Following up with my HAL daily chart from 21 days ago, my short was triggered at 56.90 solely based on anticipation that a challenge to underside of uptrend channel bottom would fail. When OPEC decided not to cut production, (i suspect they at looking at technical chart), price of HAL plunge straight down. I took 90% of my profit at 41.99 leaving just 10% to see if i can get any lower.
