It’s time for another rework. I’ve hit the thing fairly hard this time — for a relatively small improvement in absolute performance but I think a substantial gain in structure and understanding.

You may know that Yahoo Finance has for a long time provided near real-time global stock quotes via its website and via a web API service, which many have used as a convenient source for Excel data. There have been lots of VBA implementations and even a direct spreadsheet formula implementation (no VBA). Unfortunately the API service was abused to the extent that some even purported to sell trading applications based around it (go . . . → Read More: Near real-time Yahoo stock quotes in Excel ![]() The fuss recently about a fairly minor fix to the fairly ordinary estimate of global temperature change provided by satellite remote sensing has prompted some long-overdue action from me.
