Double top and double bottom are simple, profitable and classic chart patterns. They are reversal patterns.
Double Top Chart Pattern :
In a double top pattern; the upper trend line consists two similar or nearly similar high points and the lower trend line consist a low point. This low point of lower trend line lies between two high points that joined to draw the upper trend line.
This pattern often called “M-pattern” as it looks like English letter “M”.
Trend line breakouts, uptrend line breakout and pullbacks of this pattern are very effective sell signal which is an entry signal to take a short position. Minimum possible price movement after breakout equals to the distance between two horizontal trend lines. Here is an example.

This high point of upper trend line lies between two low points. These two points joined together to draw a trend line. This pattern often called “W-pattern” as it looks like English letter “W”.
