Rates on the Ten-Year Note climbed to within inches of the 4.48% high recorded on March 27, but there is reason to doubt they are about to break out.  Specifically, the pullback from the high breached a Hidden Pivot midpoint support at 4.35%, implying more slippage to at least 4.28% is no worse than an even bet.  Using the futures contract, traders can get short at 4.39% (interpolated) with a stop-loss at 4.44%.
