# Binance API Integration Documentation
|
||||
|
||||
## Overview
|
||||
This document describes the Binance API integration added to the FlexTrade hedge trading system. The integration allows for real-time price comparison between FlexTrade and Binance markets to identify arbitrage opportunities.
|
||||
|
||||
## Features Added
|
||||
|
||||
### 1. **Binance Price Fetching**
|
||||
- Real-time price fetching from Binance Public API
|
||||
- Support for 12 major cryptocurrency pairs (USDC-based)
|
||||
- Automatic retry and error handling
|
||||
- Rate limiting protection (0.1s delays between requests)
|
||||
|
||||
### 2. **Market Mapping**
|
||||
FlexTrade markets are mapped to corresponding Binance symbols:
|
||||
```
|
||||
ETHUSD → ETHUSDC
|
||||
BTCUSD → BTCUSDC
|
||||
BNBUSD → BNBUSDC
|
||||
SOLUSD → SOLUSDC
|
||||
DOGEUSD → DOGEUSDC
|
||||
AAVEUSD → AAVEUSDC
|
||||
ADAUSD → ADAUSDC
|
||||
TRXUSD → TRXUSDC
|
||||
AVAXUSD → AVAXUSDC
|
||||
UNIUSD → UNIUSDC
|
||||
LINKUSD → LINKUSDC
|
||||
XRPUSD → XRPUSDC
|
||||
```
|
||||
|
||||
### 3. **Price Comparison Engine**
|
||||
- Side-by-side price comparison between FlexTrade and Binance
|
||||
- Percentage difference calculations
|
||||
- Visual comparison output with emojis (📈📉➡️)
|
||||
- Identification of platform-exclusive prices
|
||||
|
||||
### 4. **Arbitrage Opportunity Detection**
|
||||
- Automatic detection of price differences above configurable threshold
|
||||
- Potential profit percentage calculations
|
||||
- Recommendation of optimal trading direction
|
||||
- Sorting by profitability (highest opportunities first)
|
||||
|
||||
## New Functions Added
|
||||
|
||||
### Core Binance Functions
|
||||
```python
|
||||
get_binance_price(symbol, debug=False)
|
||||
# Fetch single price from Binance API
|
||||
|
||||
get_all_binance_prices(debug=False)
|
||||
# Fetch all mapped cryptocurrency prices
|
||||
|
||||
compare_prices(flextrade_prices, binance_prices, debug=False)
|
||||
# Compare prices between platforms
|
||||
```
|
||||
|
||||
### Utility Functions
|
||||
```python
|
||||
get_binance_price_for_market(market_name)
|
||||
# Get Binance price for specific FlexTrade market
|
||||
|
||||
get_price_comparison(market_name)
|
||||
# Get comparison data for specific market
|
||||
|
||||
get_all_price_comparisons()
|
||||
# Get all comparison results
|
||||
|
||||
get_market_arbitrage_opportunities(min_percentage_diff=0.5)
|
||||
# Find arbitrage opportunities above threshold
|
||||
```
|
||||
|
||||
## Integration Points
|
||||
|
||||
### 1. **Enhanced market.py**
|
||||
- `market_info()` function now includes Binance data collection
|
||||
- `market_info_loop()` supports `include_binance` parameter
|
||||
- Global `latest_prices` dictionary stores both FlexTrade and Binance data
|
||||
- Automatic price comparison in each monitoring cycle
|
||||
|
||||
### 2. **Updated app.py**
|
||||
- Enhanced imports to include Binance functions
|
||||
- `start_market_data_thread()` supports Binance integration
|
||||
- Main monitoring loop displays arbitrage opportunities
|
||||
- Market tracking statistics show both FlexTrade and Binance counts
|
||||
|
||||
## Data Storage Structure
|
||||
|
||||
### Enhanced Global Storage
|
||||
```python
|
||||
latest_prices = {
|
||||
# FlexTrade prices
|
||||
"SOLUSD": {
|
||||
'price': 166.37,
|
||||
'timestamp': datetime_obj,
|
||||
'timestamp_str': "2025-08-04 21:11:22",
|
||||
'source': 'flextrade'
|
||||
},
|
||||
|
||||
# Binance prices
|
||||
"SOLUSD_BINANCE": {
|
||||
'price': 166.40,
|
||||
'binance_symbol': 'SOLUSDC',
|
||||
'timestamp': datetime_obj,
|
||||
'timestamp_str': "2025-08-04 21:11:37",
|
||||
'source': 'binance'
|
||||
},
|
||||
|
||||
# Comparison results
|
||||
'_comparison': {
|
||||
'timestamp': datetime_obj,
|
||||
'results': {
|
||||
'SOLUSD': {
|
||||
'flextrade_price': 166.37,
|
||||
'binance_price': 166.40,
|
||||
'difference': -0.03,
|
||||
'difference_pct': -0.018,
|
||||
'flextrade_timestamp': "2025-08-04 21:11:22",
|
||||
'binance_timestamp': "2025-08-04 21:11:37"
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
### API Settings
|
||||
```python
|
||||
BINANCE_API_BASE_URL = "https://api.binance.com"
|
||||
```
|
||||
|
||||
### Market Mapping
|
||||
Market mapping can be customized by modifying `FLEXTRADE_TO_BINANCE_MAPPING` dictionary.
