Educational Fibo retracement

In this Example, GBOUSD had a swing from X to A

then retraced to point B 61.8 % of the previous swing.

THEN retraced to point C : did u pay attention to something ?

Point C : is the 38.2 % of XA, also it is 38.2 of AB which is amazing , as the first retracement was 61.8 , so the next numbers would be perfect, and that what makes Fibo amazing levels.

I tried to keep this as simple as possible.

thank you
