REST vs WebSocket

REST与WebSocket对比

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

特性	REST API	WebSocket API
适用场景	一次性查询、下单	实时监控、实时价格推送
导入命名空间	`using ccxt;`	`using ccxt.pro;`
方法前缀	`Fetch*` （如FetchTicker、FetchOrderBook）	`Watch*` （如WatchTicker、WatchOrderBook）
速度	较慢（HTTP请求/响应模式）	更快（长连接模式）
请求限制	严格（1-2次请求/秒）	更宽松（持续流推送）
最佳用途	交易操作、账户管理	价格监控、套利检测

方法命名规范： C#使用PascalCase命名法 - 即

Checking Method Availability

检查方法可用性

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,
//   ...
// }

并非所有交易所都支持所有方法，使用前请检查：

// 检查方法是否支持
if (exchange.has['fetchOHLCV']) {
    const candles = await exchange.fetchOHLCV('BTC/USDT', '1h')
}

// 检查多个功能支持情况
console.log(exchange.has)
// {
//   fetchTicker: true,
//   fetchOHLCV: true,
//   fetchMyTrades: true,
//   fetchPositions: false,

Proxy Configuration

代理配置

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

CCXT支持HTTP、HTTPS和SOCKS代理，适用于REST和WebSocket连接。

Setting Proxy

设置代理

// 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'

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

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

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

// 带身份验证的代理
exchange.httpProxy = 'http://user:pass@proxy-host:port'

Proxy for WebSocket

WebSocket代理

WebSocket connections also respect proxy settings:

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

WebSocket连接同样会遵循代理设置：

exchange.httpsProxy = 'https://proxy:8080'
// WebSocket连接将使用此代理

Testing Proxy Connection

测试代理连接

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

exchange.httpProxy = 'http://localhost:8080'
try {
    await exchange.fetchTicker('BTC/USDT')
    console.log('代理连接正常！')
} catch (error) {
    console.error('代理连接失败:', error)
}

When to Use WebSocket Methods

何时使用WebSocket方法

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

当以下情况时使用
*Ws
方法：

你需要更快的下单速度（更低延迟）
你已经通过WebSocket连接到交易所
你想减少REST API的请求限制消耗
交易策略要求延迟低于100毫秒

当以下情况时使用REST方法：

你需要确保执行确认
你只需要进行一次性请求
交易所不支持对应的WebSocket变体方法
你需要详细的错误响应信息

Example: Order Placement Comparison

示例：下单方式对比

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)

REST API（速度较慢，可靠性更高）：

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

WebSocket API（速度更快，延迟更低）：

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

Checking WebSocket Method Availability

检查WebSocket方法可用性

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)
}

并非所有交易所都支持WebSocket交易方法：

if (exchange.has['createOrderWs']) {
    // 交易所支持通过WebSocket创建订单
    const order = await exchange.createOrderWs('BTC/USDT', 'limit', 'buy', 0.01, 50000)
} else {
    // 回退到REST方法
    const order = await exchange.createOrder('BTC/USDT', 'limit', 'buy', 0.01, 50000)
}

Authentication

身份验证

Setting API Keys

设置API密钥

csharp

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");

csharp

using System;

// 实例化时设置（推荐方式）
var exchange = new Binance
{
    ApiKey = Environment.GetEnvironmentVariable("BINANCE_API_KEY"),
    Secret = Environment.GetEnvironmentVariable("BINANCE_SECRET"),
    EnableRateLimit = true
};

// 实例化后设置
exchange.ApiKey = Environment.GetEnvironmentVariable("BINANCE_API_KEY");
exchange.Secret = Environment.GetEnvironmentVariable("BINANCE_SECRET");

Testing Authentication

测试身份验证

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

                await Task.Delay(1000 * (i + 1));  // 指数退避等待
            }
            else
            {
                throw;
            }
        }
    }
    return null;
}

Rate Limiting

请求限制

Built-in Rate Limiter (Recommended)

