User's Guide

Using this client is as simple as instantiating a new PoloniexExchangeService with your Poloniex API Key and API Secret as constructor parameters:

String apiKey = "foo";
String apiSecret = "bar";
PoloniexExchangeService service = new PoloniexExchangeService(apiKey, apiSecret);

Passing in null (or invalid values) for either the API Key or API Secret will prevent you from successfully calling the Poloniex Trading API methods (trading, retrieving private info related to your account, etc), but public API methods will still work.

The PoloniexExchangeService offers the following functionality:

Public API Methods (does not require Poloniex account)

                        ZonedDateTime.now(ZoneOffset.UTC).minusDays(1).toEpochSecond());

Lending APIs

Active loans

String apiKey = "foo";
String apiSecret = "bar";
PoloniexLendingService service = new PoloniexLendingService(apiKey, apiSecret);
PoloniexActiveLoanTypes activeLoans = service.returnActiveLoans();

Create a loan offer

String apiKey = "foo";
String apiSecret = "bar";
PoloniexLendingService service = new PoloniexLendingService(apiKey, apiSecret);

BigDecimal amount = new BigDecimal("0.01"); 
BigDecimal lendingRate = new BigDecimal("0.0042"); // 0.42%
int duration = 3; // 2 ~ 60
PoloniexLendingResult result = service.createLoanOffer("BTC", amount, lendingRate, duration, true);

Return open loan offers

String apiKey = "foo";
String apiSecret = "bar";
PoloniexLendingService service = new PoloniexLendingService(apiKey, apiSecret);
List<PoloniexLoanOffer> list = service.returnOpenLoanOffers("BTC");

Create loan offer

String apiKey = "foo";
String apiSecret = "bar";
PoloniexLendingService service = new PoloniexLendingService(apiKey, apiSecret);

BigDecimal amount = new BigDecimal("0.01"); 
BigDecimal lendingRate = new BigDecimal("0.0042"); // 0.42%
int duration = 3; // 2 ~ 60
PoloniexLendingResult result = service.createLoanOffer("BTC", amount, lendingRate, duration, true);

Cancel loan offer

String apiKey = "foo";
String apiSecret = "bar";
PoloniexLendingService service = new PoloniexLendingService(apiKey, apiSecret);

PoloniexLendingResult result = service.cancelLoanOffer("49375906");

Toggle auto renew

String apiKey = "foo";
String apiSecret = "bar";
PoloniexLendingService service = new PoloniexLendingService(apiKey, apiSecret);

PoloniexLendingResult result = service.toggleAutoRenew("8654331");

Lending Histories

String apiKey = "foo";
String apiSecret = "bar";
PoloniexLendingService service = new PoloniexLendingService(apiKey, apiSecret);

// Weekly Report
List<PoloniexLendingHistory> lendingHistories = service.returnLendingHistory(24 * 7, 5000);
BigDecimal sum = BigDecimal.ZERO;
for (PoloniexLendingHistory h : lendingHistories)
{
  BigDecimal earned = h.earned;
  sum = sum.add(earned);
}

Websocket Interface

Using Poloniex's websocket interface is also very simple. The following example sets up subscriptions to the general ticker as well as the USDT_ETH order book / trades, and then runs for 60 seconds:

try (WSSClient wssClient = new WSSClient(ENDPOINT_URL)) {
            wssClient.addSubscription(PoloniexWSSSubscription.USDT_ETH, new LoggerMessageHandler());
            wssClient.addSubscription(PoloniexWSSSubscription.TICKER, new TickerMessageHandler());
            wssClient.run(60000);
}

To setup your own subscription handler, just implement the IMessageHandler interface and do your logic within the public void handle(String message) method.
