Could you please explain how 48c is a resistance level?? I'm trying to calculate retracement levels using fib channels and my chart tells me that the next key resistance levels are 42c, 45c, 49c, 54c and 60c. In terms of most volume churned by price levels for the past 2 months it shows that most of the churns went through at 44c, 46c, 47c, 51c and mostly at 52c (<- which I assume will be the key point to confirm a full breakout instead of just a temporary uptrend). Now, I don't claim to be an expert chartist - far from it really, but any insight you might have to correct my interpretation would be appreciated :)
