Have you noticed the slight upward trend?

١٧ سبتمبر ٢٠١٧

Seems it's not the $12 support line the stock bouncing on. There is another support line, pointing slightly upwards (~+0,5% / week). If you scroll back, you can see that it fits with the overall stock trend. In the past, it was a resistor multiple times, but it's mostly a support line since the Q4 of 2016.
