I saw that FormT trade also - the problem is you can't tell if it was buy driven or sell driven.
FormTs typically occur when a client places a large order with a Broker/MM (either a sell, a short, a buy or a cover).
The Broker/MM executes the order in parts throughout the day as to not dramatically move the price in either direction, and then prints the final aggregate transaction as a FormT after hours.
The broker will take a few percent fee off the cost basis for himself and then settle with the client.
So in this case, the client could have initiated a sell, and the broker sold all of the shares averaged higher than 33.49, or the client could have initiated a buy, and the broker bought all of the shares averaged lowered than 33.49.
This could have also been a short or cover, which would have yielded a similar Form T.
