I would love to be able to extract the y values from line indicators in the TradingChart. For example, the following code creates acceleration bands for the data. I would love to return each successive y value in the list of the indicator lines that are produced.

TradingChart[{"MSFT", {{2009, 1, 1}, {2009, 3, 31}}}, {"AccelerationBands"}]
