Mentioned it before, but worth repeating because it's such a great technique and it happened again today. At the places where reversals are expected on a set of stocks, you may find that multiple stocks will touch those levels at the same time. Stocks generally top/bottom at around the same time, even if by apparent co-incidence. This applies to smaller timeframes as well. Think about the logic. Stock X is expected to reverse at price Y, and Stock A at price B. However, they have disparate technical patterns. Yet, the general market correlation allows for the possibility of non-random, discernible movement when price approaches an area of interest. Multiple areas of interest generated simultaneously via different technical methods in correlated markets allow for more so-called coincidences.
