BP: in week 6 of a sell signal, an unconvincing bounce

BP is in week 6 of a sell signal, and the week just closed up 0.7% with buying volume back at 81%. The bounce doesn't fully convince, though: the MACD histogram fell to -1.18 and CMF worsened to -0.315, the most negative reading of the past 4 weeks. Price sits between the first resistance, in the 38.4 area, and the first support, in the 37.3 area.
