Wow, another intraday reversal, but this one is to the downside (for a change)!
Call this Somersault Tuesday!
Let's notice that the index reversed and has declined sharply, violating intraday support at 1871.50.
That leaves the near-term price structure vulnerable to a test and break of 1865, and possibly 1857.50, which will inflict some damage to the Feb-Mar uptrend.
At this juncture, only another sharp upside reversal and climb above 1882.25 will send the shorts for cover, and the e-SPH to new all-time highs.
