|
||||
|
||||
```python
|
||||
# Before (direct API calls)
|
||||
from tradingagents.dataflows import get_YFin_data
|
||||
data = get_YFin_data("AAPL", "2024-01-01", "2024-01-15")
|
||||

|
||||
data = get_YFin_data_cached("AAPL", "2024-01-01", "2024-01-15")
|
||||
```
|
||||
|
||||
### Available Cached Functions
|
||||
|
||||
```python
|
||||
from tradingagents.dataflows import (
|
||||
get_YFin_data_cached, # OHLCV data with caching
|
||||
get_YFin_data_window_cached, # Window-based OHLCV data
|
||||
get_finnhub_news_cached, # Finnhub news with caching
|
||||
get_google_news_cached, # Google News with caching
|
||||
get_technical_indicators_cached, # Technical indicators
|
||||
get_cache_statistics, # Performance monitoring
|
||||
clear_cache_data # Cache management
|
||||
)
|
||||
```
|
||||
|
||||
### Monitor Cache Performance
|
||||
|
||||
```python
|
||||
# Check cache performance
|
||||
stats = get_cache_statistics()
|
||||
print(stats)
|
||||
|
||||
# Example output:
|
||||
# Cache Hit Ratio: 78.3%
|
||||
# API Calls Saved: 64
|
||||
# Cache Size: 15.67 MB
|
||||
```
|
||||
|
||||
### Manage Cache Data
|
||||
|
||||
```python
|
||||
# Clear cache for specific symbol
|
||||
clear_cache_data(symbol="AAPL")
|
||||
|
||||
# Clear data older than 30 days
|
||||
clear_cache_data(older_than_days=30)
|
||||
|
||||
# Clear old data for specific symbol
|
||||
clear_cache_data(symbol="AAPL", older_than_days=7)
|
||||
```
|
||||
|
||||
## 📈 Expected Performance Benefits
|
||||
|
||||
### Speed Improvements
|
||||
- **Cache Hits**: 10-100x faster than API calls
|
||||
- **Overlapping Queries**: Only fetches missing data gaps
|
||||
- **Local Storage**: No network latency for cached data
|
||||
|
||||
### Cost Savings
|
||||
- **API Usage Reduction**: 60-90% fewer API calls
|
||||
- **Rate Limit Friendly**: Avoids hitting API limits
|
||||
- **Bandwidth Savings**: Local data storage
|
||||
|
||||
### Example Performance
|
||||
```python
|
||||
# First call: ~2.5 seconds (API + cache)
|
||||
data1 = get_YFin_data_cached("AAPL", "2024-01-01", "2024-01-15")
|
||||
|
||||
# Second identical call: ~0.05 seconds (cache hit)
|
||||
data2 = get_YFin_data_cached("AAPL", "2024-01-01", "2024-01-15")
|
||||
|
||||
# 50x faster! 🚀
|
||||
```

|
||||
## 🔄 Migration Strategy
|
||||
|
||||
### Gradual Migration (Recommended)
|
||||
1. **Start with high-frequency queries**: Replace most-used API calls first
|
||||
2. **Monitor performance**: Use `get_cache_statistics()` to track improvements
|
||||
3. **Expand coverage**: Gradually replace other API calls
|
||||
4. **Optimize cache**: Clear old data periodically
|
||||
|
||||
### Immediate Full Migration
|
||||
Replace all compatible API calls with cached versions:
|
||||
|
||||
| Original Function | Cached Function |
|
||||
|------------------|----------------|
|
||||
| `get_YFin_data()` | `get_YFin_data_cached()` |
|
||||
| `get_YFin_data_window()` | `get_YFin_data_window_cached()` |
|
||||
| `get_finnhub_news()` | `get_finnhub_news_cached()` |
|
||||
| `get_google_news()` | `get_google_news_cached()` |
|
||||
|
||||
## 💡 Usage Tips
|
||||
|
||||
1. **First Run**: Initial calls will be slower (building cache)
|
||||
2. **Repeated Queries**: Subsequent calls will be dramatically faster
|
||||
3. **Overlapping Ranges**: System automatically optimizes overlapping date ranges
|
||||
4. **Monitoring**: Check `get_cache_statistics()` regularly for performance insights
|
||||
5. **Maintenance**: Periodically clear old cache data to manage disk space
|
||||
|
||||
## 🛠️ Advanced Features

# Check what's cached vs. what needs fetching
|
||||
gaps, cached_entries = cache.check_cache_coverage(
|
||||
"AAPL", DataType.OHLCV, start_date, end_date
|
||||
)
|
||||
```
|
||||
|
||||
### Custom Cache Directory

Cache files are stored in: `data_cache/time_series/`
|
||||
|
||||
## 📖 Usage Examples
|
||||
|
||||
### Basic OHLCV Data Caching
|
||||
|
||||
```python
|
||||
from tradingagents.dataflows import get_YFin_data_cached
|
||||
|
||||
# First call - fetches from API and caches
|
||||
data = get_YFin_data_cached("AAPL", "2024-01-01", "2024-01-15")
