sagan-trade 0.7.4

Strategic High-Throughput Symbolic Trading Engine with iterative R2 fitting, FunctionGemma discovery, and Asymmetric Convexity risk management.

Sagan Trade

High-fidelity symbolic mathematical engine for institutional alpha generation.

Sagan Trade replaces black-box neural networks with transparent, human-readable mathematical equations discovered via FunctionGemma. It combines the precision of Symbolic Regression with the robustness of Asymmetric Convexity risk management.

🏛️ Institutional Benchmarking

Sagan Trade has been rigorously tested across 5 years of historical market regimes, accounting for institutional trading fees and liquidity constraints.

Long-Term Resilience (5-Year Rolling Audit)

Benchmark: 20-Ticker Diversified Portfolio (Tech, Finance, Energy, Consumer).

Metric	Gross of Fees	Net of Fees (5bps)	S&P 500 (B&H)
Annualized Return	33.27%	12.98%	14.50%
Sharpe Ratio	2.11	1.06	0.85
Max Drawdown	-6.91%	-7.30%	-23.90%
Total Cumulative	426.11%	102.46%	96.80%

[!IMPORTANT] Statistical Significance: The symbolic engine achieves a p-value of 0.0182, indicating that its outperformance against legacy TFT-PINN models is statistically significant at the 98% confidence level.

🔬 Core Architecture

1. Symbolic Discovery (FunctionGemma)

Instead of weight matrices, Sagan discovers market invariants in the form of mathematical expressions.

• Precision: Fits variables to $R^2 > 0.95$ using basis functions (Polynomial, Fourier).
• Explainability: Every trade is backed by a human-readable formula, e.g., (Close * 0.5) + log(Volume).

2. Asymmetric Convexity Engine

Sagan utilizes a non-linear risk management framework inspired by high-frequency market makers:

• Downside Convexity: Exponentially scales exposure based on momentum-volatility asymmetry.
• Adaptive Kelly Sizing: Drawdown-aware fractional Kelly scaling to ensure capital preservation.
• Asymptotic Shield: Quadratic drawdown protection creates a hard floor on portfolio risk.

🚀 Quick Start

Installation

pip install sagan-trade

Alpha Generation & Execution

import sagan
from sagan.portfolio import AsymmetricRiskEngine

# 1. Discover a symbolic formula for a ticker
model_id = sagan.train(["AAPL"], signals=["Close", "RSI", "Volume"])

# 2. Initialize the SOTA Risk Engine
risk_engine = AsymmetricRiskEngine(target_vol=0.15, max_drawdown_limit=0.075)

# 3. Generate Signal & Predictive Formula
result = sagan.predict()
print(f"Signal: {result['signal']}")
print(f"Formula: {result['formula']}")
