The contract price operates within a narrow range between the upper and lower Bollinger Bands. When the price crosses above the middle band (at the circled point) and the subsequent pullback does not break below the middle band, this can be used as a basis for entering a long position.

Since the Bollinger Bands are derived from the average of historical prices plus or minus the average volatility, if there is a significant price fluctuation on the day, the channel will deform accordingly. Therefore, Bollinger Bands have a lagging characteristic. Compared to other technical indicators, Bollinger Bands may be slightly inferior in determining trend reversals, but they are invaluable in identifying the end of a consolidation phase. Thus, the Bollinger Bands indicator can be used to analyze oscillating markets and determine the beginning of a market movement.
