Andrews' pitchfork
Three parallel lines from three swing points: a median line that prices often return to, and two outer lines.
用通俗的话解释
Dr Alan Andrews observed that after three swing points, prices tend to come back to a line from the first point through the middle of the other two, about 80% of the time by his account. The outer prongs mark the edges of the likely path.
计算方法
Click the start of the move (handle), then the next high and the next low (or low and high). The median line runs from the handle through the midpoint of points 2 and 3; parallels pass through points 2 and 3.
Median line: from point 1 through the midpoint of points 2 and 3
Upper and lower prongs: parallel to the median through points 2 and 3如何使用
- Expect prices to gravitate to the median line.
- The outer prongs act as support and resistance.
- Failing to reach the median line hints at a reversal.
得出结论
- A break outside the pitchfork suggests the trend structure has changed.
示例
After a low, a high and a higher low on GBPUSD, the pitchfork's median rises; the price reaches it a week later and pauses.

注意事项
- Choosing the three points is a judgement call; different choices give different forks.
一点历史
Dr Alan Andrews taught the technique from the 1960s, building on ideas of Roger Babson.
