Oops did not mean to step into the breech there, Graham's and my answer overlapped.

Thanks Graham.

The different starting dates of different symbols makes a difference to the values shown as it is a cumulative plot
The chart will always start at the first bar of the underlying symbol

Hi Everyone

This is driving me nuts. Why does the cumulative number change for AdvDecl after I've run the scan, plotted it and change tickers. For example, I've run this in AA, Scan( I believe I swiped it from TJ somewhere). Its then plotted. But the numbers for AddDecLine change depending on which ticker is shown on adjacent window. Why should AddDecl change with different tickers if I don't rerun AA scan?

I most be dense. This has gotta be simple!

Thanks

Dave
