It is very likely that we will get another large T-trade today. The T-trade has to occur within the daily pps trading range. There was a lot of support yesterday and thus it took a lot of selling on the BID in order to get the pps in a range where the T-trade could be part of.
There is less BID support today and thus we may rebound quicker since the T-trade can now occur within the pps range that the MMs want.
I have no idea what is going on, but this is one thing that I have payed close attention to. We may see a green close with a huge T-trade today.
