Head and shoulders

用通俗的话解释

The left shoulder and head are made in an uptrend. The right shoulder fails to reach the head's high: buyers are weaker. When the price breaks the neckline, the uptrend has turned. Upside down, it is a bottom pattern.

计算方法

Click the start, left shoulder, first low, head, second low, right shoulder and the end. The tool draws the neckline through the two lows, then the targets (61.8% and 100% of the head's height measured from the neckline) and a stop beyond the right shoulder.

Target after the break ≈ neckline − (head − neckline)

如何使用

• Sell (or exit longs) on a close below the neckline; place a stop above the right shoulder.
• Measure the target as the head's height projected from the neckline.

得出结论

• Volume often falls on the right shoulder and rises on the break.

注意事项

• Many patterns never break the neckline; wait for the break.
