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)

var exchange = new Binance(); while (true) { var ticker = await exchange.WatchTicker("BTC/USDT"); Console.WriteLine($"Last: {ticker.Last}"); } await exchange.Close();

Watching Order Book (Live Depth Updates)

var exchange = new Binance(); while (true) { var orderbook = await exchange.WatchOrderBook("BTC/USDT"); Console.WriteLine($"Best bid: {orderbook.Bids[0][0]}"); Console.WriteLine($"Best ask: {orderbook.Asks[0][0]}"); } await exchange.Close();

Watching Trades (Live Trade Stream)

var exchange = new Binance(); while (true) { var trades = await exchange.WatchTrades("BTC/USDT"); foreach (var trade in trades) { Console.WriteLine($"{trade.Price} {trade.Amount} {trade.Side}"); } } await exchange.Close();

Watching Your Orders (Live Order Updates)

var exchange = new Binance { ApiKey = "YOUR_API_KEY", Secret = "YOUR_SECRET" };

while (true) { var orders = await exchange.WatchOrders("BTC/USDT"); foreach (var order in orders) { Console.WriteLine($"{order.Id} {order.Status} {order.Filled}"); } } await exchange.Close();

Watching Balance (Live Balance Updates)

var exchange = new Binance { ApiKey = "YOUR_API_KEY", Secret = "YOUR_SECRET" };

while (true) { var balance = await exchange.WatchBalance(); Console.WriteLine($"BTC: {balance["BTC"].Total}"); } await exchange.Close();

Watching Multiple Symbols

var exchange = new Binance(); var symbols = new[] { "BTC/USDT", "ETH/USDT", "SOL/USDT" };

while (true) { var tickers = await exchange.WatchTickers(symbols); foreach (var kvp in tickers) { Console.WriteLine($"{kvp.Key}: {kvp.Value.Last}"); } } await exchange.Close();

Checking Method Availability

Not all exchanges support all methods. Check before using:

// Check if method is supported if (exchange.has['fetchOHLCV']) { const candles = await exchange.fetchOHLCV('BTC/USDT', '1h') }

// Check multiple capabilities console.log(exchange.has) // { // fetchTicker: true, // fetchOHLCV: true, // fetchMyTrades: true, // fetchPositions: false, // ... // }

Method Naming Convention

  • fetch*

  • REST API methods (HTTP requests)

  • watch*

  • WebSocket methods (real-time streams)

  • create*

  • Create new resources (orders, addresses)

  • cancel*

  • Cancel existing resources

  • edit*

  • Modify existing resources

  • set*

  • Configure settings (leverage, margin mode)

  • *Ws suffix - WebSocket variant (some exchanges)

Proxy Configuration

CCXT supports HTTP, HTTPS, and SOCKS proxies for both REST and WebSocket connections.

Setting Proxy

// HTTP Proxy exchange.httpProxy = 'http://your-proxy-host:port'

// HTTPS Proxy
exchange.httpsProxy = 'https://your-proxy-host:port'

// SOCKS Proxy exchange.socksProxy = 'socks://your-proxy-host:port'

// Proxy with authentication exchange.httpProxy = 'http://user:pass@proxy-host:port'

Proxy for WebSocket

WebSocket connections also respect proxy settings:

exchange.httpsProxy = 'https://proxy:8080' // WebSocket connections will use this proxy

Testing Proxy Connection

exchange.httpProxy = 'http://localhost:8080' try { await exchange.fetchTicker('BTC/USDT') console.log('Proxy working!') } catch (error) { console.error('Proxy connection failed:', error) }

WebSocket-Specific Methods

Some exchanges provide WebSocket variants of REST methods for faster order placement and management. These use the *Ws suffix:

Trading via WebSocket

Creating Orders:

  • createOrderWs

  • Create order via WebSocket (faster than REST)

