Andrews Pitchfork is an instrument consisting of three parallel trendlines. This instrument was developed by Dr. Alan Andrews. Interpretation of Andrews Pitchfork is based on standard rules of interpretation of support and resistance. 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 pitchfork «helve». Then, the second and the third trendlines outgoing from the above-mentioned rightmost points (significant peak and trough) are drawn in parallel to the first trendline. These lines are the pitchfork «teeth». Signal lines are drawn parallel to "tines" of the pitchfork. They are drawn at distances proportional to Fibonacci numbers. The distance between the median line (continuation of a "handle") and "teeth" of the pitchfork is considered 100%.
To draw Andrews' Pitchfork, one should select this object and then tap on the chart to add the first point (beginning of the "handle"). After that one should add the second point of the "handle" in a chart and drag the finger to add "teeth" of the pitchfork and signal lines at the necessary distance. Additional parameters will be shown at the top of the chart - three pairs of numbers. The first pair indicates the "handle" beginning, the first value is always equal to zero (because it is the initial point of the object); the second number indicates the distance between "teeth". The second and third pairs of numbers show distance along the time axis and price axis from the "teeth" to the "handle" beginning point.
Moving of the "handle" beginning point will change the direction of "teeth" only. The second point of the "handle" allows moving Andrews' Pitchfork in the chart without changing its dimensions. Points of "teeth" beginning allow changing the position of teeth separately; when one point is moved, the second stays in its place.
Pitchfork has the following parameters:
Common parameters of object are described in a separate section.
