There are two ways to measure how far above or below the price is from a moving average. First, as Greg Schnell has shown us several times, chartists can use the “percentage change tool” when annotating a SharpChart. This tool can be found just under the icon with the green-red line (support-resistance tool). Click to select, move to the moving average and click-drag from the moving average to the price. The example above shows a 3.3% difference between the 50-day EMA and the closing price.
