The dollar went from +0.1% to -0.2% in the past 2 hours, and the market went from -0.4% to +0.5%.

Don't over think it; if you are bringing anything above and beyond first grade logic to this market, it is too much.  It just amazes me that literally armies of PhDs can't come up with an algorithm a bit more sophisticated than IF dollar zig THEN market zag.
