This needs to fall below 1830.00 for confirmation. As Harmonics are based on Waves, I envision the CD leg of the as a five wave down. Thus, the B point of the (yellow/orange) is likely the beginning of a two wave and the D point is likely the beginning of a fourth wave.
My preferred target for the D point of the is 1616.50.
Geopolitical note (08Apr2014): It is appearing increasingly likely that Russia will move into Eastern Ukraine in a manner somewhat similar to Crimea.