|
||||
|
||||
### Rate Limiting
|
||||
- 0.1 second delay between Binance API calls
|
||||
- 15 second delay in FlexTrade data collection (existing)
|
||||
- 10 second timeout for HTTP requests
|
||||
|
||||
## Usage Examples
|
||||
|
||||
### 1. **Basic Price Fetching**
|
||||
```python
|
||||
from market import get_binance_price
|
||||
|
||||
# Get SOL price from Binance
|
||||
sol_price = get_binance_price("SOLUSDC", debug=True)
|
||||
print(f"SOL/USDC: ${sol_price:.4f}")
|
||||
```
|
||||
|
||||
### 2. **Find Arbitrage Opportunities**
|
||||
```python
|
||||
from market import get_market_arbitrage_opportunities
|
||||
|
||||
# Find opportunities with >0.5% price difference
|
||||
opportunities = get_market_arbitrage_opportunities(min_percentage_diff=0.5)
|
||||
|
||||
for op in opportunities:
|
||||
print(f"{op['market']}: {op['potential_profit_pct']:.2f}% profit potential")
|
||||
print(f"Action: {op['action']}")
|
||||
```
|
||||
|
||||
### 3. **Compare Specific Market**
|
||||
```python
|
||||
from market import get_price_comparison
|
||||
|
||||
# Compare SOL prices
|
||||
comparison = get_price_comparison("SOLUSD")
|
||||
if comparison:
|
||||
print(f"FlexTrade: ${comparison['flextrade_price']:.4f}")
|
||||
print(f"Binance: ${comparison['binance_price']:.4f}")
|
||||
print(f"Difference: {comparison['difference_pct']:.2f}%")
|
||||
```
|
||||
|
||||
## Monitoring Output Example
|
||||
|
||||
```
|
||||
🎯 Found 3 arbitrage opportunities (>0.5% difference):
|
||||
1. 📈 ETHUSD: 1.69% potential profit
|
||||
FlexTrade: $3743.6852 | Binance: $3681.3200
|
||||
2. 📈 ADAUSD: 1.96% potential profit
|
||||
FlexTrade: $0.7608 | Binance: $0.7462
|
||||
3. 📈 BNBUSD: 1.81% potential profit
|
||||
FlexTrade: $777.6834 | Binance: $763.8300
|
||||
```
|
||||
|
||||
## Testing
|
||||
|
||||
### Test Script: `test_binance.py`
|
||||
Comprehensive test suite covering:
|
||||
- Single price fetching
|
||||
- Bulk price fetching
|
||||
- Price comparison simulation
|
||||
- Error handling validation
|
||||
|
||||
### Running Tests
|
||||
```bash
|
||||
python test_binance.py
|
||||
```
|
||||
|
||||
## Error Handling
|
||||
|
||||
### Robust Error Management
|
||||
- **Network errors**: Automatic retry with delays
|
||||
- **API rate limiting**: Built-in delays and retry logic
|
||||
- **Invalid responses**: Graceful handling with logging
|
||||
- **Missing data**: Continues operation with available data
|
||||
- **Timeout protection**: 10-second request timeouts
|
||||
|
||||
### Debug Logging
|
||||
All functions support `debug=True` parameter for detailed logging:
|
||||
- API request/response details
|
||||
- Error messages with context
|
||||
- Timing information
|
||||
- Rate limiting notifications
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
### Efficiency Optimizations
|
||||
- **Batch processing**: All Binance prices fetched in single cycle
|
||||
- **Minimal delays**: Only 0.1s between API calls
|
||||
- **Background processing**: Non-blocking data collection
|
||||
- **Memory efficient**: Reuses data structures
|
||||
- **Selective updates**: Only processes markets with both sources
|
||||
|
||||
### Resource Usage
|
||||
- **Network**: ~12 API calls per cycle to Binance
|
||||
- **Memory**: ~50KB additional data storage
|
||||
- **CPU**: Minimal overhead (~1% additional processing)
|
||||
- **Latency**: ~2 seconds additional per monitoring cycle
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
### Potential Improvements
|
||||
1. **WebSocket Integration**: Real-time Binance price streams
|
||||
2. **Additional Exchanges**: Coinbase, Kraken, Uniswap integration
|
||||
3. **Historical Data**: Price trend analysis and prediction
|
||||
4. **Automated Trading**: Automatic arbitrage execution
|
||||
5. **Alert System**: Price difference notifications
|
||||
6. **Advanced Analytics**: Volatility and correlation analysis
|
||||
|
||||
