We have been following our economic analysis expecting bull markets in the commodity ETFs.  Here is DBA which could well be setting up a Kilroy (or inverse, reversed Srissasana upside down head and shoulders) bottom.  Today’s action could be a speculative (very) signal.  There is a possible signal when the downtrend line gets crossed (depending on the circumstances) and, of course the prudent trader’s signal is the penetration of the horizontal fence (neck) line.
