1. Getting Started - Market Data

import 'package:babel_binance/babel_binance.dart';

void main() async {
  final binance = Binance(); // No API key needed for public data

  // Get server time
  final serverTime = await binance.spot.market.getServerTime();

  // Get exchange information
  final exchangeInfo = await binance.spot.market.getExchangeInfo();
  print('Available trading pairs: ${exchangeInfo['symbols'].length}');

  // Get order book for BTC/USDT
  final orderBook = await binance.spot.market.getOrderBook('BTCUSDT', limit: 5);
  final bestBid = orderBook['bids'][0][0];
  final bestAsk = orderBook['asks'][0][0];
  print('BTC/USDT Best Bid: \$${bestBid}, Best Ask: \$${bestAsk}');
}

2. Risk-Free Trading - Three Options

Babel Binance offers three different ways to test your trading strategies safely:

🎮 Option 1: Simulated Trading (Built-in Simulation)

import 'package:babel_binance/babel_binance.dart';

void main() async {
  final binance = Binance();

  print('🎯 Testing Trading Strategies (Simulation Mode)');
  
  // Simulate buying Bitcoin with market order
  final buyOrder = await binance.spot.simulatedTrading.simulatePlaceOrder(
    symbol: 'BTCUSDT',
    side: 'BUY',
    type: 'MARKET',
    quantity: 0.001, // Buy 0.001 BTC
  );
  
  print('✅ Market Buy Order Executed');
  print('   Order ID: ${buyOrder['orderId']}');
  print('   Status: ${buyOrder['status']}');
  print('   Filled: ${buyOrder['executedQty']} BTC');
  print('   Cost: \$${buyOrder['cummulativeQuoteQty']}');
}

🧪 Option 2: Testnet Trading (Real API, Test Money)

import 'package:babel_binance/babel_binance.dart';

void main() async {
  // Get your testnet API keys from: https://testnet.binance.vision/
  final binance = Binance.testnet(
    apiKey: 'your_testnet_api_key',
    apiSecret: 'your_testnet_secret',
  );

  print('🧪 Testing on Binance Testnet');
  
  // Real API call to testnet with test money
  final ticker = await binance.testnetSpot.market.get24HrTicker('BTCUSDT');
  print('BTC Price on Testnet: \$${ticker['lastPrice']}');
  
  // Place real order on testnet (no real money)
  final order = await binance.testnetSpot.trading.placeOrder(
    symbol: 'BTCUSDT',
    side: 'BUY',
    type: 'MARKET',
    quantity: 0.001,
  );
  
  print('✅ Real Testnet Order Placed');
  print('   Order ID: ${order['orderId']}');
  print('   Status: ${order['status']}');
}

💰 Option 3: Live Trading (Real Money)

import 'package:babel_binance/babel_binance.dart';

void main() async {
  // ⚠️ LIVE TRADING - REAL MONEY AT RISK!
  final binance = Binance(
    apiKey: 'your_live_api_key',
    apiSecret: 'your_live_secret',
  );

  // Always start with small amounts!
  final order = await binance.spot.trading.placeOrder(
    symbol: 'BTCUSDT',
    side: 'BUY',
    type: 'MARKET',
    quantity: 0.0001, // Very small amount
  );
}

3. Currency Conversion Simulation

import 'package:babel_binance/babel_binance.dart';

void main() async {
  final binance = Binance();

  print('💱 Currency Conversion Simulation');
  
  // Step 1: Get conversion quote
  final quote = await binance.simulatedConvert.simulateGetQuote(
    fromAsset: 'ETH',
    toAsset: 'BTC',
    fromAmount: 1.0, // Convert 1 ETH to BTC
  );
  
  print('📋 Conversion Quote');
  print('   Quote ID: ${quote['quoteId']}');
  print('   Converting: 1.0 ETH → ${quote['toAmount']} BTC');
  print('   Exchange Rate: ${quote['ratio']}');
  print('   Valid for: ${quote['validTime']} seconds');
  
