🚀 Quick Start

Generate Synthetic OHLCV Data

from src.augmentation.synthetic_generator import CryptoSyntheticGenerator, SyntheticDataConfig
from src.gan.timegan import create_crypto_timegan
import pandas as pd

# Configure generator
config = SyntheticDataConfig(
    method='statistical',  # or 'timegan', 'gan', 'vae'
    n_samples=1000,
    seq_len=24,
    preserve_statistics=True
)

# Create generator
generator = CryptoSyntheticGenerator(config)

# Generate synthetic BTC data
synthetic_btc = generator.generate_ohlcv(
    symbol="BTCUSDT",
    interval="1h"
)

print(synthetic_btc.head())
# Output:
#         open      high       low     close    volume
# 0  50234.12  50456.78  49987.34  50123.45   1234.56
# 1  50123.45  50234.67  50012.23  50178.90   1345.67
# ...

Train TimeGAN on Real Data

from src.gan.timegan import create_crypto_timegan
import numpy as np

# Load your data
real_data = pd.read_csv('btc_ohlcv.csv')
data_array = real_data[['open', 'high', 'low', 'close', 'volume']].values

# Normalize data
from sklearn.preprocessing import MinMaxScaler
scaler = MinMaxScaler()
normalized_data = scaler.fit_transform(data_array)

# Reshape for TimeGAN [samples, sequence_length, features]
seq_len = 24
n_samples = len(normalized_data) // seq_len
data_reshaped = normalized_data[:n_samples * seq_len].reshape(n_samples, seq_len, 5)

# Create and train TimeGAN
timegan = create_crypto_timegan(
    seq_len=24,
    n_features=5,
    hidden_dim=128
)

# Train model
timegan.fit(
    data_reshaped,
    embedding_epochs=500,
    supervisor_epochs=500,
    joint_epochs=500
)

# Generate synthetic data
synthetic = timegan.generate(n_samples=100)
synthetic_scaled = scaler.inverse_transform(synthetic.reshape(-1, 5))

Add Market Events

# Add crash events
data_with_crashes = generator.add_market_events(
    synthetic_btc,
    event_type="crash",
    probability=0.02  # 2% chance per timestep
)

# Add pump events
data_with_pumps = generator.add_market_events(
    synthetic_btc,
    event_type="pump",
    probability=0.01
)

# Add volatility spikes
data_with_vol = generator.add_market_events(
    synthetic_btc,
    event_type="volatility",
    probability=0.05
)

Generate Order Book Data

# Generate order book snapshot
order_book = generator.generate_order_book(
    mid_price=50000,
    spread=0.001,
    depth=20,
    volume_range=(0.1, 10)
)

print(f"Best Bid: {order_book['bids'].iloc[0]['price']:.2f}")
print(f"Best Ask: {order_book['asks'].iloc[0]['price']:.2f}")
print(f"Spread: {order_book['spread']*100:.2f}%")

Data Augmentation Pipeline

# Complete augmentation pipeline
def augment_training_data(real_data, augmentation_factor=2):
    """Augment real data with synthetic samples"""

    generator = CryptoSyntheticGenerator(
        SyntheticDataConfig(n_samples=len(real_data) * augmentation_factor)
    )

    # Generate base synthetic data
    synthetic = generator.generate_ohlcv(base_data=real_data)

    # Add various augmentations
    augmented_sets = []

    # 1. Add noise augmentation
    noisy_data = generator.augment_with_noise(real_data, noise_level=0.02)
    augmented_sets.append(noisy_data)

    # 2. Add synthetic with events
    synthetic_events = generator.add_market_events(synthetic, "volatility", 0.1)
    augmented_sets.append(synthetic_events)

    # 3. Combine all
    combined = pd.concat([real_data] + augmented_sets, ignore_index=True)

    # Validate quality
    quality = generator.validate_quality(combined, real_data)
    print(f"Augmented data quality score: {quality['quality_score']:.3f}")

    return combined

# 1. Embedding & Recovery: Real data ↔ Latent space
# 2. Generator & Supervisor: Generate realistic sequences
# 3. Discriminator: Distinguish real from fake

🔍 Best Practices

1. Data Preprocessing

Always normalize data before training
Remove outliers for stable training
Ensure temporal ordering

2. Model Selection

TimeGAN: Best for time series with complex dynamics
Statistical: Fast baseline, good for simple augmentation

3. Quality Control

Always validate against real data statistics
Check temporal consistency
Verify OHLC relationships
Test on downstream tasks
