Not really - unless you know from personal experience. The traders would have (or at least should have) been selling earlier in the day after the long awaited PR turned out to be exactly NOTHING to the share price, as some of us expected. The traders see the bottom falling out (LVL2 was pretty clear we were weak) and put buys in lower to catch the falling knife.
That's how I used to do it, and many other people I know did the same thing. It's a simple and easy to execute play.
Quite a nice little adjustment in average cost per share when done properly. Congrats to those that played the PR.
