Call/Put ( C/P ) ration. I attached 2 pictures from the datasheet of my broker and calculated C/P ratio for 20/11/2015 and 18/12/2015 ( options expire day ). My calculation for November and December C/P Ratio of 2.5 & 6.7 respectively. IMO: Strong upside will go through December and probably we will see levels in range between $6 and $8 dollars very soon.
