Advanced Trading Operations

For private trading operations, you'll need to provide your API keys from the exchange. CCXT handles authentication securely and provides a consistent interface for trading activities across all supported platforms.

Authentication and Private API Access

To access private endpoints, initialize the exchange with your API credentials:

const exchange = new ccxt.binance({
    apiKey: 'YOUR_API_KEY',
    secret: 'YOUR_SECRET_KEY',
    enableRateLimit: true,
});

Common Trading Operations

Error Handling and Best Practices

Proper error handling is crucial when working with cryptocurrency APIs. CCXT provides structured error classes to help you manage exceptions gracefully.

Common Error Types

Rate Limiting

CCXT includes built-in rate limiting to prevent exceeding exchange API limits. Always enable rate limiting when creating exchange instances:

const exchange = new ccxt.binance({ enableRateLimit: true });
