The contract price fell to a low of 1718 points, rebounding after breaking the middle band. During the upward movement, the price repeatedly broke through the upper band (at the circled points). When the price once again broke through the upper band of the Bollinger Bands (at the boxed point), the market fell and broke through the middle band of the Bollinger Bands, unable to return above the middle band. We used this as a basis to enter a short position. No technique is 100% successful; as long as an entry method has a success rate of over 60%, it is worth investors' persistence in using it. However, it is advisable not to rely solely on a single entry method to judge the market. For instance, using only the 'double top shorting method' may not guarantee a high success rate. It is essential to combine multiple techniques, ensuring that there are multiple entry conditions that 'resonate' each time we enter, as this can improve our success rate for each entry.