  • createLimitOrderWs

  • Create limit order via WebSocket

  • createMarketOrderWs

  • Create market order via WebSocket

  • createMarketSellOrderWs

  • Sell market order via WebSocket

  • createStopLimitOrderWs

  • Stop-limit order via WebSocket

  • createStopMarketOrderWs

  • Stop-market order via WebSocket

  • createStopLossOrderWs

  • Stop-loss order via WebSocket

  • createTakeProfitOrderWs

  • Take-profit order via WebSocket

  • createTrailingAmountOrderWs

  • Trailing stop via WebSocket

  • createTrailingPercentOrderWs

  • Trailing stop % via WebSocket

  • createPostOnlyOrderWs

  • Post-only order via WebSocket

  • createReduceOnlyOrderWs

  • Reduce-only order via WebSocket

Managing Orders:

  • editOrderWs

  • Edit order via WebSocket

  • Cancel order via WebSocket (faster than REST)

  • cancelOrdersWs

  • Cancel multiple orders via WebSocket

  • cancelAllOrdersWs

  • Cancel all orders via WebSocket

Fetching Data:

  • fetchOrderWs

  • Fetch order via WebSocket

  • fetchOrdersWs

  • Fetch orders via WebSocket

  • fetchOpenOrdersWs

  • Fetch open orders via WebSocket

  • fetchClosedOrdersWs

  • Fetch closed orders via WebSocket

  • fetchMyTradesWs

  • Fetch your trades via WebSocket

  • fetchBalanceWs

  • Fetch balance via WebSocket

  • fetchPositionWs

  • Fetch position via WebSocket

  • fetchPositionsWs

  • Fetch positions via WebSocket

  • fetchPositionsForSymbolWs

  • Fetch positions for symbol via WebSocket

  • fetchTradingFeesWs

  • Fetch trading fees via WebSocket

When to Use WebSocket Methods

Use *Ws methods when:

  • You need faster order placement (lower latency)

  • You're already connected via WebSocket

  • You want to reduce REST API rate limit usage

  • Trading strategies require sub-100ms latency

Use REST methods when:

  • You need guaranteed execution confirmation

  • You're making one-off requests

  • The exchange doesn't support the WebSocket variant

  • You need detailed error responses

Example: Order Placement Comparison

REST API (slower, more reliable):

const order = await exchange.createOrder('BTC/USDT', 'limit', 'buy', 0.01, 50000)

WebSocket API (faster, lower latency):

const order = await exchange.createOrderWs('BTC/USDT', 'limit', 'buy', 0.01, 50000)

Checking WebSocket Method Availability

Not all exchanges support WebSocket trading methods:

if (exchange.has['createOrderWs']) { // Exchange supports WebSocket order creation const order = await exchange.createOrderWs('BTC/USDT', 'limit', 'buy', 0.01, 50000) } else { // Fall back to REST const order = await exchange.createOrder('BTC/USDT', 'limit', 'buy', 0.01, 50000) }

Authentication

Setting API Keys

using System;

// During instantiation (recommended) var exchange = new Binance { ApiKey = Environment.GetEnvironmentVariable("BINANCE_API_KEY"), Secret = Environment.GetEnvironmentVariable("BINANCE_SECRET"), EnableRateLimit = true };

// After instantiation exchange.ApiKey = Environment.GetEnvironmentVariable("BINANCE_API_KEY"); exchange.Secret = Environment.GetEnvironmentVariable("BINANCE_SECRET");

Testing Authentication

try { var balance = await exchange.FetchBalance(); Console.WriteLine("Authentication successful!"); } catch (AuthenticationError) { Console.WriteLine("Invalid API credentials"); }

Error Handling

Exception Hierarchy

BaseError ├─ NetworkError (recoverable - retry) │ ├─ RequestTimeout │ ├─ ExchangeNotAvailable │ ├─ RateLimitExceeded │ └─ DDoSProtection └─ ExchangeError (non-recoverable - don't retry) ├─ AuthenticationError ├─ InsufficientFunds ├─ InvalidOrder └─ NotSupported

Basic Error Handling

using ccxt;

try { var ticker = await exchange.FetchTicker("BTC/USDT"); } catch (NetworkError ex) { Console.WriteLine($"Network error - retry: {ex.Message}"); } catch (ExchangeError ex) { Console.WriteLine($"Exchange error - do not retry: {ex.Message}"); } catch (Exception ex) { Console.WriteLine($"Unknown error: {ex.Message}"); }

