There appears to be a reoccurring pattern between here and the last bull run where the price bottomed out 3 times only to fake out and plunge again. I know it's not technically a triple bottom, but the two highlighted areas do appear to be similar with candle wicks from the first bottom reaching past the other two later bottoms. I suspect it will be a similar pattern here. Support at $315 is strong, but it probably won't last, especially with the lack of demand shown by the low here.
