it has nothing to do with pretty formations
the dow sold off because Europe was diving at the same time.
it was mostly due to the commodity selloff in europe, combined with the dollar rumpusing on the Forex.
i bot at 11383 btw as mentioned in another thread.
among other things, big moves in indexes are often caused by margin calls and stops firing
many investors in european equities also invest in US equities e.g YM
basically, it is what we refer to as a sympathy selloff
there is no magical TA formation here. TA is merely a way to model trader actions
throw a DAX chart, a FTSE chart, and the same YM chart up that you just did
