Design And Implementation Of ETF Terminal Based On.NET

Along with the rapid development of the socialist market economy and networkcommunication technology, the environment in which we live is filled with a variety offinancial products, for example, Stocks, Bonds, Insurances, ETF funds. All of them havetheir individual characteristics; the stocks become the long-term credit instruments in thecapital markets, because it has the characteristics, for example, it can be traded, can betransferred, or can be the price of mortgage. But the ETF(Exchange Traded Funds) Funds,which is a kind of transactional open fund and has a variable share, is popular all around theworld because of its smaller risk and stable rewards. Not only has the ETF Funds had thelower transaction costs, the higher transparency, but also the investors can arbitrage on thesame day. The investors can arbitrage the ETF funds by using the deviation between theactual transaction price in the actual transaction process and the NAV (Net Asset Value).The trading of the arbitrage will complete mainly through the cross-market trading of theETF, if the ETF meets the requirements, the investors will be able to buy the ETF sharesand redeem the corresponding basket of stocks in the secondary market, then sell them toarbitrage from the stock market.In the case of the recognition judgment scientific，people need to make use of programtrading tools to complete the ETF arbitrage. It is a kind of personalized trading, makes eachinvestor (or institution) can write their own trading model and use computer automatedtrading according to their investment experience and wisdom. Therefore, in view of thehigh demand of the people for the ETF arbitrage, this thesis designed and developed anprogram trading system accord with the needs of the user to help investors improve thespeed of ordering and realize the rational investment in actual combat.The terminal system uses c#language and.net framework to complete realization anduses a relational database management system SQL Server to record all kinds ofinformation. The system’s main design part will be introduced in the third chapter of thisarticle, mainly including the design of the database. The database is very large, so I onlyintroduce some of the more important relation table, etc.; it also includes the design of thefunction module, first of all I make a brief introduce about the whole system to realize eachfunction module，secondly about my main responsible ETF arbitrage module, I will make an introduction. Finally I will introduce some important module code realization.After the completion of the entire ETF terminal system analysis and designsuccessfully, I make application technology Coding.In the actual operation process I testand evaluate the system of the whole operation. I make a simple description about thewhole system function operation interface in the fourth chapter in this paper. For the keyfunction point, further follow-up. Strive to simulate the actual operation about the design ofETF terminal system in this topic in the real operation conditions.This paper introduces the concept of "program trading, the system we design hassimple upgrade, transplant, high security, low cost and personalized service maintenance,but because of the major limitations of knowledge and the limited capacity, the program’smain defect is that there is a time lag between reveals the arbitrage possibility of ETF"with " commission final completion, it can note avoided in theory, so it is prone to bias.We expect to do some expansion on the basis of the system: the PC platform to the mobileplatform transplantation, and to improve the stability of large traffic access.
