Different countries use different currencies, and there is daily variation in these countries relative to one another. Those who transfer money from one country to another (one currency to another)must be updated with the latest currency exchange rates in the market. Such application can be used by any user, but it is mainly useful for business, shares, and finance related areas where money transfer and currency exchange takes place on a daily basis.

CURRENCY CONVERTER OBJECTIVE Currency converter aims to maintain real time information on current market or bank exchange rates, so that the calculated result changes whenever the value of either of the component currencies does and also it rectifies the error while converting large values from distinct currencies.

Figure 1.1 Currency Converter

INTRODUCTION A currency converter is software code that is designed to convert one currency into another in order to check its corresponding value. In order to convert one currency into another, a user enters an amount of money (e.g. '1000') and chooses the currency he/she wishes to check the monetary value of (e.g. 'United States Dollar'). After that, the user selects one, or sometimes several other currencies, he/she would like to see the result in. The application software then calculates and displays the corresponding amount of money.

LITERATURE SURVEY 1. A paper naming “Method and system for delivering foreign exchange risk management” was done by Lois Scheirer and it was published in Dec 2001. In this paper they suggest a Consistent with principles of the present invention, a method and system for delivering foreign exchange risk management advisory solutions to a designated marked is disclosed. For each user, the disclosed system generates an exposure model that is consistent with that user's risk management policy and a budget/pricing determination made in response to user information and external pricing information. 2. A paper naming “System and method for generating and executing foreign exchange losses” was published in Oct 2000. The authors were Jay S. Walker, James A. Jorasch In this paper they suggest a system and method for providing a foreign exchange insurance policy that automatically considers factors such as the type of currency, exchange rate, amount of coverage, and period of coverage, to determine a premium. Users can access the system using credit cards, ATMs, banks or other media. 3. A paper naming “Algorithmic Trading in the Foreign Exchange Market” was published in Sept 2014. The authors were Alain P.Chaboud, Benjamin Chiquoine, Erik Hjalmarsson and Clara Vega. In this paper they suggest the impact of algorithmic trading (AT) in the foreign

exchange market using a long time series of hi gh-

frequency data that identifycomputer-generated trading activity. We find that AT causes an improvement in two measures of price efficiency: the frequency of triangular arbitrage opportunities and the autocorrelation of high-frequency returns. 3

4. The paper naming “Foreign Exchange Trading in Emerging Currencies : More Financial,

More Offshore” was published in March 2011. Authors were

Robert N. McCauley, Michela Scatigna. In this paper they suggest Foreign exchange turnover evolves in a predictable fashion with increasing income. As income per capita rises, currency trading cuts loose from underlying current account transactions. In parallel, an increasing share of trading in the currency takes place outside the home country. At given income levels, moreover, currencies with either high or very low yields attract more trading, consistent with their role as target and funding currencies in carry trades.

5.

Paper naming “Foreign exchange transaction system” was published in Nov 2009. Author was Sholom S.Rosen. In this paper he suggest A realtime multilateral foreign exchange settlement system having a computer implemented netting system, a processorbased multilateral settlement coordinator (MSC) having a first money module and a first host application, where the first host application receives debit and credit data from said netting system. A plurality of processor-based multilateral settlement agents (MSAs) each having a second money module and a second host application.

EXISTING SYSTEM The existing system consists of exchange of currencies from one country to another. However during transaction the large amount cannot be exchanged to the foreign currencies there occurs an error during transaction.

PROBLEMS IDENTIFIED This currency converter system shows errors while converting large values from distinct currencies that vary a lot and are not usually converted into each other.

PROPOSED SYSTEM This software system uses efficient algorithms to easily and instantly convert one currency to other and it also rectifies the error that occurs while converting large values from distinct currencies.

MODULES DESCRIPTION

1. CHOOSING THE CURRENCY TYPE:

The webpage asks the user to choose the currency type from the given currency option. The user can convert the currency from Euro to USD, USD to Euro and Pounds to USD. 2. ENTER THE CURRENCY VALUE

It asks for the user to enter the currency value that is to be changed from one currency to another. If the entering current value is in negative, there it displays please enter the positive values 3. MULTIPLIES THE VALUE:

Once the user enters the value, it performs the multiplication operation according to the currency values that has to be changed further. Each converting currency values performs different multiplication operation. 4. PRINTING THE VALUE:

After the process is over then it prints the converted currency values according to the user required.

CONCLUSION Currency converter that the people are using, they will always find ways to get the highest possible profits out of the exchanges. To those who are going to travel, it is a wise thing to check the different foreign exchange options they have beforehand.
