DIA (Dow Industrials ETF) fell strongly over the last two days. My chart shows a Resistance Line and Support Zone based on performance for one year. The price fell only to the top of the Resistance Zone today. If this is just a downswing and not the commencement of the expected Big Dip, then the graph will bounce back from either the top or the bottom of the Support Zone. We watch to see what will happen next.
