improve stock chart coloring to reflect %
Add red and green saturation proportional to % change from start (1D open, start of 1st in 5D, 1M, YTD, etc.). If the change is barely positive, color should be just slightly to the green or red of gray. As the % change extends away from start, the color should become stronger green or red to give a truly dynamic sense of just what kind of gain we're looking at. It's kind of misleading to see a chart with a big trend up or down reflecting a 0.8% gain or loss, while a jump of 5% reflected in the same saturation of green or red just doesn't lend the emphasis merited by such a change.
