Here's a channel that has been telling the technical story of T-Mobile. At the tops it has been consistently selling-off and at the bottoms, it gets bought up. Personally, I look to sell the pink zone or slight above and buy the green zone. If it breaks out of green however, I would liquidate all longs and go short.
Currently, it is pulling back from channel highs and looks to at least fill the gap.
Please check my channel tutorials for more info on how to use them/draw them.
Cheers.
