If the opening is not much or only about one point, it means that the popularity is very calm, and both sides have no love for war for the time being. If it opens lower, it means that people who are eager to take profits or lose money can't wait, then the market is likely to turn bad. If it suddenly opens higher at the bottom and the amplitude is larger, it is often the time when the strength of both sides is fundamentally reversed. Therefore, when returning to the file, it constitutes a good opportunity to purchase goods and open positions. On the other hand, if there is a big gap when the general trend has risen a lot, it is often a symbol of the final outbreak of various forces, indicating that the bull market has ended, but it constitutes a shipping opportunity.
Similarly, the sharp opening at the bottom is often a blow to bear hysteria, but it constitutes a bottoming opportunity, while the opening at the top proves that people are distracted and want to escape first, which is also a sign of weak market. Although it rebounded later, it basically fell all the way. However, opening higher or lower in the middle of the market's rise or fall generally means continuing the original trend, that is, rising is optimistic and falling is bearish.
In order to eat goods smoothly, bulls often rush in after the opening, while bears will deliberately raise prices in order to complete the distribution, which will lead to rapid inflation after the opening, which is very common in strong markets. In a weak market, in order to bargain-hunting, bulls will plummet at the opening, while bears will be scared to sell desperately, leading to a sharp drop after the opening. Therefore, the market performance of 10 minutes before the opening is helpful to correctly judge the market nature.
