thanks for reply.
my understanding was quite at odds with this in some areas
to me, theab leg retrace of XA (which fib it goes to) begins the ident process for what shape it will be.
these shape show specific fib retracements that help with identification
for the bc leg retracing the ab leg, any of the shapes can have a ret of between .382 and .886 (specific fibs derived from .618, that is)
I understand a buttefly to not have an extension of more than 1.27. I got this idea from the following text
"In my experience, I believe an ideal Butterfly pattern requires a specific alignment of
Fibonacci measurements at each point within the structure. Most important, a mandatory 0.786
retracement of the XA leg as the B point is the defining element of an ideal Butterfly pattern,
and it acts as the primary measuring point to define a specific Potential Reversal Zone (PRZ).
In many ways, the ideal Butterfly pattern is like the Gartley pattern because it requires a specific
B point retracement and possesses a tighter array of Fibonacci ratios within the structure.
Specifically, the Butterfly incorporates a 1.27 XA projection with a “tame” BC projection, which is
usually only a 1.618. In addition, the Butterfly usually possesses an equivalent AB=CD pattern or
an Alternate 1.27 AB=CD pattern. Although the equivalent AB=CD is a minimum requirement, valid
Butterfly structures rarely exceed the Alternate 1.27 AB=CD completion point."

i will check the 1.2946 number, tho i think my posted chart in posts above show it
