You possess deep, master-level knowledge of the `Thalex_modular` project, its Clean Architecture implementation, and the advanced mathematical models that drive its quoting engine. ## Project Domain Knowledge ### Core Architecture (Clean Architecture / Ports & Adapters) The project adheres to strict separation of concerns to ensure performance and maintainability: - **Domain Layer** (`src/domain/`): Pure business logic and mathematical models. - [`entities/`](src/domain/entities/): Core dataclasses (Order, Ticker, MarketState, PNL) with `__slots__` for performance. - [`market/regime_detector.py`](src/domain/market/regime_detector.py): Advanced market classification (Quiet, Volatile, Trending, Illiquid). - [`strategies/avellaneda.py`](src/domain/strategies/avellaneda.py): Heuristic Avellaneda-Stoikov implementation with regime-aware adjustments. - [`interfaces.py`](src/domain/interfaces.py): Abstract definitions for Gateways, Strategies, and Risk Managers. - **Use Cases Layer** (`src/use_cases/`): Application orchestration. - [`quoting_service.py`](src/use_cases/quoting_service.py): The main trading engine. Orchestrates Market Data → Signals → Regime Detection → Strategy → Execution. Features lock-protected, margin-optimized order reconciliation. - **Adapters Layer** (`src/adapters/`): External system integrations. - [`exchanges/thalex_adapter.py`](src/adapters/exchanges/thalex_adapter.py): High-performance Thalex API integration. - [`storage/timescale_adapter.py`](src/adapters/storage/timescale_adapter.py): Batch-optimized persistence for 1m resolution data using TimescaleDB. - **Data Ingestion Layer** (`src/data_ingestion/`): Pipeline for external market intelligence. - [`options_pipeline.py`](src/data_ingestion/options_pipeline.py): Intelligence gatherer that fetches ATM Call/Put data to calculate "Expected Move" (EM) from Straddle prices. ### Technical Stack & Data Persistence - **Convex**: The primary real-time persistence layer for dashboard state, mutations, and discovery caching. - **TimescaleDB**: Used for high-resolution (1m) historical market data and backfilling (stored in hypertables). - **FastAPI**: Serves simulation and analytics data to the frontend via high-performance endpoints. - **SvelteKit**: The modern, highly aesthetic web dashboard for trading analytics. ### Key Mathematical & HFT Models 1. **Expected Move (EM) Calculation**: - Uses ATM Straddle (Call + Put) for target expiries (typically >3 days). - `EM ≈ Straddle Price * 0.85`. - Used as a volatility benchmark to calibrate spreads and skew. 2. **Market Regime Detection**: - **Quiet**: Standard A-S market making. - **Volatile**: Widened spreads, increased gamma (risk aversion). - **Trending**: Aggressive inventory skew to avoid "getting run over." - **Illiquid**: Reduced order sizes and widened spreads to account for toxic flow. 3. **Avellaneda-Stoikov (A-S) Heuristics**: - Optimal Spread: Base fee coverage + risk aversion (gamma) + volatility component + inventory risk component. - Reservation Price: Skewed based on inventory delta and Expected Move offsets. ### Critical Performance Standards - **Latency Sensitivity**: Every microsecond counts in order reconciliation. - **Margin Optimization**: Cancels unnecessary orders BEFORE placing new ones to minimize margin lock-up. - **Async Efficiency**: Zero synchronous I/O in the hot path. Use `asyncio` for all network and database calls. ## Code Change Guidelines 1. **Domain Purity**: Never import external libraries (except NumPy) into `src/domain/`. 2. **Interface Compliance**: All new adapters MUST strictly implement the `interfaces.py` contracts. 3. **Risk-First**: Changes to `RiskManager` or `quoting_service.py` reconciliation logic require 100% test coverage. 4. **Configuration**: All parameters (gamma, spread, EM multipliers) MUST flow via environment variables or central configuration. 5. **Memory Efficiency**: Use `__slots__` for all entities in `src/domain/entities/`. ## Anti-Patterns to Avoid - **Hardcoding Expiries**: Use the dynamic discovery logic in `options_pipeline.py`. - **Sync DB Calls**: Never use synchronous JDBC/psycopg2 in the quoter loop; use the `TimescaleDBAdapter` (asyncpg). - **Ignoring Margin**: Always reconciliation orders by matching price/size to avoid churn. ## Continuous Knowledge Protocol When exploring this codebase, always check: 1. `GEMINI.md`: For the latest strategic directives. 2. `src/domain/entities/`: For any schema changes. 3. `config/`: For updated trading parameters.
