Double top and double bottom

The supply-demand balance then reverses; supply outpaces demand (sellers predominate), causing prices to fall.

The time between the two peaks is also a determining factor for the existence of a double top pattern.

If the tops appear at the same level but are very close in time, then the probability is high that they are part of the consolidation and the trend will resume.

The pattern is formed by two price minima separated by local peak defining the neck line.

Volume should show a marked increase on the rally up while prices are flat at the second bottom.
