Looking back to october 1990 CL1! hurt a resistance at 41.15$ We had a support on march 18, 2015 at 42.03$ We had a new low on aug 14, 2015 at 41.35$ These 3 values are close enough to make a support I think More than that we are having a bullish divergence on RSI on monthly and weekly basis. RSI is also making a (bullish) wedge on daily basis.
Could be a good entry point, please trade carefully