内置请求限制器（推荐）

csharp

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

csharp

var exchange = new Binance
{
    EnableRateLimit = true  // 自动限制请求频率
};

Manual Delays

手动延迟

csharp

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

csharp

await exchange.FetchTicker("BTC/USDT");
await Task.Delay((int)exchange.RateLimit);  // 请求之间添加等待
await exchange.FetchTicker("ETH/USDT");

Checking Rate Limit

查看请求限制

csharp

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

csharp

Console.WriteLine(exchange.RateLimit);  // 请求之间的等待间隔（毫秒）

Common Pitfalls

常见陷阱

Wrong Method Casing

方法命名大小写错误

csharp

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

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

csharp

// 错误写法 - 小写（JavaScript风格）
var ticker = await exchange.fetchTicker("BTC/USDT");  // 错误！

// 正确写法 - PascalCase（C#风格）
var ticker = await exchange.FetchTicker("BTC/USDT");

Not Awaiting Async Methods

未等待异步方法

csharp

// 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!

csharp

// 错误写法 - 缺少await
var ticker = exchange.FetchTicker("BTC/USDT");  // 返回Task，而非Ticker对象！
Console.WriteLine(ticker.Last);  // 错误！

// 正确写法
var ticker = await exchange.FetchTicker("BTC/USDT");
Console.WriteLine(ticker.Last);  // 正常运行！

Using REST for Real-time Monitoring

使用REST进行实时监控

csharp

// 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);
}

csharp

// 错误写法 - 浪费请求次数
while (true)
{
    var ticker = await exchange.FetchTicker("BTC/USDT");  // REST请求
    Console.WriteLine(ticker.Last);
    await Task.Delay(1000);
}

// 正确写法 - 使用WebSocket
using ccxt.pro;
var exchange = new Binance();
while (true)
{
    var ticker = await exchange.WatchTicker("BTC/USDT");  // WebSocket实时推送
    Console.WriteLine(ticker.Last);
}

Not Closing WebSocket Connections

未关闭WebSocket连接

csharp

// 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();
}

csharp

// 错误写法 - 内存泄漏
var exchange = new ccxt.pro.Binance();
var ticker = await exchange.WatchTicker("BTC/USDT");
// 忘记关闭连接！

// 正确写法
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

交易对格式错误

csharp

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

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

csharp

// 错误的交易对格式
"BTCUSDT"    // 错误 - 无分隔符
"BTC-USDT"   // 错误 - 使用短横线分隔
"btc/usdt"   // 错误 - 小写

// 正确的交易对格式
"BTC/USDT"   // CCXT统一格式

Troubleshooting

故障排除

Common Issues

常见问题

1. "Package CCXT.NET not found"

Solution: Run
```
dotnet add package CCXT.NET
```

2. "RateLimitExceeded"

Solution: Set
```
EnableRateLimit = true
```

3. "AuthenticationError"

Solution: Check API key and secret
Verify API key permissions on exchange
Check system clock is synced

4. "InvalidNonce"

Solution: Sync system clock
Use only one exchange instance per API key

5. "InsufficientFunds"

Solution: Check available balance (
```
balance["BTC"].Free
```
)
Account for trading fees

6. "ExchangeNotAvailable"

Solution: Check exchange status/maintenance
Retry after a delay

1. "未找到CCXT.NET包"

解决方案：执行
```
dotnet add package CCXT.NET
```

2. "RateLimitExceeded"

解决方案：设置
```
EnableRateLimit = true
```

3. "AuthenticationError"

解决方案：检查API密钥和密钥
验证API密钥在交易所的权限设置
检查系统时钟是否同步

4. "InvalidNonce"

解决方案：同步系统时钟
每个API密钥仅使用一个交易所实例

5. "InsufficientFunds"

解决方案：检查可用余额（
```
balance["BTC"].Free
```
）
考虑交易手续费

6. "ExchangeNotAvailable"

解决方案：检查交易所状态/维护公告
延迟后重试
