The week's question
In March 2025, in the thread "Re: OT, out", Umm asked the members: "Do you think it is because America is made up of magical soil that makes businesses based in America magically profitable?" This week it is put to everyone again. The button below opens the small thread re-asking it - read what others have said so far, then give your own answer as an ordinary reply.

"Here is the formula: =if(C6>0%,"BUY",if(C6<-4%,"SELL","No action"))"

Thank you Ray - that formula was very helpful in groking the nested IFs!

I see the utility of using weeks rather than days to avoid confusion - but that raises a related question - for use in Google Sheets, should the formula indeed specify 365 days or something like 252 which is what I thought was the equivalent of 52 weeks in Google Sheet-speak?

"B6 is the average of =GOOGLEFINANCE(".ixic", "price", today()-365, today(), "WEEKLY")
That is, the average of the last 52 weeks of IXIC,"


Sorry if this is a dumb question.
