The neckline of a double top is the:

Low between the peaks. The trough between the peaks.

The target is usually:

The pattern height projected from the break. Measure the height of the pattern.

Double Top and Double Bottom

Two failed attempts at a level, forming the M and W shapes.

A double top has two peaks at roughly the same level with a trough between them. It forms after an uptrend and suggests buyers failed twice. A double bottom is the W shape after a downtrend.

Confirmation is a close beyond the middle trough (the neckline). The measured target is the height of the pattern projected from the break.

Beware of patterns where the second peak is far above the first. That is a breakout attempt, not a double top.

Key takeaways

M and W shapes at similar levels
Confirm on a break of the middle trough
Target = pattern height
