Andrews Pitchfork

Andrews Pitchfork, also known as Median Line Studies, is a line study that uses three parallel trend lines to identify possible levels of support and resistance.  This tool was developed by Dr. Alan Andrews.

Andrews Pitchfork, also known as Median Line Studies, is a line study that uses three parallel trend lines to identify possible levels of support and resistance.  This tool was developed by Dr. Alan Andrews.

Andrews Pitchfork Calculation

Three points on the price graph are identified.  The first point is either a major peak or trough.  The second and third points are to the right of the first and consist of one major peak and one trough.

The first trend line of the Andrews Pitchfork begins at the left-most point selected and is drawn so it passes directly between the two right-most points. This line is the "handle" of the pitchfork.

The second and third trend lines are then drawn beginning at the two right-most points (a major peak and a major trough) and are drawn parallel to the first line.

These lines are the "tines" of the Andrews Pitchfork.

Andrews Pitchfork Interpretation

Trend line support and resistance are determined from the trend lines drawn.  Note that it is nearly impossible to verify the validity of the Andrews Pitchfork chart study as it cannot be back-tested using computer algorithms.
