The fifteen-minute vibration frequency of futures refers to the number of fluctuations in the price of a certain variety in the futures market within 15 minutes. This indicator can be used to reflect market fluctuations and trading activities. Specifically, if the price of a certain variety fluctuates for many times within 15 minutes, its vibration frequency will be higher; Conversely, the smaller the price fluctuation, the lower the vibration frequency. In actual trading, analyzing the vibration frequency can help investors better grasp the market trends and changes and formulate more appropriate trading strategies. For example, high vibration frequency may mean high market risk, and trading needs to be more cautious; If the vibration frequency is low, it may mean that the market is relatively stable and corresponding trading strategies can be adopted.
