AB-CD Pattern

This tool allows you to plot the AB-CD pattern manually onto a chart.

The AB-CD pattern is made up of of 2 price legs which are similar. Specific Fibonacci values are used for each point in the pattern, (with some tolerance). For a valid pattern the C point will need to retrace to one of two values (0.618 or 0.786), with the BC projection being either 1.27 or 1.618.
