actually i have another question

this doesnt seem to work out mathematically for me

in my drawing below, the #s represent the height or distance on the Y axis of the line segments
and not the retracement level. Imagine it is a coordinate axis with X at (0,0)

lets say line segment XA has length of 1.

AB is a .618 retracement of XA, therefore length AB = .618

lets choose .382 as the retracement of AB for BC.
therefore length BC = AB * .382 which is BC = .618 * .382 = .236
BC = .236

Now to calculate CD we have to do something else first.
We know D is a .786 retracement of XA, therefore D has a Y value
on our coordinate plane of 1 - .786 = .214


If we add the line segments up we should get XA - AB + BC - CD = .214

Lets do that

1 - .618 + .236 - CD = .214
CD = .404

However CD is neither 1.27 or 1.618 of BC..huh!?

1.618 * .236 = .381
1.27 * .236 = .299
