Trend Counter-Trend Lines
This analysis tool takes 4 local samples to product a trend line (green) and a counter-trend line (red). The concept of this is similar to finding wedges where 4 points (usually alternating highs and lows) are used to form the wedge. The purpose of this is to give a general long term direction and pattern.
