RE: 6 price monitoring extensions now26 Jun 2020 16:00
Robrob they are issued when the uncrossing trade (UT) is going to be more than a certain % away from the current price. It causes the auctions which occur at specific times each day to be extended by another 5 minutes which can happen at most twice per auction. Usually on this stock the trades/orders involved are tiny and presumably it's just traders with DMA messing around.
In summary, it tells you nothing.
