This study follows the four stages of mathematical modeling: Questioning, modeling, verification and comparison, redefines the new method of financial technical analysis-similar curve method and gives two original new concepts-curve similarity and WP indicator, as well as the visually achieved key source mode. With SPSS software, it is obtained that the probabilities for the increasing function to gain the maximum and minimum WP values are, respectively 34.28 and 22.86% and those for the decreasing function to obtain the maximum and minimum WP values are, respectively 33.33 and 25.71%. The test results of the original WP expert system to the 4 management objectives, i.e., win rate, annual rate of return, net profit rate and annual number of transactions are, respectively 87.57, 75.70, 31.54 and 6,837.60. Compared with other 6 expert systems, the above results are optimal. Due to similar methods of financial technical analysis, the similar curve method can be applied to the analysis of all transactions.]]>Chen, L.,2010Huang, H.P. and P. Wang,2013Huang, H.P. and P.
