Wind and Cloud's Multi-Short Bollinger Strategy (Advanced Strategy)

1. The long and short Bollinger Bands system looks very simple, because it consists of three lines of different colors, but the meanings represented by these three lines are exactly what we need for operation:

To put it simply, the long-short Bollinger Bands system consists of the upper track, the middle track, and the lower track. The most important one is the middle rail, because it is the "middle rail line" in BOLL, which is the long and short line! The biggest role of the middle rail is to judge the strength of the long and short forces in the current trend, so that we can make a choice. judge:

​

When most of the K lines are concentrated above the middle rail, and the middle rail runs upward, it is judged that the current bull position is strong, and it should be held or bought on dips.

When most of the K lines are concentrated below the middle rail, and the middle rail runs downward, it is judged that the current short position is strong, and short selling should be made on rallies.
