If I have a series of dates and want to see how items in a watchlist perform visually by having vertical line at specified dates  is that possible to save the layout to see scanned results on the layout against the days and be able to call the layout with particular vertical lines placement in the future?

I want to look at particular days of a week or month and see if there is a change of trend for the stocks in a particular watchlist to scroll through.  Would like to have various colors for particular dates also.

You can click on the date scale along the bottom of the chart and select Add Date Pointer to add a horizontal line to the chart at a specific date / time.

You can then right-click on that date pointer and select Properties to adjust things like the color of that particular data pointer and if it is draggable or not.

You can reference these date pointers (and thus the dates of the data pointers) in Block Diagrams.

There isn't any syntax for referencing the dates in RealCode, but Block Diagram based indicators on the chart can be referenced in the RealCode. Unfortunately the links to the Date Pointers do not survive reloading the chart if you save the chart or shut down and restart StockFinder.
