The reverse pattern generally refers to the K-line pattern at the end of the upward trend and the end of the downward trend.

There are many K-lines for judging inversion in technical analysis, such as double bottom (top), head and shoulder bottom (top), island inversion, multiple top (bottom), arc bottom (top) and so on.

The specific reversal forms of K-line combination generally include: pagoda turning black, pagoda turning white, evening star, morning star, three crows, three red soldiers, long cross star above, cross star below, etc. The probability of these reversed forms is relatively high.
