Published structure and the limits of its projection
Bill and Brian Wolfe describe the bullish sequence as a low at 1, a high at 2, a lower low at 3, a rebound high at 4 and a low at 5 that can exceed the 1-3 line. The bearish sequence reverses the highs and lows. Their rules require 1-3 and 2-4 to converge.
- In their terminology, the boundary intersection gives Estimated Time of Arrival (ETA). The 1-4 line evaluated at that time gives Estimated Price at Arrival (EPA). Their practical discussion says they do not count on ETA.
- The W-1 example below adds numerical filters, pivot confirmation and expiry for reproducible review. These are teaching choices, not a claim to reproduce every part of the discretionary method in the source.
- An ordinary wedge breakout can be described with two boundaries. W-1 also requires a particular five-point order and a separate 1-4 projection; a wedge label alone does not satisfy these tests.