  // Step 2: Accept the quote
  final conversion = await binance.simulatedConvert.simulateAcceptQuote(
    quoteId: quote['quoteId'],
  );
  
  if (conversion['orderStatus'] == 'SUCCESS') {
    print('✅ Conversion Successful');
    print('   Conversion ID: ${conversion['orderId']}');
    
    // Step 3: Check conversion details
    final details = await binance.simulatedConvert.simulateOrderStatus(
      orderId: conversion['orderId'],
    );
    
    print('💰 Conversion Details');
    print('   From: ${details['fromAmount']} ${details['fromAsset']}');
    print('   To: ${details['toAmount']} ${details['toAsset']}');
    print('   Fee: ${details['fee']} ${details['feeAsset']}');
  } else {
    print('❌ Conversion Failed: ${conversion['errorMsg']}');
  }
}

4. WebSocket Real-Time Data

import 'package:babel_binance/babel_binance.dart';
import 'dart:async';

void main() async {
  final binance = Binance(apiKey: 'YOUR_API_KEY'); // Requires API key
  final websockets = Websockets();

  print('🔌 Connecting to Real-Time Data Stream');
  
  try {
    // Create user data stream
    final listenKeyData = await binance.spot.userDataStream.createListenKey();
    final listenKey = listenKeyData['listenKey'];
    
    print('✅ Listen key created: ${listenKey.substring(0, 10)}...');
    
    // Connect to WebSocket stream
    final stream = websockets.connectToStream(listenKey);
    late StreamSubscription subscription;
    
    subscription = stream.listen(
      (message) {
        print('📨 Real-time update: $message');
      },
      onError: (error) {
        print('❌ Stream error: $error');
      },
      onDone: () {
        print('🔌 Stream closed');
      },
    );
    
    // Keep alive for 30 seconds
    print('📡 Listening for 30 seconds...');
    await Future.delayed(Duration(seconds: 30));
    
    // Clean up
    await subscription.cancel();
    await binance.spot.userDataStream.closeListenKey(listenKey);
    print('🛑 Connection closed');
    
  } catch (e) {
    print('❌ Error: $e');
  }
}

5. Performance & Timing Analysis

import 'package:babel_binance/babel_binance.dart';

void main() async {
  final binance = Binance();

  print('⏱️ Performance Analysis');
  
  // Measure order processing time
  final orderStopwatch = Stopwatch()..start();
  await binance.spot.simulatedTrading.simulatePlaceOrder(
    symbol: 'BTCUSDT',
    side: 'BUY',
    type: 'MARKET',
    quantity: 0.001,
  );
  orderStopwatch.stop();
  
  // Measure quote processing time
  final quoteStopwatch = Stopwatch()..start();
  await binance.simulatedConvert.simulateGetQuote(
    fromAsset: 'BTC',
    toAsset: 'USDT',
    fromAmount: 0.001,
  );
  quoteStopwatch.stop();
  
  // Measure conversion time
  final convertStopwatch = Stopwatch()..start();
  await binance.simulatedConvert.simulateAcceptQuote(quoteId: 'test');
  convertStopwatch.stop();
  
  print('📊 Timing Results:');
  print('   Order Processing: ${orderStopwatch.elapsedMilliseconds}ms');
  print('   Quote Generation: ${quoteStopwatch.elapsedMilliseconds}ms');
  print('   Conversion Time: ${convertStopwatch.elapsedMilliseconds}ms');
  
  // Performance recommendations
  if (orderStopwatch.elapsedMilliseconds > 1000) {
    print('⚠️  Consider optimizing order processing');
  }
  if (quoteStopwatch.elapsedMilliseconds > 800) {
    print('⚠️  Quote generation is slower than expected');
  }
  
  print('✅ Performance analysis complete');
}

Simulation Features

Why Use Simulation?

