A Dollar Index bounce as a failed-support, Fibonacci and volume test

The bounce and the open question

After a June 2010 swing high, the US Dollar Index declined until support near 80, formed in a February-March 2010 consolidation, and then reversed higher over six sessions. The daily bounce was located at 80.17.

The daily-chart question posed in the archive was whether the rebound was only a retracement inside a new downtrend or a reassertion of a bull phase that began in December 2009.

Failed pullback support as information

A labeled pullback support failed as the decline accelerated. That failure was treated as a cue that price could continue toward the next significant support. The index then reached support near 80, formed in the February-March 2010 consolidation.

Support and resistance, in this workflow, means prior swing and consolidation zones that attract reactions. A break or failure of a zone is read as information about the next likely test.

In May 2010 the index moved through resistance near 83.25 and continued higher. The archive presented that move as the inverse case of a support failure: a break of resistance using the same logic in the opposite direction.

Overhead resistance as a cluster

After the bounce, overhead resistance was mapped as a band from 84.69 to 85.76, matching the 50 percent and 62 percent Fibonacci retracements, with a former pullback support at 85.35 also overhead.

Fibonacci retracement here means percentage pullbacks of a prior swing, used to locate overhead resistance after a bounce from support. Pullback support is a support shelf formed on a pullback that, once violated, is re-read as potential resistance on a later rally.

Those nearby levels form a resistance cluster: a band of Fibonacci retracements plus a former pullback shelf, treated as one decision zone rather than a single line.

Volume and bar character at the reversal

Volume-price analysis checks whether participation expands on a reversal off a named level before treating the bounce as meaningful. At 80.17, volume on the reversal was described as exceptionally strong.

Wide-range bars classified as professional activity at major support were used as a reversal cue, while amateur bars were tied to failed breakouts at key support or resistance. That split is the professional-amateur-bars reading: wide-range activity near major support or resistance versus bars clustered around failed breakouts at those same zones.

How the stacked test is graded

Editorial reading: TradersWeek does not treat the six-session rebound as a new trend on its own. The failed pullback support, the exceptionally strong volume at 80.17, and the 84.69 to 85.76 resistance cluster are stacked so the bounce can be graded as a hypothesis.

The archive question, retracement inside a new downtrend versus reassertion of the bull phase that began in December 2009, remains the question the stack is meant to test. This article does not score either side.
