#Trading Bitcoins using Mt.Gox API v2 This is a simple java client that uses the new Mt.Gox API (V2). The API are not well documented and this libraries are still unstable. I must say thank you to nitrous which is putting effort in documenting the v2 here.

Disclaimer: This codebase is under development. Use it at your own risk

#Get the sources Clone the repository with git (git clone https://github.com/adv0r/mtgox-api-v2-java.git) or download the zipped archive

#Sample project You can play around by opening your IDE (Netbeans, Eclipse, Sublime) and importing the zipped sample project (JRE >7)

#Setup First setup the java trustStore adding mtgox certificates. Basically you neet to tell to the JVM to trust mtgox's public certificate. I generated an encrypted keystore under res/ssl/mtgox.jks.

System.setProperty("javax.net.ssl.trustStore","res/ssl/mtgox.jks");
System.setProperty("javax.net.ssl.trustStorePassword","h4rdc0r_"); //I encripted the jks file using this pwd

Create an object encapsulating your API keys :

ApiKeys keys = new ApiKeys("your-secret-key", "your-api-key"); 

Create the interface for trading on Mtgox, passing the apikeys object

MtGox trade = new MtGox(keys);
//trade.setPrintHTTPResponse(true); //Uncomment this line to print the HTTP responses.

#Usage See the example class for a working demo.

Print the current price of BTC in USD and EUR. This functions use the undocumented ticker_fast function.

System.out.println("Current price of 1 BTC : \n" +
               "   "+trade.getLastPriceUSD()+" $\n"+
               "   "+trade.getLastPriceEUR()+" €");

Print the current balance from your MtGox account in USD,EUR, and BTC

System.out.println("Current account balance : \n" +
              "   "+trade.getBalance()[0]+" BTC\n"+
              "   "+trade.getBalance()[1]+" $\n"+
              "   "+trade.getBalance()[2]+" €");

Print the trading engine lag as a String

System.out.println("Current Lag : "+ trade.getLag());

Buy 0.1 BTC at market price

String buyResult = trade.buyBTC(0.1);
System.out.println(buyResult);

Sell 0.1 BTC at market price

String sellResult = trade.sellBTC(0.1);
System.out.println(sellResult);

Withdraw 0.1 BTC from your mtgox to a wallet address (mine)

trade.withdrawBTC(0.1, "1N7XxSvek1xVnWEBFGa5sHn1NhtDdMhkA7")

I'll be more than happy if you decide to test the above instruction ;) Indeed, by executing the code above you will donate 0.1 BTC to support my effort in completing this trading API. Feel free to integrate this library into your project. If you get rich (or if you design some trading algorithm to get rich) , let me know ;).

#Love it
