The missing anchor.
Two analysts. The same price. One says 30.9%; the other says 61.8%. Give your study group the blank chart and let them find the missing detail.

The reveal
Both are right. They measured different moves.
For a linear upward swing, retracement fraction = (high − current) / (high − low). The high is 120 and the observation is 113.82, so the pullback is 6.18.
Anchor A: 100 → 120
6.18 ÷ 20 = 30.9%
38.2% level: 112.36
50% level: 110.00
61.8% level: 107.64
Anchor B: 110 → 120
6.18 ÷ 10 = 61.8%
38.2% level: 116.18
50% level: 115.00
61.8% level: 113.82
If you meant to study the larger swing's 38.2–61.8% zone, 113.82 has not reached it. Changing to the nested low after seeing a reaction changes the setup. A measured level is not an entry signal or a validated edge.
For a downward swing, a bounce level is low + fraction × (high − low). Check the drawing direction and price labels. The common 50% level is a midpoint convention, not a Fibonacci ratio.

A local maximum defined by two lower observations on each side is only confirmed once both later observations exist. On this hypothetical path, the peak at index 10 is confirmable at index 12. Placing its label at 10 does not make it knowable then.
This dataset has one value per observation, not full OHLC candles. For a real test, specify timeframe, high/low or close convention, pivot width and tie handling separately. A rule based on future bars must respect its confirmation delay.
Freeze the rule before you test it.
- Select: choose the timeframe, price convention and swing-selection rule.
- Separate: define location, confirmation trigger, expiry and failure conditions. A zone touch alone proves none of these.
- Record: keep failed and missed candidates. Do not redraw an anchor to rescue an example.
- Compare: test a similarly wide non-Fibonacci zone with other rules held constant on untouched data. Specify execution, exits and costs separately.
These are research-design prompts, not a tested trading strategy. No profitable continuation has been added to the chart.
Run it in ten minutes.
Two minutes to mark the swings, two to calculate, two to reveal the answer, two to discuss confirmation delay, and two to write a consistent rule and a failure case. The answer guide contains the complete exercise.
