Description: This strategy applies the Avellaneda-Stoikov (A-S) model to generate buy and sell signals for underlying assets based on option pricing theory. The A-S model estimates bid and ask quotes for options contracts considering factors like volatility (sigma), time to expiration (T), and risk aversion (gamma).
Key Concepts: Avellaneda-Stoikov Model: A mathematical framework for option pricing that incorporates volatility, time decay, and risk tolerance. Bid-Ask Quotes: The theoretical buy and sell prices for an option contract. Inventory Management: The strategy tracks its long or short position based on signals.
How it Works: A-S Model Calculation: The avellanedaStoikov function calculates bid and ask quotes using the underlying asset's closing price, user-defined parameters (gamma, sigma, T, k, and M), and a small fee (adjustable). Signal Generation: The strategy generates long signals when the closing price falls below the adjusted bid quote and short signals when it exceeds the adjusted ask quote. Trade Execution: Buy and sell orders are triggered based on the generated signals (long for buy, short for sell). Inventory Tracking: The strategy's net profit reflects the current inventory level (long or short position).
Customization: Gamma (γ): Controls risk aversion in the A-S model (higher values imply lower risk tolerance). Sigma (σ): Represents the underlying asset's expected volatility. T: Time to expiration for the hypothetical option (defaults to a short-term option). k: A constant factor in the A-S model calculations. M: Minimum price buffer for buy/sell signals (prevents excessive churn).
Important Note: This strategy simulates option pricing behavior for a theoretical option and does not directly trade options contracts. Backtesting results may not reflect actual market conditions.
Further Considerations: The 0.1% fee is a placeholder and may need adjustment based on real-world trading costs. Consider using realistic timeframes for T (e.g., expiry for a real option)
