Looking at the two minute chart here since Twitter active after-hours and my $9.99 data feed can only grab 500 bars ... didn't have the scanner running but assume it would have picked this one up. "Takeover target" rumor supposedly what drove it. Always interested to talk to the day traders who caught it (there are no day traders anymore).
StockTwits stream from the moment ... yes, once again, there's OpenOutcrier.
