now ,three reasons for the target
1:if formed ,the reversal point will be at 0.786XC,that is "D"point
2:ab=cd pattern will be finished at "d"point
3:1.618ab extend is also at 54.8 aroud
4:descending triangle to break up the probability of large
from the chart ,we can find the above three points just in one position coincide,so I take 54.8 aroud as the target.
