RE: 1.40-1.60 today17 Feb 2023 12:21
I'm not saying that that doesn't occur Hardcore1.......!
but in this instance, it was just one of the standard auctions throughout the day.........! :)
Ten mins to 08:00, 09:00, 11:00 (in this case), 14:00 and then on close of book at 16:30.
The extension would've been caused by a mismatch on the buy 'n sell orders causing it to be extended by 5mins twice.......!
All the best (result was the UT 10mins late)
