The trade of 165,000 mentioned by Lucy earlier was actually a partial fill of an order for 300,000 shares placed at 14:39:44 and completed 3 minutes and 43 seconds later at 14:42:27 It took 5 "partials" to satisfy the order.
So in reality, there were only two "trades" today; the one above and the "signal trade" later on at 15:09.
