Apple has been bouncing around $90 since October.  Is that support going to hold?  One way to gauge the strength of a support level is to use the "Vol by Price" overlay - the horizontal histogram on the left side of this chart.  It adds up all the volume for any days on the chart that close within the bars price range.  The bars in two colors - one for volume when the stock closed up and the other for when the stock closed down.  In the case of AAPL, the long horizontal bar shows that lots of volume has occurred in the $90 - $100 range and that is the most important support level on the chart right now.  It also shows that the volume on "up" days (gray) is almost equal to the volume on "down" days (light blue).  The Vol by Price overlay clearly shows that 90 is the battleground for AAPL right now.  With AAPL oscillating around $90 (possibly in a triangle pattern), the battle is getting very heated and is worth watching closely in the coming days.