Specific Exception Handling

try { var order = await exchange.CreateOrder("BTC/USDT", "limit", "buy", 0.01, 50000); } catch (InsufficientFunds) { Console.WriteLine("Not enough balance"); } catch (InvalidOrder) { Console.WriteLine("Invalid order parameters"); } catch (RateLimitExceeded) { Console.WriteLine("Rate limit hit - wait before retrying"); await Task.Delay(1000); // Wait 1 second } catch (AuthenticationError) { Console.WriteLine("Check your API credentials"); }

Retry Logic for Network Errors

async Task<Ticker> FetchWithRetry(int maxRetries = 3) { for (int i = 0; i < maxRetries; i++) { try { return await exchange.FetchTicker("BTC/USDT"); } catch (NetworkError) { if (i < maxRetries - 1) { Console.WriteLine($"Retry {i + 1}/{maxRetries}"); await Task.Delay(1000 * (i + 1)); // Exponential backoff } else { throw; } } } return null; }

Rate Limiting

Built-in Rate Limiter (Recommended)

var exchange = new Binance { EnableRateLimit = true // Automatically throttles requests };

Manual Delays

await exchange.FetchTicker("BTC/USDT"); await Task.Delay((int)exchange.RateLimit); // Wait between requests await exchange.FetchTicker("ETH/USDT");

Checking Rate Limit

Console.WriteLine(exchange.RateLimit); // Milliseconds between requests

Common Pitfalls

Wrong Method Casing

// Wrong - lowercase (JavaScript style) var ticker = await exchange.fetchTicker("BTC/USDT"); // ERROR!

// Correct - PascalCase (C# style) var ticker = await exchange.FetchTicker("BTC/USDT");

Not Awaiting Async Methods

// Wrong - missing await var ticker = exchange.FetchTicker("BTC/USDT"); // Returns Task, not Ticker! Console.WriteLine(ticker.Last); // ERROR!

// Correct var ticker = await exchange.FetchTicker("BTC/USDT"); Console.WriteLine(ticker.Last); // Works!

Using REST for Real-time Monitoring

// Wrong - wastes rate limits while (true) { var ticker = await exchange.FetchTicker("BTC/USDT"); // REST Console.WriteLine(ticker.Last); await Task.Delay(1000); }

// Correct - use WebSocket using ccxt.pro; var exchange = new Binance(); while (true) { var ticker = await exchange.WatchTicker("BTC/USDT"); // WebSocket Console.WriteLine(ticker.Last); }

Not Closing WebSocket Connections

// Wrong - memory leak var exchange = new ccxt.pro.Binance(); var ticker = await exchange.WatchTicker("BTC/USDT"); // Forgot to close!

// Correct var exchange = new ccxt.pro.Binance(); try { while (true) { var ticker = await exchange.WatchTicker("BTC/USDT"); Console.WriteLine(ticker.Last); } } finally { await exchange.Close(); }

Incorrect Symbol Format

// Wrong symbol formats "BTCUSDT" // Wrong - no separator "BTC-USDT" // Wrong - dash separator "btc/usdt" // Wrong - lowercase

// Correct symbol format "BTC/USDT" // Unified CCXT format

Troubleshooting

Common Issues

  1. "Package CCXT.NET not found"
  • Solution: Run dotnet add package CCXT.NET
  1. "RateLimitExceeded"
  • Solution: Set EnableRateLimit = true
  1. "AuthenticationError"

  • Solution: Check API key and secret

  • Verify API key permissions on exchange

  • Check system clock is synced

  1. "InvalidNonce"

  • Solution: Sync system clock

  • Use only one exchange instance per API key

  1. "InsufficientFunds"

  • Solution: Check available balance (balance["BTC"].Free )

  • Account for trading fees

  1. "ExchangeNotAvailable"

  • Solution: Check exchange status/maintenance

  • Retry after a delay

Debugging

// Enable verbose logging exchange.Verbose = true;

// Check exchange capabilities Console.WriteLine(exchange.Has); // { // FetchTicker = true, // FetchOrderBook = true, // CreateOrder = true, // ... // }

// Check market information var market = exchange.Markets["BTC/USDT"];

// Check last request/response Console.WriteLine(exchange.LastHttpResponse); Console.WriteLine(exchange.LastJsonResponse);
