.0021 is the next critical level for a number of reasons. It is strong resistance from several different views.  .0021 is the middle bollie, the 20 day MA, and support back from the Jan/Feb timeframe which now becomes resistance since we are trading below that line.

Yesterday's low of .0013 was a perfect bounce off the lower bollie. This stock has been trading between the lower and middle bollies for a long time now (with one brief dip below the lower bollie in early June).
