Alcoa completed important pullback

This is a classic example of a horizontal resistance that becomes a support after a breakout. Alcoa successfully completed a pullback tot the former resistance which has become a significant support now.
In addition we can draw a upward trendline (support) under two bottoms. This upward trendline can act as support(stoploss) for the uptrend (long positions).
Current RSI level is historically high so we might see a cool-off period after which Alcoa will probably continue its uptrend.
