Construction Of The Individual Stock Trading System Based On RHadoop

Finance and investment become the way to make money in People’s Daily life, and the stock is definitely one of the high risk and high return one of the hottest investment ways, how to fully understand the stock movements, low risk has a substantial return as a hot research, especially in the modern era of the Internet has had the enormous influence on the development of the stock market, not only expanded the space of the stock market boundaries, and produced a large number of stock transaction data. In the face of vast amounts of data, no advanced computer technology as the auxiliary, it is difficult to understand the workings of the market and the analysis of their selected stock movements, so want to timely understand the market dynamic, steady income nor bedding bag, need to own the stock trading system from sasuke.R language is in statistics, R is established on the basis of the S language, in accordance with the GNU open source software, so born has strong ability of statistical computing and graphics, open source implementation of the toolkit to date more than 5200, make the fullest use of these kits, reasonable collocation is used, will greatly simplify the modeling process of our work, but the stand-alone version of R has many problems, the Internet age, data into exponentially, desired due to the large data problem, and restricts the R statistical analysis more accurate and faster ability; In terms of processing large data, Hadoop is one of the hot research, Hadoop makes terabytes and petabytes of storage, calculation, but although Hadoop can do according to the analysis of the full amount, but there is no data modeling, also does not have relevant certificates, predict the results will be a problem; In that case, R statistical analysis capabilities, combined with the Hadoop big data processing ability, just can be complementary and short-long; So, RHadoop appear to cater to the need of the market and the trend of the RHadoop contains three R package(RMR, RHDFS, rhbase), are respectively corresponding to the Hadoop system architecture of graphs, HDFS, HBase three parts. This article is using RHadoop open source software package R used combined with Hadoop. Based on various related open source in the R package, using R language program design, Hadoop HDFS system responsible for storing massive amounts of stock data, the two complement each other, to construct a system of stock trading.The main job of this paper: we installed Xen Server, virtualization, and build the Hadoop distributed environment in a Linux system, and then configured Hadoop related documents, the JDK installation configuration, eclipse, R software;Using RHadoop set R based on Hadoop distributed parallel programming environment, configuration files, for using R language graphs distributed program;Combining with the R language in various packages, build a complete trading system. The system includes: registration and login, get the trade data, visualization analysis, account management function and IBM(IBM) stock as an example for the system demonstration.
