Rectangles, and the cup and handle

Why doesn't ChartSchool accept a V-shaped bottom as a cup?

• Because V shapes are always bearish
• Because it calls a V too sharp a reversal; the cup should be a rounded U
• Because a V has no handle

What is the handle's retracement measured against?

• The whole prior advance
• The cup's advance: the recovery from the cup's bottom to its right peak
• The cup's depth below the left peak
