Design Principles

• Single Responsibility - Each service handles a specific domain
• Dependency Injection - HTTP client injected for testability
• Functional Options - Flexible client configuration
• Error Transparency - Rich error types for debugging
• Immutability - Thread-safe by design

---

Installation

• Go 1.21+
• BingX account with API keys (for authenticated endpoints)

go get github.com/tigusigalpa/bingx-go

Only external dependency: github.com/gorilla/websocket (for WebSocket features)

Response Format

All API methods return (map[string]interface{}, error):

response, err := client.Market().GetLatestPrice("BTC-USDT")
if err != nil {
    // Handle error
}

// Access response data
if data, ok := response["data"].(map[string]interface{}); ok {
    price := data["price"]
    fmt.Printf("Price: %v\n", price)
}

Error Handling

import "github.com/tigusigalpa/bingx-go/errors"

// Handle errors
order, err := client.Trade().CreateOrder(params)
if err != nil {
    switch e := err.(type) {
    case *errors.AuthenticationException:
        log.Printf("Authentication error: %v", e)
    case *errors.RateLimitException:
        log.Printf("Rate limit exceeded: %v", e)
    case *errors.InsufficientBalanceException:
        log.Printf("Insufficient balance: %v", e)
    case *errors.APIException:
        log.Printf("API error [%s]: %v", e.APICode, e)
    default:
        log.Printf("Error: %v", err)
    }
    return
}

Error Types

• BingXException - Base exception for all errors
• APIException - API-level errors with error codes
• AuthenticationException - Authentication failures
• RateLimitException - Rate limit exceeded
• InsufficientBalanceException - Insufficient balance errors

Best Practices

Security

// DO: Use environment variables for credentials
apiKey := os.Getenv("BINGX_API_KEY")
apiSecret := os.Getenv("BINGX_API_SECRET")

// ❌ DON'T: Hardcode credentials
apiKey := "your_api_key_here" // Never do this!

// ✅ DO: Restrict API key permissions
// Only enable permissions you need (read-only for monitoring, etc.)

// ✅ DO: Use IP whitelist
// Configure IP restrictions in BingX API settings

Error Handling

// ✅ DO: Always check errors
result, err := client.Trade().CreateOrder(params)
if err != nil {
    // Handle specific error types
    switch e := err.(type) {
    case *errors.RateLimitException:
        // Implement exponential backoff
        time.Sleep(time.Second * 5)
    case *errors.InsufficientBalanceException:
        // Log and alert
        log.Error("Insufficient balance")
    default:
        // Generic error handling
        log.Error(err)
    }
    return
}

// ❌ DON'T: Ignore errors
result, _ := client.Trade().CreateOrder(params) // Bad practice

Performance

// ✅ DO: Reuse client instances
var globalClient *bingx.Client

func init() {
    globalClient = bingx.NewClient(apiKey, apiSecret)
}

// ❌ DON'T: Create new client for each request
func makeRequest() {
    client := bingx.NewClient(apiKey, apiSecret) // Wasteful
    client.Market().GetLatestPrice("BTC-USDT")
}

// ✅ DO: Use batch operations when possible
orders := []map[string]interface{}{...}
client.Trade().CreateBatchOrders(orders)

// ❌ DON'T: Make individual requests in loops
for _, order := range orders {
    client.Trade().CreateOrder(order) // Inefficient
}

Concurrency

// ✅ DO: Client is thread-safe
var wg sync.WaitGroup
for _, symbol := range symbols {
    wg.Add(1)
    go func(s string) {
        defer wg.Done()
        price, _ := client.Market().GetLatestPrice(s)
        // Process price
    }(symbol)
}
wg.Wait()

Testing

Unit testing

package main

import (
    "testing"
    bingx "github.com/tigusigalpa/bingx-go"
)

func TestMarketData(t *testing.T) {
    client := bingx.NewClient("", "") // Empty credentials for public endpoints
    
    symbols, err := client.Market().GetFuturesSymbols()
    if err != nil {
        t.Fatalf("Failed to get symbols: %v", err)
    }
    
    if symbols == nil {
        t.Error("Expected symbols, got nil")
    }
}

Integration Testing

func TestOrderCreation(t *testing.T) {
    if testing.Short() {
        t.Skip("Skipping integration test")
    }
    
    client := bingx.NewClient(
        os.Getenv("BINGX_API_KEY"),
        os.Getenv("BINGX_API_SECRET"),
    )
    
    // Test order creation
    order, err := client.Trade().CreateTestOrder(params)
    if err != nil {
        t.Fatalf("Test order failed: %v", err)
    }
}

Running Tests

# Run all tests
go test ./...

# Run with coverage
go test -cover ./...

# Run specific test
go test -run TestMarketData

# Skip integration tests
go test -short ./...

Performance

• Request Latency: < 50ms (network dependent)
• Memory Usage: ~2MB per client instance
• Concurrent Requests: Supports 1000+ concurrent goroutines
• Signature Generation: < 1ms per request

Optimization Tips

1. Connection Pooling: HTTP client reuses connections automatically
2. Batch Operations: Use batch methods for multiple orders
3. Caching: Cache market data locally when appropriate
4. Rate Limiting: Implement client-side rate limiting to avoid API limits

// Example: Rate-limited requests
import "golang.org/x/time/rate"

limiter := rate.NewLimiter(rate.Limit(10), 1) // 10 requests per second

func makeRequest() {
    limiter.Wait(context.Background())
    client.Market().GetLatestPrice("BTC-USDT")
}

Roadmap

Planned (v1.1.0)

• Order builder with fluent interface
• Rate limiter middleware
• Request/response logging
• Retry with exponential backoff

Future (v2.0.0)

• Built-in technical indicators
• Strategy backtesting framework
• Portfolio management tools
• Event-driven architecture

Creating API Keys

1. Login to your BingX account
2. Go to API Management
3. Create API key, configure permissions (Read, Trade)
4. Set IP whitelist (recommended)
5. Save your API Key and Secret Key — the secret is shown only once
