The test lower after the opening swing high was met with responsive buying yesterday. Once back inside the prior day's range the  market one time framed higher on the 30 min until the last hour of the day, after tagging the prior day high. Volume was fairly low at 1.3m contracts.

Failure to hold below initial support yesterday keeps the short term bullish bias intact, and only once there is acceptance below there and rejection on a test from underneath does the case for a corrective move increase.
