Did anyone notice this too? Guy stepped up with 100K shares from 10.00 to 14.00 and nobody filled him, he just ended up cancelling. It happened after 9:30 but I'm not sure if it happened before or after the stock opened. If it happened after the stock opened, wouldn't an LRP prevent this from happening? If it happened before it opened, what the hell? How far away from the price does a trade get broken? Can premarket trades be broken? It was not a bad tick. I watched him step up. Never saw anything so wild before. But trading resumed as normal 2 minutes later as if nothing had happened.
