The king in the study of Bollinger bands found the soaring black horse before the common characteristics, summed up into a stock selection stunt, see the definition below.
(1) The Black Horse before the boom before the Bollinger bands first go flat for a period of time
(2) then the Bollinger bands gradually narrowed
(3) The end of the bollinger bands narrowing begins to shut
(4) When the Bollinger bands are closed and then the mouth is closed, the stock price moves along the bollinger bands
A selection stunt that meets the above conditions is called a horn blossom.
The longer the Bollinger bands take away, the larger the space that rises up after opening, and the day of the closing and opening is our best intervention point!
