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

What's New in v3

🎯 Key Highlights

BingX API v3 brings powerful new features for institutional-grade trading:

1. TWAP Orders (Time-Weighted Average Price)

Execute large orders with minimal market impact by splitting them into smaller chunks over time.

// Execute 10 BTC over 1 hour in 1-minute intervals
client.Trade().PlaceTWAPOrder(map[string]interface{}{
    "symbol":   "BTC-USDT",
    "quantity": 10.0,
    "duration": 3600,
    "interval": 60,
})

2. Multi-Assets Margin Mode

Optimize margin usage across multiple positions with portfolio margin.

// Enable multi-assets mode
client.Trade().SwitchMultiAssetsMode(true, nil)

// Query margin rules and usage
rules, _ := client.Trade().GetMultiAssetsRules(nil)
margin, _ := client.Trade().GetMultiAssetsMargin(nil)

3. One-Click Position Reversal

Instantly reverse your position from LONG to SHORT or vice versa.

// Reverse position with one call
client.Trade().OneClickReversePosition("BTC-USDT", nil)
// Before: LONG 1.0 BTC → After: SHORT 1.0 BTC

4. Advanced Order Types

TRIGGER_LIMIT - Trigger orders with limit execution
TRAILING_STOP_MARKET - Dynamic stop-loss that follows price
TRAILING_TP_SL - Trailing take-profit and stop-loss

import "github.com/tigusigalpa/bingx-go/v2/services"

client.Trade().CreateOrder(map[string]interface{}{
    "type":             services.OrderTypeTrailingStopMarket,
    "activationPrice":  50000.0,
    "callbackRate":     1.0, // 1% trailing
})

5. Enhanced Risk Management

Position Risk Metrics:

risk, _ := client.Account().GetPositionRisk(&symbol, nil)
// Returns: liquidation price, leverage, margin ratio, unrealized PnL

Income/PnL Tracking:

incomeType := "REALIZED_PNL"
income, _ := client.Account().GetIncomeHistory(&symbol, &incomeType, nil, nil, 100, nil)

Commission Analysis:

commissions, _ := client.Account().GetCommissionHistory("BTC-USDT", nil, nil, 100, nil)

6. Enhanced Market Data

Open Interest & History
Funding Rate Information
Book Ticker (Best Bid/Ask)
Index Price
Mark Price

// Real-time open interest
oi, _ := client.Market().GetOpenInterest("BTC-USDT")

// Historical open interest
oiHistory, _ := client.Market().GetOpenInterestHistory("BTC-USDT", "5m", 100, nil, nil)

// Best bid/ask prices
bookTicker, _ := client.Market().GetBookTicker(&symbol)

    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()

Error Tests:

errors/errors_test.go - Custom exception handling

Example Tests

Testing Client Initialization

func TestNewClient(t *testing.T) {
    client := bingx.NewClient("test-key", "test-secret")
    
    if client == nil {
        t.Fatal("Expected client to be created")
    }
    
    if client.GetAPIKey() != "test-key" {
        t.Error("API key mismatch")
    }
}

Testing Commission Calculations

func TestCommissionCalculation(t *testing.T) {
    client := bingx.NewClient("", "")
    
    result := client.Trade().CalculateFuturesCommission(100.0, 10, nil)
    
    if result.PositionValue != 1000.0 {
        t.Errorf("Expected position value 1000.0, got %f", result.PositionValue)
    }
    
    if result.Commission != 0.45 {
        t.Errorf("Expected commission 0.45, got %f", result.Commission)
    }
}

Testing Parameter Validation

func TestSetLeverageValidation(t *testing.T) {
    client := bingx.NewClient("key", "secret")
    
    // Test invalid leverage (too high)
    _, err := client.Trade().SetLeverage("BTC-USDT", 126, nil, nil)
    if err == nil {
        t.Error("Expected error for leverage > 125")
    }
    
    // Test valid leverage
    _, err = client.Trade().SetLeverage("BTC-USDT", 50, nil, nil)
    // Will skip if no mock server, but validates parameters
}

Integration Testing

Most tests are designed as unit tests that validate:

Correct initialization
Parameter validation
Expected behavior of utility functions
Error handling for invalid inputs

Integration tests that require actual API calls are marked to skip:

func TestGetBalance(t *testing.T) {
    client := http.NewBaseHTTPClient("key", "secret", "https://api.test.com", "", "base64")
    service := NewAccountService(client)
    
    _, err := service.GetBalance()
    if err == nil {
        t.Skip("Skipping test - would require mock HTTP server")
    }
}

Continuous Integration

The library includes a GitHub Actions workflow (.github/workflows/test.yml) that:

Runs tests on every push and pull request
Tests against multiple Go versions (1.21, 1.22)
Generates coverage reports
Runs linting checks
Uploads coverage to Codecov

Test Documentation

For detailed testing information, see:

TESTING.md - Comprehensive testing guide with examples
TEST_SUMMARY.md - Complete test coverage overview
testdata/README.md - Test fixtures and mock data guide

Writing Tests

When contributing, follow these patterns:

// Table-driven tests for multiple scenarios
func TestBuildQuery(t *testing.T) {
    tests := []struct {
        name     string
        params   map[string]interface{}
        expected string
    }{
        {"Empty params", map[string]interface{}{}, ""},
        {"String param", map[string]interface{}{"symbol": "BTC-USDT"}, "symbol=BTC-USDT"},
        {"Multiple params", map[string]interface{}{"symbol": "BTC-USDT", "limit": 100}, "limit=100&symbol=BTC-USDT"},
    }
    
    for _, tt := range tests {
        t.Run(tt.name, func(t *testing.T) {
            result := buildQuery(tt.params)
            if result != tt.expected {
                t.Errorf("Expected %s, got %s", tt.expected, result)
            }
        })
    }
}

Test Utilities

The test suite includes:

Makefile - Quick test commands
test.sh - Bash script with options for verbose output and coverage
GitHub Actions workflow - Automated CI/CD testing
testdata/ - Directory for test fixtures and mock data

Coverage Goals

Current test coverage focuses on:

All public APIs and methods
Parameter validation
Error handling paths
Edge cases and boundary conditions
Commission calculations
Signature generation

Future enhancements will include:

Mock HTTP server for integration tests
WebSocket mock server
Performance benchmarks
Concurrent request testing

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

Connection Pooling: HTTP client reuses connections automatically
Batch Operations: Use batch methods for multiple orders
Caching: Cache market data locally when appropriate
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
