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

I think the illustration in the picture is very detailed. The entire long-short Bollinger Bands system is actually composed of continuous openings and contractions. There will never be a trend of only opening but not contracting or only contracting but not opening. The trend of opening and closing is also caused by changes in the market. If it rises and falls sharply, the amplitude of the opening or closing will also become very sharp. As the market changes simultaneously, long and short Bollinger Bands are used in the operation. Indicators can completely avoid the disadvantages brought to us by other indicators with hysteresis or future functions.
