# Data Provider Quick Reference Guide
## Overview
Quick reference for using the multi-layered data provider system in the multi-modal trading system.
## Architecture Layers
```
COBY System → Core DataProvider → StandardizedDataProvider → Models
```
## Getting Started
### Basic Usage
```python
from core.standardized_data_provider import StandardizedDataProvider
# Initialize provider
provider = StandardizedDataProvider(
symbols=['ETH/USDT', 'BTC/USDT'],
timeframes=['1s', '1m', '1h', '1d']
)
# Start real-time processing
provider.start_real_time_processing()
# Get standardized input for models
base_input = provider.get_base_data_input('ETH/USDT')
# Validate data quality
if base_input and base_input.validate():
# Use data for model inference
pass
```
## BaseDataInput Structure
```python
@dataclass
class BaseDataInput:
symbol: str # 'ETH/USDT'
timestamp: datetime # Current time
# OHLCV Data (300 frames each)
ohlcv_1s: List[OHLCVBar] # 1-second bars
ohlcv_1m: List[OHLCVBar] # 1-minute bars
ohlcv_1h: List[OHLCVBar] # 1-hour bars
ohlcv_1d: List[OHLCVBar] # 1-day bars
btc_ohlcv_1s: List[OHLCVBar] # BTC reference
# COB Data
cob_data: Optional[COBData] # Order book data
# Technical Analysis
technical_indicators: Dict[str, float] # RSI, MACD, etc.
pivot_points: List[PivotPoint] # Williams pivots
# Cross-Model Feeding
last_predictions: Dict[str, ModelOutput] # Other model outputs
# Market Microstructure
market_microstructure: Dict[str, Any] # Order flow, etc.
```
## Common Operations
### Get Current Price
```python
# Multiple fallback methods
price = provider.get_current_price('ETH/USDT')
# Direct API call with cache
price = provider.get_live_price_from_api('ETH/USDT')
```
### Get Historical Data
```python
# Get OHLCV data
df = provider.get_historical_data(
symbol='ETH/USDT',
timeframe='1h',
limit=300
)
```
### Get COB Data
```python
# Get latest COB snapshot
cob_data = provider.get_latest_cob_data('ETH/USDT')
# Get COB imbalance metrics
imbalance = provider.get_current_cob_imbalance('ETH/USDT')
```
### Get Pivot Points
```python
# Get Williams Market Structure pivots
pivots = provider.calculate_williams_pivot_points('ETH/USDT')
```
### Store Model Output
```python
from core.data_models import ModelOutput
# Create model output
output = ModelOutput(
model_type='cnn',
model_name='williams_cnn_v2',
symbol='ETH/USDT',
timestamp=datetime.now(),
confidence=0.85,
predictions={
'action': 'BUY',
'action_confidence': 0.85,
'direction_vector': 0.7
},
hidden_states={'conv_features': tensor(...)},
metadata={'version': '2.1'}
)
# Store for cross-model feeding
provider.store_model_output(output)
```
### Get Model Outputs
```python
# Get all model outputs for a symbol
outputs = provider.get_model_outputs('ETH/USDT')
# Access specific model output
cnn_output = outputs.get('williams_cnn_v2')
```
## Data Validation
### Validate BaseDataInput
```python
base_input = provider.get_base_data_input('ETH/USDT')
if base_input:
# Check validation
is_valid = base_input.validate()
# Check data completeness
if len(base_input.ohlcv_1s) >= 100:
# Sufficient data for inference
pass
```
### Check Data Quality
```python
# Get data completeness metrics
if base_input:
ohlcv_complete = all([
len(base_input.ohlcv_1s) >= 100,
len(base_input.ohlcv_1m) >= 100,
len(base_input.ohlcv_1h) >= 100,
len(base_input.ohlcv_1d) >= 100
])
cob_complete = base_input.cob_data is not None
# Overall quality score (implement in Task 2.3)
# quality_score = base_input.data_quality_score()
```
## COB Data Access
### COB Data Structure
```python
@dataclass
class COBData:
symbol: str
timestamp: datetime
current_price: float
bucket_size: float # $1 ETH, $10 BTC
# Price Buckets (±20 around current price)
price_buckets: Dict[float, Dict[str, float]] # {price: {bid_vol, ask_vol}}
bid_ask_imbalance: Dict[float, float] # {price: imbalance}
# Moving Averages (±5 buckets)
ma_1s_imbalance: Dict[float, float]
ma_5s_imbalance: Dict[float, float]
ma_15s_imbalance: Dict[float, float]
ma_60s_imbalance: Dict[float, float]
# Order Flow
order_flow_metrics: Dict[str, float]
```
### Access COB Buckets
```python
if base_input.cob_data:
cob = base_input.cob_data
# Get current price
current_price = cob.current_price
# Get bid/ask volumes for specific price
price_level = current_price + cob.bucket_size # One bucket up
if price_level in cob.price_buckets:
bucket = cob.price_buckets[price_level]
bid_volume = bucket.get('bid_volume', 0)
ask_volume = bucket.get('ask_volume', 0)
# Get imbalance for price level
imbalance = cob.bid_ask_imbalance.get(price_level, 0)
# Get moving averages
ma_1s = cob.ma_1s_imbalance.get(price_level, 0)
ma_5s = cob.ma_5s_imbalance.get(price_level, 0)
```
## Subscriber Pattern
### Subscribe to Data Updates
```python
