Problem statement

Create a report that shows Amount in USD settled incoming every day Amount in USD settled outgoing every day Ranking of entities based on incoming and outgoing amount. Eg: If entity foo instructs the highest the amount for a buy instruction, then foo is rank 1 for outgoing

Application implementation

The starting Point of the Aplication is Application.java Interface TradeSettlement which defines settleTransaction() method and is implemented by below classes. The Two classes OutgoingSettlement and IncomingSettlement contains the code to for incoming and outgoing trade functionalities. CSVReader reads the file and populates the entity object model. Entity object model contains the parameters as per the datafile. TradeParams conatins the trade related constraints and implementations Ex Validating working day. SettlementConstants defines the constant configurable properties.

To generate Amount in USD settled incoming everyday

Class IncomingSettlement overridden method settle Transaction to populate the tradeMap. Method settleTrasaction() calls CSVFileReader.readFile() method to read the file. Method readFile() reads the file stream and calls addEntity Method to generate and add the entity to the entityList. Method addEntity() split the stream(EntityDetails) by the INSTRUCTION_FILE_SEPERATER and sets each param. Param settlementDate is processed via TradeParams.getWorkingDay() method TradeParams defines the Map which assigns numerical values to the week days. getWorkingDay() check the workingday status as per currency and current day. getWorkingDay() returns 0 if the Day of settlement date is working day or 1 or 2 (days to be added) to calculate next working day. Param USD is calculated as per requirment Price per unit * Units * AgreedFx

After tradeMap is populated get the map via getTradeMap() and print the result

TO generate Amount in USD settled outgoing everyday

Above is implemented with class OutgoingSettlement

Ranking of entities

To generate the ranking for incoming and outgoing ,call the respective class's getRankMap() method which sorts the rankMap generated settleTrasaction() method and print the rankings

Error Handing

If the data is null or empty in a particular line ,the code prints Data invaild or "Invaild Entity skipped :" in the output with entity details

If the data is invalid like invaild data type or wrong format the application will continue and print the invaild entity with exception and Error message.

DataFlile

Data file is kept at the src/resource location and is considered as a CSV file with header.

Assumption

The code currenlty considers settlement date for both incoming and outgoing settlements
