This is interesting from
the Telegraph:
Traders are using software developed by US-based technology StreamBase to monitor "tweets" for price sensitive information.
The software plugs into Algorithm-based automated trading platforms that have been used by traders for years. But rather than searching Reuters or Bloomberg the software now scans Twitter.com.
Streambase – whose client base includes Royal Bank of Canada and London-based hedge fund BlueCrest Capital Management – was commissioned to develop the software by several "unnamed" clients.
The software allows traders to take into account "event-based" information published on Twitter in their automated equity, bond and foreign exchange trading.
This interests me because it combines 2 streams of realtime value which up till now I thought separate, to wit realtime financial data and realtime consumer data.
