$1.90 is the previous low from back in June, and $2.11 is the most recent closing high, for it to be a long upward trend it needs to get above that recent high before going back down.
I expect we will get through $1.90 pretty quickly, then work harder to get to $2.11, but charts are less useful in situations like this, low volume traded, and a seller sitting on the sidelines taking any significant buy orders that pop up. What that seller does has more influence on the SP than anything else.
