Rong Zeng Cao · Computer Knowledge and Technology · 2009
On the basis of analyzing high nonlinear properties of stock market and summarizing time-series data segmentation algorithm, a segmentation expression way of getting the edge point through slope is presented concerning stock time-series data, so is an eight-bit symbolization expression way taking time length and limit rules into consideration, according to the limit restriction of 10% domestic stock price , which is proved to be effective in showing the relationship between stock price change and time, followed by theoretical analysis and validated results.
