"Just tried adding a moving average to the following chart, using the "charting" option: "London Spot Gold, chart: x $ Index 10 yrs (one of the drop-down options) Nothing happened. The same in both Firefox and IE, so can't be the browser. Any suggestions on how to solve this?"

Eoin Treacy's view Thank you for this email, which others may also be interested in. Unfortunately, the Chart Library is not yet capable of applying moving averages to ratio charts which means that it is not possible to apply an MA to the chart of Gold shown in terms of the Dollar Index.
