I notice that the RUT-X has been the leading index (after the NDX-X) lately.  I ran an AD Line on its components and see this line greatly lags price on the daily chart.  To gain more perspective I changed the time frame to a weekly chart and was suprised to see on this scale the AD line greatly leads price.

I would not have assumed the disparity would have been so great between the daily and weekly AD line, with one showing a clear lagging condition and the other showing a clear leading condition. Based on this observation I must assume there is a "ideal" time frame from which to draw a correlation between the AD Line of components of an index and the price of the index, based on the underlying math used to create the AD line.  Any thoughts?