|
||||
|
||||
# Second call - uses cache (much faster!)
|
||||
data = get_YFin_data_cached("AAPL", "2024-01-01", "2024-01-15")
|
||||
|
||||
# Overlapping range - only fetches new dates
|
||||
data = get_YFin_data_cached("AAPL", "2024-01-10", "2024-01-25")
|
||||
```
|
||||
|
||||
### Window-Based Data Retrieval
|
||||
|
||||
```python
|
||||
from tradingagents.dataflows import get_YFin_data_window_cached
|
||||
|
||||
# Get 30 days of data before current date
|
||||
data = get_YFin_data_window_cached("TSLA", "2024-01-15", 30)
|
||||
```
|
||||
|
||||
### News Data Caching

print(stats)
|
||||
|
||||
# Output example:
|
||||
# ## Financial Data Cache Statistics
|
||||
#
|
||||
# **Cache Performance:**
|
||||
# - Total Entries: 42
|
||||
# - Cache Size: 15.67 MB
|
||||
# - Hit Ratio: 78.3%
|
||||
# - Cache Hits: 89
|
||||
# - Cache Misses: 25
|
||||
# - API Calls Saved: 64
|
||||
```
|
||||
|
||||
### Cache Management
|
||||
|
||||
```python
|
||||
from tradingagents.dataflows import clear_cache_data
|
||||
|
||||
# Clear cache for specific symbol
|
||||
clear_cache_data(symbol="AAPL")
|
||||
|
||||
# Clear data older than 30 days
|
||||
clear_cache_data(older_than_days=30)
|
||||
|
||||
# Clear old data for specific symbol
|
||||
clear_cache_data(symbol="AAPL", older_than_days=7)
|
||||
```
|
||||
|
||||
## 🏗️ Architecture
|
||||
|
||||
### Core Components

## 📈 Performance Benefits
|
||||
|
||||
### Speed Improvements
|
||||
- **Cache Hits**: 10-100x faster than API calls
|
||||
- **Gap Filling**: Only fetches missing data
|
||||
- **Batch Operations**: Efficient for overlapping queries
|
||||
|
||||
### Cost Savings
|
||||
- **Reduced API Calls**: Can reduce API usage by 60-90%
|
||||
- **Rate Limit Friendly**: Avoids redundant API requests
|
||||
- **Bandwidth Efficient**: Local storage reduces network usage
|
||||
|
||||
### Example Performance
|
||||
|
||||
```python
|
||||
# First call: ~2.5 seconds (API fetch + cache)
|
||||
data1 = get_YFin_data_cached("AAPL", "2024-01-01", "2024-01-15")
|
||||
|
||||
# Second call: ~0.05 seconds (cache hit)
|
||||
data2 = get_YFin_data_cached("AAPL", "2024-01-01", "2024-01-15")
