Abstract
This paper demonstrates an opinion indicator (OI)
generation system, named Crowd View, with which
traders can refer to the fine-grained opinions, beyond the market sentiment (bullish/bearish), from
crowd investors when trading financial instruments.
We collect the real-time textual information from
Twitter, and convert it into five kinds of OIs, including the support price level, resistance price level,
price target, buy-side cost, and sell-side cost. The
OIs for all component stocks in Dow Jones Industrial Average Index (DJI) are provided, and shown
with the real-time stock price for comparison and
analysis. The information embedding in the OIs
and the application scenarios are introduced