The simulation features allow you to:

Test trading strategies without risking real money
Measure latency and timing for your applications
Develop and debug trading bots safely
Learn the API without API rate limits or authentication concerns

Realistic Timing

Our simulation includes realistic processing delays based on actual Binance performance:

Operation	Typical Delay	Range
Market Orders	~200ms	50-500ms
Limit Orders	~200ms	50-500ms
Order Status	~60ms	20-100ms
Convert Quote	~400ms	100-800ms
Convert Execute	~1.5s	500ms-3s
Convert Status	~125ms	50-200ms

Simulated Trading

final binance = Binance();

// Simulate a market buy order
final marketOrder = await binance.spot.simulatedTrading.simulatePlaceOrder(
  symbol: 'BTCUSDT',
  side: 'BUY',
  type: 'MARKET',
  quantity: 0.001,
);

// Simulate a limit sell order
final limitOrder = await binance.spot.simulatedTrading.simulatePlaceOrder(
  symbol: 'ETHUSDT',
  side: 'SELL',
  type: 'LIMIT',
  quantity: 0.1,
  price: 3200.0,
  timeInForce: 'GTC',
);

// Check order status
final status = await binance.spot.simulatedTrading.simulateOrderStatus(
  symbol: 'BTCUSDT',
  orderId: int.parse(marketOrder['orderId'].toString()),
);

Simulated Convert

// Get conversion quote
final quote = await binance.simulatedConvert.simulateGetQuote(
  fromAsset: 'BTC',
  toAsset: 'USDT',
  fromAmount: 0.001,
);

// Accept the quote
final conversion = await binance.simulatedConvert.simulateAcceptQuote(
  quoteId: quote['quoteId'],
);

// Check conversion status
final status = await binance.simulatedConvert.simulateOrderStatus(
  orderId: conversion['orderId'],
);

// Get conversion history
final history = await binance.simulatedConvert.simulateConversionHistory(
  limit: 10,
);

Timing Analysis

final stopwatch = Stopwatch()..start();

await binance.spot.simulatedTrading.simulatePlaceOrder(
  symbol: 'BTCUSDT',
  side: 'BUY',
  type: 'MARKET',
  quantity: 0.001,
);

stopwatch.stop();
print('Order took ${stopwatch.elapsedMilliseconds}ms');

🌐 Multiple API Endpoints & Failover

Babel Binance automatically provides multiple endpoint support with intelligent failover for enhanced reliability and uptime.

Supported Endpoint Types

API Type	Primary Endpoint	Failover Endpoints
Spot	`api.binance.com`	`api1.binance.com`, `api2.binance.com`, `api3.binance.com`, `api4.binance.com`
Futures USD-M	`fapi.binance.com`	`fapi1.binance.com`, `fapi2.binance.com`, `fapi3.binance.com`
Futures COIN-M	`dapi.binance.com`	`dapi1.binance.com`, `dapi2.binance.com`

How It Works

final binance = Binance();

// Automatically uses failover endpoints if primary fails
final ticker = await binance.spot.market.get24HrTicker('BTCUSDT');

// Check which endpoint is currently active
print('Active endpoint: ${binance.spot.market.currentEndpoint}');

// View all available endpoints
print('Available endpoints: ${binance.spot.market.availableEndpoints}');

Key Benefits

🚀 Automatic Failover: Seamlessly switches to backup servers on network issues
🌐 Multiple Geographic Regions: Access distributed Binance infrastructure
🔄 Smart Recovery: Automatically returns to primary endpoint when available
📊 Enhanced Uptime: Significantly improved reliability for production applications
🛡️ Zero Configuration: Works out-of-the-box with no additional setup required

The failover system automatically detects connection issues and rotates through available endpoints until a successful connection is established. Once service is restored, it intelligently returns to the primary endpoint for optimal performance.

