re LCRE AH trades: Those trades (#528-531) were 'form T' trades - probably made much earlier in the day, but not settled until after 4pm
If you look at a 1 minute intraday chart you can see the big blocks between 10:30-11:00am - 3 of 4 of those trades were @ .0015 - (note: the chart shows .0016-.0013)
You can also read the volume data and see that they were included in the day's total.
All I can say is that if I were trading 1/10 the daily volume, I'd want to hide it too.
