As in the chart, the point D is a PRZ (potential reversal zone) where FIBO 1.272Xa, 1.272AB=CD, and FIBO 1.618Bc converge at there. However, we should wait the price breaks support Y and Z, only we can expect a bullish trend begins at point D. Additionally, it also means that price now may have a bearish trend until point D.
