Evidence points to an ending diagonal followed by immediate weakness that took prices swiftly back beneath the starting point of the ending diagonal triangle.
The ED pattern comes complete with well-formed (a)-(b)-(c) internal wave counts. Remember, ED's are the result of a wave losing its impulsiveness (i.e.- losing the ability to create clear internal 5 wave count impulse moves for waves one two and three) and is a sign of weakness.
The general rule is a swift price decline back to where the ED started and often below. So buying bounces at this stage may be a bad bet.
