Bitcoin has broken outside of its descending triangle, and has pulled back to a major resistance level. Personally, I'd look for candlesticks for insight into the next move, though a volatility play might be effective here as well, as the confluence of trendlines, horizontal support/resistance lines, and key moving averages trigger enough activity to move the market considerably. For the bulls, I'd want to see a close above resistance and these key moving averages before officially going long.
