Generally speaking, futures prices will run in the channel formed by pressure line and support line. When the bollinger band moves horizontally, it can be regarded as the current trend market running sideways, which belongs to the normal range.
3. When the futures price crosses the upper rail, it will form a short-term retracement, which can be regarded as a short-term selling signal. When the price crosses the lower rail, it will form a short-term rebound, which is a short-term buying opportunity.
4. After the futures price moves sideways for a period of time, the fluctuation range of the Bollinger Band shows signs of narrowing. When the upper rail and the lower rail are close to each other, it means that there will be changes. At this time, if the price continuously crosses the upper rail, it means that the price will run upward, while when the price continuously crosses the lower rail, it means that the price will run downward.
5. The futures price is on the upper rail and runs closely on it. Needless to say, it is in a strong state and obviously rises unilaterally. When the futures price goes down or runs close to the lower rail, the unilateral market drops significantly. The unilateral type is not easy to encounter, and generally fluctuates downward or upward. Therefore, futures should be patient and can hold back.
6. When the price crosses the middle rail and runs in the middle rail and the lower rail channel, it obviously oscillates downward. When the futures price goes above the middle rail and runs in the middle rail and the upper rail channel, it oscillates upward. Of course, the bollinger band index is also more practical. It depends on whether investors can hold back. Holding back is to make money, but you have to lose money or lose money.
