In my humble opinion...You can look at CNQ & MEG to see what's coming down the pipe for ATH.
Happy to have sold this time at 3.45 after so many times of watching my profits evaporate.
In the same period I also sold out of all my ENB, MEG, CPG, WCP, BNS, CM,
Been nibling at BTE, GXE, CJ, and I even bought some Credit Suisse ticker CS at .85 for long hold.
I could see ATH revisiting 2.00 range as the sector remains under pressure for longer.
