RE: Sudden spike to 578.8 today?11 Mar 2024 20:48
It looks like a typo - someone entering a trade price of 578.8 in error and then it would be immediately cancelled and replaced with the correct trade at 548.8, all timed the exact same when the trade was published. I can't confirm that 100% as the stock exchange list for some reason never seems to show the deleted trade when this happens, it just shows 2 x 10,000 trades at those two prices recorded with the exact same time. And, frustratingly, the Morningside trade list I can see only goes back to 43 seconds/3 trades after the trade time for this and they would normally show the deletion otherwise. Would need someone with Level 2 access on here to confirm the deletion from the extended list.
But it happens fairly often, known as a 'fat finger entry' in the biz (4 and 7 next to each other on the keyboard), so I'm 99% certain that's the likely explanation.
