CD leg usually slopes at an angle that is wider than the AB leg.CD can be an extension of AB anywhere from 1.272% up to 2.00% and even greater.CD must be 127.2% or 161.8% of AB or of CD.Point D must be a new low below point B.In strong markets, C can trace only up to 38.2% or up to 50% of AB.C usually retraces to 61.8% or 78.6% of AB.C must be lower than A and must be the intermediate high after the low point at B.When AB is identified, the next step is to plot BC.Swing points A and B form the highest high and the lowest low of the swing leg.The chart below shows the three different ABCD bullish patterns. ABCD extension: CD leg is an extension of AB between 127.2% – 161.8%.Classic ABCD: In this pattern, the BC is a retracement of 61.8% – 78.6% of AB, with CD being the extension leg of 127.2% to 161.8% (equal in price distance).Price and Time: Under this type of ABCD pattern the amount of distance and the time it takes for price to travel from A to B is equal to the time and distance from C to D.Within the ABCD patterns, there are 3 types as mentioned below. It was developed by Scott Carney and Larry Pesavento after being originally discovered by H.M Gartley.

The ABCD pattern shows perfect harmony between price and time and is also referred to as ‘measured moves’. The ABCD pattern ( AB=CD) is one of the classic chart patterns which is repeated over and over again.
