I use ONEQ as my NASDAQ index in investment overlays. Since 4/30/08 the overlay plot for ONEQ has 'flatlined.' If I try to plot several graphs using Graphs/Investment Overlay/Share Price/Options/list of plots, they all plot normally except that ONEQ goes to zero on 4/30 and stays that way for the rest of the plot.
What gives? Never had that problem before. When I look at the data, it is all there in the ONEQ.dat file.
