Andrews’ Pitchfork is an instrument consisting of three parallel Trend Lines. This instrument was developed by Dr. Alan Andrews. Interpretation of Andrews’ Pitchfork is based on standard rules of interpretation of support and resistance lines..
The first trend line starts in a selected extreme left point (it is an important peak or trough) and is drawn exactly between two extreme right points. This line is the "handle" of pitchfork. Then, the second and the third trend line issuing from two above-mentioned extreme right points (important peak and trough) is drawn parallel to the first one. These lines are "tines" of the pitchfork.
