Arbitrage Detector with Alert System

Arbitrage is a trading strategy based on the purchase of a commodity such as foreign exchange. The trading is done in one market at a particular price while simultaneously trying to sell the commodity in another market at a higher price in order to gain profit with least possible risk. The people that are doing the arbitrage are known as arbitrageurs. This paper presents the initial development of an arbitrage system for foreign exchange to ease the arbitrageurs to do the trading. Foreign exchange or simply known as Forex is a trading of one currency with another currency. Currently, the arbitrageurs have to detect a possible arbitrage manually by looking at the foreign exchange rates at a daily basis. The system will read the latest foreign exchange rates daily and inform or alert the arbitrageurs if any possible arbitrage is detected. The system is also able to recognize specific countries that have possible arbitrage. Development of the system starts of with the study of foreign exchange rates and the regulations involved in buying and selling of currencies. Also, since the system relies on the exchange rates from several countries and the source of those rates come from the Internet, a study on how to effectively extract the data from HTML source code is also done. As for conclusion, the developed system will help the arbitrageurs to detect any possible arbitrage in the markets.
