How to predict the stock price more accurately is the key concern of researchers and investors. To solve the above problems, this paper proposes an Informer based method for stock intraday price prediction. Informer based on attention mechanism can efficiently capture precise long-range dependencies between input and output to increase the prediction capacity. In this research, historical K-line data of traditional securities in China\u2019s financial market are collected. Based on this data set, the intraday stock price prediction performance of Informer and Long Short-Term Memory neural network (LSTM) is compared. The experiment also uses the three-day K-line model to perform pattern recognition on the K-line data of candidate stocks. The results show that the prediction performance of Informer is significantly higher than that of LSTM, and the data information after three-day K-line pattern recognition can improve the prediction accuracy of Informer and reduce time and space overhead of Informer. <\/jats:p>","DOI":"10.1142\/s1469026824420021","type":"journal-article","created":{"date-parts":[[2024,11,25]],"date-time":"2024-11-25T01:20:21Z","timestamp":1732497621000},"source":"Crossref","is-referenced-by-count":6,"title":["Informer-Based Method for Stock Intraday Price Prediction"],"prefix":"10.1142","volume":"24","author":[{"given":"Chen","family":"Zhang","sequence":"first","affiliation":[{"name":"Software College, Northeastern University, No. 195 Chuangxin Road, Hunnan District, Shenyang 110169, P.\u00a0R.\u00a0China"}]},{"given":"Yu","family":"Sun","sequence":"additional","affiliation":[{"name":"Software College, Northeastern University, No. 195 Chuangxin Road, Hunnan District, Shenyang 110169, P.\u00a0R.\u00a0China"}]},{"given":"Ying","family":"Ding","sequence":"additional","affiliation":[{"name":"Software Development Center Department, Haitong Securities Co., Ltd., No. 888 Zhongshan South Road, Huangpu District, Shanghai 200011, P.\u00a0R.\u00a0China"}]},{"given":"Jiaxu","family":"Ning","sequence":"additional","affiliation":[{"name":"School of Information Science and Engineering, Shenyang Ligong University, No. 6 Nanping Middle Road, Hunnan District, Shenyang 110159, P.\u00a0R.\u00a0China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8058-9809","authenticated-orcid":false,"given":"Changsheng","family":"Zhang","sequence":"additional","affiliation":[{"name":"Software College, Northeastern University, No. 195 Chuangxin Road, Hunnan District, Shenyang 110169, P.\u00a0R.\u00a0China"}]}],"member":"219","published-online":{"date-parts":[[2024,11,25]]},"reference":[{"key":"S1469026824420021BIB001","doi-asserted-by":"publisher","DOI":"10.1016\/j.ins.2022.03.064"},{"key":"S1469026824420021BIB002","doi-asserted-by":"publisher","DOI":"10.1016\/j.ins.2020.12.068"},{"key":"S1469026824420021BIB003","doi-asserted-by":"publisher","DOI":"10.1109\/JAS.2021.1003976"},{"key":"S1469026824420021BIB004","first-page":"3","volume":"10","author":"Al Rimawi M.
