Last post on the HSI suggested that an impulsive decline was likely complete, & a Corrective Rebound towards 23600 was due. We did get a whimper of a rebound up to 23275 but failed to close the gap. At the close HSI breached the previous low of 22800, suggesting more downside.
However, there could be support here just under 22700 based on the parallel channel, as suggested on the chart. Also note the very short-term oversold condition. An overlapping & messy rebound towards 23600 is likely to set up the right shoulder of a Head & Shoulders pattern. Look for a break out of the downtrendline in blue, and a break above 22800 as clues.
