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.