def my_data_callback(tick):
"""Handle real-time tick data"""
print(f"Received tick: {tick.symbol} @ {tick.price}")
# Subscribe to data updates
subscriber_id = provider.subscribe_to_data(
callback=my_data_callback,
symbols=['ETH/USDT'],
subscriber_name='my_model'
)
# Unsubscribe when done
provider.unsubscribe_from_data(subscriber_id)
```
## Configuration
### Key Configuration Options
```yaml
# config.yaml
data_provider:
symbols:
- ETH/USDT
- BTC/USDT
timeframes:
- 1s
- 1m
- 1h
- 1d
cache:
enabled: true
candles_per_timeframe: 1500
cob:
enabled: true
bucket_sizes:
ETH/USDT: 1.0 # $1 buckets
BTC/USDT: 10.0 # $10 buckets
price_ranges:
ETH/USDT: 5.0 # ±$5 for imbalance
BTC/USDT: 50.0 # ±$50 for imbalance
websocket:
update_speed: 100ms
max_depth: 1000
reconnect_delay: 1.0
max_reconnect_delay: 60.0
```
## Performance Tips
### Optimize Data Access
```python
# Cache BaseDataInput for multiple models
base_input = provider.get_base_data_input('ETH/USDT')
# Use cached data for all models
cnn_input = base_input # CNN uses full data
rl_input = base_input # RL uses full data + CNN outputs
# Avoid repeated calls
# BAD: base_input = provider.get_base_data_input('ETH/USDT') # Called multiple times
# GOOD: Cache and reuse
```
### Monitor Performance
```python
# Check subscriber statistics
stats = provider.distribution_stats
print(f"Total ticks received: {stats['total_ticks_received']}")
print(f"Total ticks distributed: {stats['total_ticks_distributed']}")
print(f"Distribution errors: {stats['distribution_errors']}")
```
## Troubleshooting
### Common Issues
#### 1. No Data Available
```python
base_input = provider.get_base_data_input('ETH/USDT')
if base_input is None:
# Check if data provider is started
if not provider.data_maintenance_active:
provider.start_automatic_data_maintenance()
# Check if COB collection is started
if not provider.cob_collection_active:
provider.start_cob_collection()
```
#### 2. Incomplete Data
```python
if base_input:
# Check frame counts
print(f"1s frames: {len(base_input.ohlcv_1s)}")
print(f"1m frames: {len(base_input.ohlcv_1m)}")
print(f"1h frames: {len(base_input.ohlcv_1h)}")
print(f"1d frames: {len(base_input.ohlcv_1d)}")
# Wait for data to accumulate
if len(base_input.ohlcv_1s) < 100:
print("Waiting for more data...")
time.sleep(60) # Wait 1 minute
```
#### 3. COB Data Missing
```python
if base_input and base_input.cob_data is None:
# Check COB collection status
if not provider.cob_collection_active:
provider.start_cob_collection()
# Check WebSocket status
if hasattr(provider, 'enhanced_cob_websocket'):
ws = provider.enhanced_cob_websocket
status = ws.status.get('ETH/USDT')
print(f"WebSocket connected: {status.connected}")
print(f"Last message: {status.last_message_time}")
```
#### 4. Price Data Stale
```python
# Force refresh price
price = provider.get_live_price_from_api('ETH/USDT')
# Check cache freshness
if 'ETH/USDT' in provider.live_price_cache:
cached_price, timestamp = provider.live_price_cache['ETH/USDT']
age = datetime.now() - timestamp
print(f"Price cache age: {age.total_seconds()}s")
```
## Best Practices
### 1. Always Validate Data
```python
base_input = provider.get_base_data_input('ETH/USDT')
if base_input and base_input.validate():
# Safe to use for inference
model_output = model.predict(base_input)
else:
# Log and skip inference
logger.warning("Invalid or incomplete data, skipping inference")
```
### 2. Handle Missing Data Gracefully
```python
# Never use synthetic data
if base_input is None:
logger.error("No data available")
return None # Don't proceed with inference
# Check specific components
if base_input.cob_data is None:
logger.warning("COB data unavailable, using OHLCV only")
# Proceed with reduced features or skip
```
### 3. Store Model Outputs
```python
# Always store outputs for cross-model feeding
output = model.predict(base_input)
provider.store_model_output(output)
# Other models can now access this output
```
### 4. Monitor Data Quality
```python
# Implement quality checks
def check_data_quality(base_input):
if not base_input:
return 0.0
score = 0.0
# OHLCV completeness (40%)
ohlcv_score = min(1.0, len(base_input.ohlcv_1s) / 300) * 0.4
score += ohlcv_score
# COB availability (30%)
cob_score = 0.3 if base_input.cob_data else 0.0
score += cob_score
# Pivot points (20%)
pivot_score = 0.2 if base_input.pivot_points else 0.0
score += pivot_score
# Freshness (10%)
age = (datetime.now() - base_input.timestamp).total_seconds()
freshness_score = max(0, 1.0 - age / 60) * 0.1 # Decay over 1 minute
score += freshness_score
return score
# Use quality score
quality = check_data_quality(base_input)
if quality < 0.8:
logger.warning(f"Low data quality: {quality:.2f}")
```
