RE:Good luck to all longs.
Halts are to allow for the the dissemination of news that may be material to a firm's stock price during trading hours. Ergo ROI won't be halted for unknown news that might be 'expected' after the close.
Though doubtful, it also could be that there'll be a big bunch of secret orders that ROI will reveal after the close today. If that's the case the open tomorrow might be interesting.