|
||||
|
||||
# 50x speed improvement!
|
||||
```
|
||||
|
||||
## 🔄 Migration Guide
|
||||
|
||||
### Replace Existing Functions
|
||||
|
||||
| Old Function | New Cached Function |
|
||||
|--------------|-------------------|
|
||||
| `get_YFin_data()` | `get_YFin_data_cached()` |
|
||||
| `get_YFin_data_window()` | `get_YFin_data_window_cached()` |
|
||||
| `get_finnhub_news()` | `get_finnhub_news_cached()` |
|
||||
| `get_google_news()` | `get_google_news_cached()` |
|
||||
|
||||
### Example Migration
|
||||
|
||||
```python
|
||||
# Before
|
||||
from tradingagents.dataflows import get_YFin_data
|
||||
data = get_YFin_data("AAPL", "2024-01-01", "2024-01-15")
|
||||
|
||||
# After
|
||||
from tradingagents.dataflows import get_YFin_data_cached
|
||||
data = get_YFin_data_cached("AAPL", "2024-01-01", "2024-01-15")
|
||||
|
||||
# Same interface, better performance!
|
||||
```
|
||||
|
||||
## 🛠️ Advanced Configuration
|
||||
|
||||
### Custom Cache Directory
|
||||
|
||||
```python
|
||||
from tradingagents.dataflows.time_series_cache import TimeSeriesCache
|
||||
|
||||
# Create cache with custom directory
|
||||
cache = TimeSeriesCache(cache_dir="/path/to/custom/cache")
|
||||
```
|
||||
|
||||
### Direct Cache API
|
||||
|
||||
```python
|
||||
from tradingagents.dataflows.time_series_cache import get_cache, DataType
|
||||
from datetime import datetime
|
||||
|
||||
cache = get_cache()
|
||||
|
||||
# Check cache coverage
|
||||
gaps, cached = cache.check_cache_coverage(
|
||||
"AAPL",
|
||||
DataType.OHLCV,
|
||||
datetime(2024, 1, 1),
|
||||
datetime(2024, 1, 15)
|
||||
)
|
||||
|
||||
# Fetch with custom function
|
||||
def my_fetch_function(symbol, start_date, end_date):
|
||||
# Your custom API fetch logic
|
||||
return pd.DataFrame(...)
|
||||
|
||||
data = cache.fetch_with_cache(
|
||||
"AAPL",
|
||||
DataType.OHLCV,
|
||||
datetime(2024, 1, 1),
|
||||
datetime(2024, 1, 15),
|
||||
my_fetch_function
|
||||
)
|
||||
```
|
||||
|
||||
## 🧪 Testing
|
||||
|
||||
Run the demo script to test the caching system:
|
||||
|
||||
```bash
|
||||
python demo_time_series_cache.py
|
||||
```
|
||||
|
||||
This will demonstrate:
|
||||
- OHLCV data caching performance
|
||||
- News data caching
|
||||
- Technical indicators caching
|
||||
- Cache statistics and management
|
||||
|
||||
## 🔍 Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
**Cache directory permissions**
|
||||
```bash
|
||||
# Ensure write permissions
|
||||
chmod 755 data_cache/time_series/
|
||||
```
|
||||
|
||||
**SQLite database locked**
|
||||
- Restart Python process
|
||||
- Check for concurrent access
|
||||
|
||||
**Missing data dependencies**
|
||||
```bash
|
||||
# Install required packages
|
||||
pip install pandas pyarrow sqlite3
|
||||
```
|
||||
|
||||
### Debug Mode
|
||||
|
||||
```python
|
||||
import logging
|
||||
logging.basicConfig(level=logging.INFO)
|
||||
|
||||
# Cache operations will now show detailed logs
|
||||
data = get_YFin_data_cached("AAPL", "2024-01-01", "2024-01-15")
|
||||
```
|
||||
|
||||
## 📋 Cache Statistics Explained
|
||||
|
||||
| Metric | Description |
|
||||
|--------|-------------|
|
||||
| **Total Entries** | Number of cached data segments |
|
||||
| **Cache Size** | Total disk space used (MB) |
|
||||
| **Hit Ratio** | % of requests served from cache |
|
||||
| **Cache Hits** | Number of successful cache retrievals |
|
||||
| **Cache Misses** | Number of API calls required |
|
||||
| **API Calls Saved** | Estimated API calls avoided |
|
||||
|
||||
## 🤝 Contributing
|
||||
|
||||
The cache system is designed to be extensible. To add new data types:
|
||||
|
||||
1. Add new `DataType` enum value
|
||||
2. Create wrapper function in `cached_api_wrappers.py`
|
||||
3. Add interface function in `interface.py`
|
||||
4. Update exports in `__init__.py`
