Chart tells the story, regarding volume. Major volume on first week of accumulation (.0001-.0003), then major drop off in volume while accum. continued. Friday's volume cleared out 80% of early profit-takers, showing massive amount of 'buy and hold' left.
People don't hold unless they see much bigger gains. I wouldn't be surprised one bit if Monday turns out to show another disproportionate amount of buying vs selling. As long as profit-takers sell at ask, the ratios can remain high, which continues to build an impressive chart.
