Andrews' Pitchforks are FunHere's an example of a pitchfork drawn on the 2 weekly BNC:BLX chart, measured from the March 2020 low to the Nov 2021 high and completed at the Nov 2022 low, and then extended in direction and levels (up to 9 levels can be added).
The chart above makes for a solid example of how pitchforks can be used to derive a trend or channel and find solid support and resistance levels within it. They are also just fun to work with!
There are several types of pitchforks which can be tested until you've found one that works best for your chart. They are called Andrews' Pitchforks because they were originally developed by Alan Andrews, with several derivatives created by modifying calculation for the placement of the pitchfork's handle (the slope of its median line):
Normal Pitchfork - Andrews' original pitchfork tool.
Schiff Pitchfork - moves start of the handle line halfway to the base of the channel.
Modified Schiff Pitchfork - handle start is adjusted by a distance equal to half the difference between price values of its first two points (first low and high, or first high and low) of three.
Inside Pitchfork - handle adjusted to half of the vertical & half of the horizontal distance between the first two points of three.
In the example above, I chose a Modified Schiff Pitchfork , and then identified 3 points of consecutive highs and lows. In this case: low -> high -> low. You can choose to do the opposite of this and start from high -> low -> high, typically your first point should represent the beginning of a new trend.
Play around with trying this in different timeframes, and also try editing / adding / removing levels. You can try basic levels at increments of 25% or by utilizing classic Fibonacci levels (or both, as shown above).
Pitchforks are a type of Fibonacci tool, so I like using classic Fib levels. You could just use the Fibonacci Channel tool and get a similar result. But, the nice thing about utilizing a pitchfork is that it can help you identify a channel that may not be immediately obvious.
Here is another example of using a Modified Schiff Pitchfork to derive trends on a popular altcoin, BINANCE:HBARUSD :
Thanks for reading, I hope this was helpful to you. I learned more about pitchforks myself while working on this, and encourage others to do the same!
