I'm sure you know (hope) that T-Trades aren't trades, as such ... they're accounting mechanisms per the SEC to balance the MM's books. It's possible that a MM put on his little paper hat a little too soon on Friday before rushing out to meet his date at the farm for the big New Year's bash. Happy moo year. Also, being the start of a new trading year, it could have been a Monday accounting thing.

The most logical situation is that Brokers had to settle between themselves on shares that were "borrowed" during the day. So, if Broker A gets an order to Buy shares of a Stock that it does not have in its inventory it must borrow those shares from somewhere. Then the SEC gives them the responsibility to Close that deal within just a few minutes of the Market close. That is most normally what the T-trades mean.
