A Flat is a three-wave pattern labeled A-B-C that generally moves sideways. It is corrective, counter-trend and is a very common pattern.
• structure is 3-3-5
• wave B moves beyond the start of wave A
• wave C ends more substantially beyond the ending level of wave A
• appears in wave two or four in an impulse, wave B in an A-B-C, wave X in a double or triple , or wave Y in a triple threes
An is a special type of pattern that occurs at times when the preceding move has gone too far too fast, as put it. A very small percentage of ending diagonals appear in the C wave position of A-B- C formations. In double or triple threes, they appear only as the final "C" wave. In all cases, they are found at the termination points of larger patterns, indicating exhaustion of the larger movement.
• structure is 3-3-3-3-3
• a shape within two converging lines
• wave 4 must trade into a territory of a wave 1
• appears primarily in the fifth wave position, in the C wave position of A-B- C and in double or triple threes as the final "C" wave
