The exchange rate is the rate at which one currency will be exchanged for another. It is also regarded as the value of one country's currency in relation to another currency. Exchange rates are determined in the foreign exchange market, which is open to a wide range of different types of buyers and sellers, and where currency trading is continuous: 24 hours a day except weekends. The spot exchange rate refers to the current exchange rate. The forward exchange rate refers to an exchange rate that is quoted and traded today but for delivery and payment on a specific future date.

This app uses machine learning to predict currency exchange rate per 1 USD. The three most traded currencies by value (EUR, JPY, and GBP) are used as predictor features. Preprocessing of exchange rate training data is undertaken using Python. Machine learning toolset 'CreateML' is used to fit a model to training data.
