*What makes it different:*
Most trading libraries are either: - Too slow (Backtrader: ~5ms/point, Zipline: ~10ms/point) - Missing advanced math (no quantum finance, chaos theory, optimal execution models) - No AutoML pipeline (QuantConnect has basic ML but no AutoML) - No GPU acceleration
Qantify addresses all of these.
*Performance:* - 0.008ms per data point (50-100x faster than alternatives) - GPU acceleration: 2-3x speedup on compatible hardware - 1767+ comprehensive tests, 100% code coverage - 106K+ lines of code
*Advanced Math Models* (what hedge funds use):on # GARCH volatility modeling from qantify.math.econometrics import GARCHModel garch = GARCHModel(returns) vol_forecast = garch.forecast(horizon=10)
# Heston stochastic volatility from qantify.math.stochastic import HestonProcess, MonteCarloEngine heston = HestonProcess(v0=0.04, theta=0.04, kappa=2.0, sigma=0.3, rho=-0.7) mc = MonteCarloEngine(process=heston) paths = mc.simulate(n_paths=10000, n_steps=252)
# Optimal execution (Almgren-Chriss) from qantify.math.execution import AlmgrenChrissOptimalExecution execution = AlmgrenChrissOptimalExecution( initial_position=10000, time_horizon=timedelta(hours=4), risk_aversion=1e-6 ) optimal_schedule = execution.compute_schedule()
# Advanced cointegration (statistical arbitrage) from qantify.math.stat_arb import JohansenTest, KalmanHedgeRatioEstimator*Unique features* (not found in competitors): - Quantum finance models - Chaos theory applications - Complexity theory - Information theory - Game theory models
*ML/AutoML Pipeline* (end-to-end):thon from qantify.ml import AutoMLRunner, create_features
# Auto-generate 100+ features features = create_features( df, feature_sets=["trend", "momentum", "volatility", "statistical"], windows=(14, 55, 200) )
# Automated model selection with walk-forward validation runner = AutoMLRunner( search="bayesian", # or "grid", "random", "hyperopt" walk_forward=True, # Time-series aware validation test_size=0.25 )
results = runner.run(features, target) # Automatically tests: RF, GBM, XGBoost, LightGBM # Selects best model with proper time-series validation*ML Features:* - Reinforcement learning (DQN, Q-learning, Policy gradients) - Advanced neural networks (LSTM, GRU, Transformers, Attention) - Model drift monitoring - Feature selection (SHAP, mutual information) - Experiment tracking (MLflow, W&B integration)
*Quick example:* from qantify.data import get_candles from qantify.signals import rsi from qantify.backtest.vectorized import run_vectorized
df = get_candles("binance", "BTCUSDT", "1h", limit=1000) df['rsi'] = rsi(df['close'], period=14)
result = run_vectorized( prices=df["close"], long_signal=df["rsi"] < 30, short_signal=df["rsi"] > 70, allocation=0.5 )
print(f"Sharpe: {result.metrics.sharpe:.2f}")*Real benchmarks:* - Backtest speed: < 0.1s (5000 points) vs QuantConnect's ~5-10s - GPU speedup: 2-3x (tested on RTX 3070) - ML accuracy: Market regime 74.3%, Volatility prediction 68.7%
*Why I built it:* I needed advanced math models (GARCH, Heston, optimal execution) combined with modern ML pipelines, all in one library. Existing solutions either lacked the math depth or the ML integration.

I'd love feedback from the HN community. What features would you find most useful? What am I missing?
Built with Python 3.10+, async/await everywhere, modular architecture. Completely open-source and free for personal/research use.
