Andrews' Pitchfork is a channel-based analysis technique developed by Dr. Alan Andrews. The channel drawing technique uses three parallel trend lines to show areas of support and resistance. The three parallel lines are created from three consecutive major peaks or troughs. The trend lines automatically generated by plotting three points on a chart, each marking an important pivot point.The use of Andrews' Pitchfork can help traders identify potential support and resistance levels, as well as entry and exit points for trades. In addition, the tool can be used to measure price volatility and momentum changes over time periods ranging from minutes to years.
