When the Graph Frequency/Time Span Selector is set to weekly, an uptrend change can be spotted when one bar is lower than the preceding bar (and vice versa). The problem is that when the Time Span Selector is set to weekly, the MACD-Histogram is only updated once a week rather than every day. Divergences happen daily -- not just once/week. If the weekly MACD-Histogram were updated daily along with the search capability suggested above (also using a weekly period), the result would be very powerful.
