Is there something equivalent to the global variables that existed in WLD4? I could not find anything in the Help files or on the Forum.

I would like to count all of the days that all of the stocks in a watchlist meet a certain set of requirements over the past 60 days, and without a global variable capability I do not see a way to address it.

Any Ideas?

Fortunately, your task may not require the added complexity of global variables at all. The key is looping by DataSetSymbols:

Number of stocks up a certain percentage over a period
Number of stocks above their moving average for N periods

If it's a simple price/indicator/fundamental-based condition to be run before the main loop, you're lucky. If it's some Position-based criteria, the technique won't apply.

Sure they exist if you look up in the QuickRef:

Global data?

More examples:

Passing indicator/bar data between Streaming Strategies via files
WealthScript Techniques | Access Data from the Internet on-the-fly
SetGlobal, GetGlobal from DLL

Thanks Eugene!

BTW, I did a search in the User Guide and The Programming Guide. I mistakenly thought that all of the items in QuickRef would be in those two help files. Obviously not!
