 prototype 2 project:

Modify prototype 1 for a user who is involved in trading currencies based on the trend of several exchange rate of a particular currency in the hope that the user will have profit if you buy the currency now and exchange the currency later in the future. The user speculates that the exchange rate of the target currency will increase in value in the future and so you gain a profit if you exchange the currency back to USD. Develop both in Android and iOS platforms.
