How to use

Basic request:

// Get the ETH/USDT ticker via rest request
var restClient = new BitMartRestClient();
var tickerResult = await restClient.SpotApi.ExchangeData.GetTickerAsync("ETH_USDT");
var lastPrice = tickerResult.Data.LastPrice;

Place order:

var restClient = new BitMartRestClient(opts => {
	opts.ApiCredentials = new BitMartCredentials("APIKEY", "APISECRET", "PASS");
});

// Place Limit order to go long for 10 contracts ETH/USDT at 2000
var orderResult = await restClient.UsdFuturesApi.Trading.PlaceOrderAsync(
    "ETHUSDT",
    FuturesSide.BuyOpenLong,
    FuturesOrderType.Limit,
    10,
    2000);

WebSocket subscription:

// Subscribe to ETH/USDT ticker updates via the websocket API
var socketClient = new BitMartSocketClient();
var tickerSubscriptionResult = socketClient.SpotApi.SubscribeToTickerUpdatesAsync("ETH_USDT", (update) => 
{
  var lastPrice = update.Data.LastPrice;
});

CryptoExchange.Net

BitMart.Net is based on the CryptoExchange.Net base library. Other exchange API implementations based on the CryptoExchange.Net base library are available and follow the same logic.

CryptoExchange.Net also allows for easy access to different exchange API's.
