Many companies have to work across currencies. BigPay operates in both Malaysia and Singapore, and has to use an external service provider to move money between the two. It would be more efficient to do this themselves, managing reserves of both currencies (MYR and SGD), setting an exchange rate, and executing and settling transfers taking at least a day to complete. Your job is to design a software system capable of managing and visualising these reserves. It should take a feed of the buy and sell rates available from partners at various distances in time (1 day, 7 day, 30 day) and export an API allowing users to give a target currency and amount and receive a price (and then confirm the transfer). As far as possible, the system should achieve optimal revenue. You will need to write a simulator for exchange rates and for customer behaviour.
