Abstract:
In a foreign currency exchange market, there are highdensity
data streams. The present approaches for
visualization of this type of data cannot show us a figure
with targeted both local details and global trend
information. In this paper, on the basis of features and
attributes of foreign currency exchange trading streams,
we discuss and compare multiple approaches including
interactive zooming, multiform sampling with
combination of attribute of large foreign currency
exchange data, and fish-eye view embedded visualization
for visual display of high-density foreign currency
exchange transactions. By comparison, Fish-eye-based
visualization is the best option, which can display
regional records in details without losing global
movement trend in the market in a limited display
window. We used Fish-eye technology for output
visualization of foreign currency exchange trading
strategies in our trading support system linking to realtime
foreign currency market closing data.
