Arcellormittal formed an inverted H&S on the Weekly timeframe. Neckline has been broken and retested, and is currently rising on a nicely defined wedge.
Leg D-E is underway, and should take us at least to the 35-40 range in the following weeks, which represents a 30-40% gain.
Most probably entry point is @ 27.550, which would be leg 2 of D-E. In the H1 timeframe, this is the confluence of recent support, 50% FIB from Leg 1 and 161.8% extension from (a-b) in Leg 2. (yes, the yellow shaded area)
The chart is not that clean, but you get the point :)