WebSocket Usage

Typed Multi-Symbol Streams (Recommended)

Subscribe to real-time data for multiple symbols using a single WebSocket connection:

import 'package:babel_binance/babel_binance.dart';

void main() async {
  final binance = Binance(); // No API key needed for public streams

  // Real-time price updates for multiple symbols
  binance.priceStream(['BTCUSDT', 'ETHUSDT', 'SOLUSDT']).listen((event) {
    print('${event.symbol}: \$${event.close}');
    // Access typed fields: event.open, event.high, event.low, event.baseVolume
  });

  // Candlestick/Kline stream with closed candle detection
  binance.candleStream(['BTCUSDT'], '5m').listen((event) {
    if (event.isClosed) {
      print('Candle closed: O=${event.open} H=${event.high} L=${event.low} C=${event.close}');
    }
  });

  // Aggregate trade stream for tick-level data
  binance.tradeStream(['BTCUSDT']).listen((event) {
    print('${event.isBuy ? "BUY" : "SELL"} ${event.quantity} @ \$${event.price}');
  });

  // Best bid/ask prices
  binance.bookTickerStream(['BTCUSDT']).listen((event) {
    print('Spread: \$${event.spread.toStringAsFixed(2)}');
  });
}

Testnet with Production Prices

Trade on testnet but get real market prices:

final binance = Binance.testnet(
  apiKey: 'testnet-key',
  apiSecret: 'testnet-secret',
  useProductionPrices: true,  // Real market data!
);

Event Classes

All events support fromJson() and toJson():

Event Class	Stream Type	Key Fields
`MiniTickerEvent`	`priceStream()`	`symbol`, `close`, `open`, `high`, `low`, `baseVolume`
`KlineEvent`	`candleStream()`	`symbol`, `interval`, `open`, `high`, `low`, `close`, `isClosed`
`AggTradeEvent`	`tradeStream()`	`symbol`, `price`, `quantity`, `isBuy`, `tradeTime`
`BookTickerEvent`	`bookTickerStream()`	`symbol`, `bestBidPrice`, `bestAskPrice`, `spread`
`TickerEvent`	`tickerStream()`	`symbol`, `priceChangePercent`, `lastPrice`, `baseVolume`

User Data Stream (Legacy)

final binance = Binance(apiKey: 'YOUR_API_KEY');
final websockets = Websockets();

// Create listen key for user data stream
final listenKeyData = await binance.spot.userDataStream.createListenKey();
final listenKey = listenKeyData['listenKey'];

// Connect to user data stream
final stream = websockets.connectToStream(listenKey);
stream.listen((message) {
  print('Received: $message');
});

// Don't forget to close the listen key when done
await binance.spot.userDataStream.closeListenKey(listenKey);

Testing

To run the tests, including authenticated tests, set the BINANCE_API_KEY environment variable:

# Windows (PowerShell)
$env:BINANCE_API_KEY="your_api_key"
dart test

# Linux/macOS
export BINANCE_API_KEY="your_api_key"
dart test

Without the environment variable, authenticated tests will be skipped.

Order Status	80ms	150ms	Lightweight queries
WebSocket Connect	500ms	1200ms	Initial connection
Quote Generation	400ms	800ms	Convert operations

🚀 Production Tips

Error Handling

try {
  final order = await binance.spot.simulatedTrading.simulatePlaceOrder(
    symbol: 'BTCUSDT',
    side: 'BUY',
    type: 'MARKET',
    quantity: 0.001,
  );
  print('Order successful: ${order['orderId']}');
} catch (e) {
  print('Order failed: $e');
  // Implement retry logic or fallback strategy
}

Rate Limiting

// Implement rate limiting for production use
class RateLimiter {
  static const maxRequestsPerSecond = 10;
  static DateTime lastRequest = DateTime.now();
  
  static Future<void> throttle() async {
    final now = DateTime.now();
    final timeSinceLastRequest = now.difference(lastRequest).inMilliseconds;
    
    if (timeSinceLastRequest < (1000 / maxRequestsPerSecond)) {
      await Future.delayed(
        Duration(milliseconds: (1000 / maxRequestsPerSecond).round() - timeSinceLastRequest)
      );
    }
    
    lastRequest = DateTime.now();
  }
}
