Double tops and bottoms: how do you measure and trade them?

A double top is two failed attempts at the same high; the double bottom is the mirror. Both need a trigger between the two extremes, and both routinely morph into ranges or continuations.

What's your playbook?

• the tolerance between the two peaks or troughs
• the entry trigger and target projection
• the failure that taught you the most

The chart patterns guide covers structure, targets and failure rates.
