ccxt-csharp

name ccxt-csharp description CCXT cryptocurrency exchange library for C# and .NET developers. Covers both REST API (standard) and WebSocket API (real-time). Helps install CCXT, connect to exchanges, fetch market data, place orders, stream live tickers/orderbooks, handle authentication, and manage errors in .NET projects. Use when working with crypto exchanges in C# applications, trading systems, or financial software. Supports .NET Standard 2.0+. CCXT for C# A comprehensive guide to using CCXT in C# and .NET projects for cryptocurrency exchange integration. Installation Via NuGet Package Manager dotnet add package CCXT.NET Or via Visual Studio: Right-click project → Manage NuGet Packages Search for "CCXT.NET" Click Install Requirements .NET Standard 2.0 or higher .NET Core 2.0+ / .NET 5+ / .NET Framework 4.6.1+ Quick Start REST API using ccxt; var exchange = new Binance(); await exchange.LoadMarkets(); var ticker = await exchange.FetchTicker( "BTC/USDT" ); Console.WriteLine(ticker); WebSocket API - Real-time Updates using ccxt.pro; var exchange = new Binance(); while ( true ) { var ticker = await exchange.WatchTicker( "BTC/USDT" ); Console.WriteLine(ticker.Last); // Live updates! } await exchange.Close(); REST vs WebSocket Feature REST API WebSocket API Use for One-time queries, placing orders Real-time monitoring, live price feeds Import using ccxt; using ccxt.pro; Methods Fetch* (FetchTicker, FetchOrderBook) Watch* (WatchTicker, WatchOrderBook) Speed Slower (HTTP request/response) Faster (persistent connection) Rate limits Strict (1-2 req/sec) More lenient (continuous stream) Best for Trading, account management Price monitoring, arbitrage detection Method naming: C# uses PascalCase - FetchTicker not fetchTicker , WatchTicker not watchTicker Creating Exchange Instance REST API using ccxt; // Public API (no authentication) var exchange = new Binance { EnableRateLimit = true // Recommended! }; // Private API (with authentication) var exchange = new Binance { ApiKey = "YOUR_API_KEY" , Secret = "YOUR_SECRET" , EnableRateLimit = true }; WebSocket API using ccxt.pro; // Public WebSocket var exchange = new Binance(); // Private WebSocket (with authentication) var exchange = new Binance { ApiKey = "YOUR_API_KEY" , Secret = "YOUR_SECRET" }; // Always close when done await exchange.Close(); Common REST Operations Loading Markets // Load all available trading pairs await exchange.LoadMarkets(); // Access market information var btcMarket = exchange.Market( "BTC/USDT" ); Console.WriteLine(btcMarket.Limits.Amount.Min); // Minimum order amount Fetching Ticker // Single ticker var ticker = await exchange.FetchTicker( "BTC/USDT" ); Console.WriteLine(ticker.Last); // Last price Console.WriteLine(ticker.Bid); // Best bid Console.WriteLine(ticker.Ask); // Best ask Console.WriteLine(ticker.Volume); // 24h volume // Multiple tickers (if supported) var tickers = await exchange.FetchTickers( new [] { "BTC/USDT" , "ETH/USDT" }); Fetching Order Book // Full orderbook var orderbook = await exchange.FetchOrderBook( "BTC/USDT" ); Console.WriteLine(orderbook.Bids[ 0 ]); // [price, amount] Console.WriteLine(orderbook.Asks[ 0 ]); // [price, amount] // Limited depth var orderbook = await exchange.FetchOrderBook( "BTC/USDT" , 5 ); // Top 5 levels Creating Orders Limit Order // Buy limit order var order = await exchange.CreateLimitBuyOrder( "BTC/USDT" , 0.01 , 50000 ); Console.WriteLine(order.Id); // Sell limit order var order = await exchange.CreateLimitSellOrder( "BTC/USDT" , 0.01 , 60000 ); // Generic limit order var order = await exchange.CreateOrder( "BTC/USDT" , "limit" , "buy" , 0.01 , 50000 ); Market Order // Buy market order var order = await exchange.CreateMarketBuyOrder( "BTC/USDT" , 0.01 ); // Sell market order var order = await exchange.CreateMarketSellOrder( "BTC/USDT" , 0.01 ); // Generic market order var order = await exchange.CreateOrder( "BTC/USDT" , "market" , "sell" , 0.01 ); Fetching Balance var balance = await exchange.FetchBalance(); Console.WriteLine(balance[ "BTC" ].Free); // Available balance Console.WriteLine(balance[ "BTC" ].Used); // Balance in orders Console.WriteLine(balance[ "BTC" ].Total); // Total balance Fetching Orders // Open orders var openOrders = await exchange.FetchOpenOrders( "BTC/USDT" ); // Closed orders var closedOrders = await exchange.FetchClosedOrders( "BTC/USDT" ); // All orders (open + closed) var allOrders = await exchange.FetchOrders( "BTC/USDT" ); // Single order by ID var order = await exchange.FetchOrder(orderId, "BTC/USDT" ); Fetching Trades // Recent public trades var trades = await exchange.FetchTrades( "BTC/USDT" , limit: 10 ); // Your trades (requires authentication) var myTrades = await exchange.FetchMyTrades( "BTC/USDT" ); Canceling Orders // Cancel single order await exchange.CancelOrder(orderId, "BTC/USDT" ); // Cancel all orders for a symbol await exchange.CancelAllOrders( "BTC/USDT" ); WebSocket Operations (Real-time) Watching Ticker (Live Price Updates) using ccxt.pro;
