I was hoping I could get some help writing a StockFinder custom index that would plot the number of stocks in a watchlist that have declined by more than a percent threshold each day. 

100 * ((price.Close - price.Close(1)) / price.Close(1))

I will want to play around with the threshold and direction but if this is written in either Blocks or RealCode I will be able to make the changes in the code myself.  Having the code for this custom indicator will help me toward developing more RealCode examples.

I know Blocks has been discontinued but is it possible to see the RealCode used to generate “RealCodeIndicator” blocks and other prebuilt blocks or to still generate new Blocks from RealCode?  Is there documentation for this?  Having this would help in using the Blocks for the existing Custom Indicator.  I've not found this is the RealCode documentation I have found.

Thanks.

I think I have figured out my questions but I might have more later.

No reply is necessary.

I am happy to read you were able to figure it out on your own. I would have used the Custom Market Indicator feature for this.
