No Data again today at UTC 14:57:47, USD/CAD. I paid closer attention this time. I saw it ~15:10. diag.txt was 1k, timestamp 15:08. Started Shadow Copy and looked again - still 1k, but timestamp 15:10. Shadow Copied diag.txt contains only messages from after 15:10 - the only timestamp in the file is 15:19. What's clearing the diag.txt so often? Is there a bug that it's not being appended to?

I've clicked OK to resume trading.
