Not only is the shorter-term oscillator overbought but the intermediate-term 30-day moving average of the advance/decline line will get overbought next week.
More than that, while the cumulative advance/decline line has made higher highs throughout this rally, cumulative volume (up minus down volume) stalled out a month ago.
Typically, important turning points are accompanied by negative divergences in market breadth indicators, such as the advance/decline line or the number of stocks making 52-week highs.
