Build a common and generic API to interact with differents digital currency markets

Develop a single interface to interact with these differing market APIs For example, if I want to check the BitCoin Market from BTC-E and send bitcoin to my FOXBIT account, I would just need to do that: Market marketBitCoin = [login to view URL]([login to view URL], [login to view URL], [login to view URL]) [login to view URL]() Should return [login to view URL] [login to view URL]() Should return [login to view URL] [login to view URL]() Should return [login to view URL] Order lastOrder = [login to view URL]() [login to view URL]() Should return 620 if in the last transaction bitcoin wass selled by 620 dollars Market marketFoxbitBitCoin = [login to view URL]([login to view URL], [login to view URL], [login to view URL]) [login to view URL]( [login to view URL](), 1.6326 ) [login to view URL]() should return 1.6326(less transfer network fees) And so on. It should work for others markets as well. These are the market that I want to interact: [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] For each one of them should be a file to set up the private key You are free to choose the language to do that, but you should follow these generics interfaces below: interface Market { List<Order> getSellOrders() List<Order> getSellOrders() Currency getOriginCurrency() Currency getDestinyCurrency() Market getMarket() String getWalletAddress() //It get the OriginCurrency address to send funds void sendTo(String address, Double amount) //It will transfer the OriginCurrency Double getBalance()// It will get the OriginCurrency balance void sendBuyOrder(Double amount, Double prize) void sendSellOrder(Double amount, Double prize) void update() //Update all market values with the last ones void lastExecutedOrder(); List<Order> getPendingOrders() }; public Order { Type getType() Currency getCurrency() Double getAmount() Double Prize() }; public enum Type { BUY, SELL }; public enum Currency { BITCOIN, LITECOIN, ETHERIUM, MONEY }; public enum Market { BTCE, POLONIEX, MERCADOBITCOIN, BITCOINTOYOU, FOXBIT }; class MarketFactory ( public static Market getMarket(Market, Currency origin, Currency destiny) ) I will send you a bitbucket invitation to upload the source code
