Thanks for being a customer.
The data I am able to gather in my tracking spreadsheets has been very insightful. Marketdata has made it so simple to collect market price action on options spreads that is not available anywhere.

Good product. I do have occasions when formula is correct and I get an error message ... only to see, a short time later, that data has populated. All in all, though, I'm very satisfied to have the capacity to do market analysis more efficiently than having to download from an outside source.

Why not show on the menu when the last update occurred. Thad would help manage the refreshments of my data more easily.

Unfortunately this is not possible because each formula refreshes at a different time depending on when the parameters change, when you add/remove columns or rows before it, etc. You can add the "date" attribute to each formula's output to see the date/time the data was last updated.
