CoinEx.Net Conventions

This codebase uses CoinEx.Net for CoinEx cryptocurrency exchange access. Do not write raw HttpClient calls to CoinEx endpoints.

Client setup pattern

using CoinEx.Net;
using CoinEx.Net.Clients;

var restClient = new CoinExRestClient(options =>
{
    options.ApiCredentials = new CoinExCredentials("API_KEY", "API_SECRET");
});

For public market data only, no credentials are needed: new CoinExRestClient().

Result pattern

All methods return WebCallResult<T> for REST or CallResult<T> for WebSocket. Always check .Success before reading .Data:

var tickers = await restClient.SpotApiV2.ExchangeData.GetTickersAsync(new[] { "BTCUSDT" });
if (!tickers.Success) { /* tickers.Error */ return; }
var price = tickers.Data.First().LastPrice;

API surface

• restClient.SpotApiV2.{ExchangeData|Account|Trading}
• restClient.FuturesApi.{ExchangeData|Account|Trading}
• socketClient.SpotApiV2 for spot WebSocket subscriptions
• socketClient.FuturesApi for futures WebSocket subscriptions
• restClient.SpotApiV2.SharedClient and restClient.FuturesApi.SharedClient
• socketClient.SpotApiV2.SharedClient and socketClient.FuturesApi.SharedClient

Order placement

Spot order placement includes AccountType:

var order = await restClient.SpotApiV2.Trading.PlaceOrderAsync(
    "BTCUSDT", AccountType.Spot, OrderSide.Buy, OrderTypeV2.Limit,
    quantity: 0.001m, price: 50000m);

Futures order placement does not include AccountType:

var order = await restClient.FuturesApi.Trading.PlaceOrderAsync(
    "ETHUSDT", OrderSide.Buy, OrderTypeV2.Market, quantity: 0.01m);

WebSocket pattern

var socketClient = new CoinExSocketClient();
var sub = await socketClient.SpotApiV2.SubscribeToTickerUpdatesAsync(
    new[] { "BTCUSDT" },
    update => { /* update.Data.First().LastPrice */ });
if (!sub.Success) { /* sub.Error */ return; }

await socketClient.UnsubscribeAsync(sub.Data);
