一个回调使中枢B和A出现重叠部分,造成潜在的中枢扩展升级的机会 ==> spx morning dive to 1385 which hit the 中枢A, so the chance grow to 30F中枢 is secured. It does require spx swing around 1390--1410 area for another 2-3 days to successfully grow from 5F中枢 to 30F中枢.
You're right, Bear needs to be careful on 暴力拉升. That's the only hope for BULL, otherwise the 147x could be the end of super bull made by FED printing from 03/2009.
