #事件合约
