We added the StockID in the Issues page. For example you can now quickly get SPY StockID (24262) right here.
The motivation for doing this is that you can use the StockID in any technical function that has a “series” parameter. For example this rule evaluates to TRUE when SPY is above the 50 bar average
It’s messy now. That’s what happens when you keep bolting on stuff. The $ was meant to represent data series we get from our vendor that are not stocks nor etfs, so mostly indices (which don’t include dividends). The ## was to clearly identify series from FRED. The single # overlaps with several things like Compustat macro data (which will be deprecated), parameter constants, and time series.
At some point we will brainstorm a cleanup and do a find/replace so your formulas are not affected.
Also, something new. you can now also type a StockId in the search box. That way you can quickly look up what an id corresponds to. Try typing 24262 or 4737 in the search box. I edited the original post in this thread with a screenshot.
