It calculates the *predicted percentage return* from this price prediction and estimates prediction *uncertainty* based on the standard deviation of Monte Carlo dropout predictions. It also extracts recent *momentum* and *volatility* features. These values, along with a risk proxy (`z_proxy`), form the **5-dimensional state** input (`[predicted_return, mc_unscaled_std_dev, z_proxy, momentum_5, volatility_20]`) to the SAC reinforcement learning agent, which determines optimal position sizing (-1 to +1) using a **squashed Gaussian policy** and **automatic entropy tuning**. +The core idea is to decouple prediction and action: +1. A **GRU model** (primarily v3 architecture) forecasts future log-returns (μ̂) and ternary class probabilities (p_down, p_flat, p_up). +2. The **probability forecast** is calibrated using Vector Scaling (or Temperature Scaling for binary cases). +3. A **SAC agent** observes the GRU outputs (derived features like 'edge'), its own current position, and potentially other state variables (normalized using `MeanStdFilter`) to determine the optimal **position size** (-1 to +1). -The system incorporates efficiency improvements by pre-computing GRU predictions and uncertainties before generating SAC experiences or running the backtest. It includes detailed backtesting, performance reporting, and visualization capabilities, including **SAC training loss plots**. +This approach aims for a robust system where the RL agent focuses solely on risk management (sizing) based on the predictor's signals. -## System Design +## V3 Features -The system integrates a GRU predictor and a Simplified SAC agent within a backtesting framework. +This version incorporates significant revisions, including: -### 1. Data Flow & Processing +* **Data/Labeling:** Soft binary labels, optional ternary (up/flat/down) labels. +* **Features:** Potential use of volatility-normalized returns, cyclical time features, and technical indicators. +* **GRU v3 Model:** GRU -> Attention -> LayerNorm architecture predicting continuous log-return (`mu`) and ternary direction classification logits (`dir3`). +* **Calibration:** Vector Scaling for ternary outputs; Temperature Scaling as an option for binary classification. +* **SAC Stabilization:** Reward scaling, state normalization (`MeanStdFilter`), adjusted target entropy calculation, action magnitude penalty, optional oracle buffer seeding. +* **Metrics & Validation:** Edge-filtered accuracy metric, baseline model checks, backtest performance validation gates (Sharpe, Max Drawdown), re-centered Sharpe ratio. +* **Configuration:** Centralized `config.yaml` controls pipeline stages, model versions, hyperparameters. +* **Output Contract:** Standardized output structure via `IOManager` and `LoggerSetup` for reproducibility. +* **Testing:** Unit tests and an output contract smoke test (`tests/test_output_contract.py`). +* **Documentation:** This README and `docs/v3_changelog.md`. -1. **Loading:** Raw 1-minute OHLCV data is loaded from the SQLite database directory specified in `main.py` (e.g., `downloaded_data/`) using `src.data_pipeline.load_data_from_db` which utilizes `src.crypto_db_fetcher.CryptoDBFetcher`. -2. **Splitting:** Data is chronologically split into training (60%), validation (20%), and test (20%) sets using `src.data_pipeline.create_data_pipeline`. -3. **GRU Training / Loading (on Train/Validation Sets):** - * If `TRAIN_GRU_MODEL` is `True`: - * *Preprocessing*: `TradingSystem._preprocess_data_for_gru_training` calculates V6 features plus basic return features (`calculate_v6_features`) on the raw train/val data. It determines the future *price* target (`prediction_horizon` steps ahead) and aligns features, targets (prices), and the *unscaled* starting close prices needed for return calculation. - * *Scaling*: Within `TradingSystem.train_gru`, a `StandardScaler` is fitted *only* on the training features. A `MinMaxScaler` is fitted *only* on the training future *price* targets. Train and validation features/targets are scaled using these fitted scalers. - * *Sequence Creation*: `src.data_pipeline.create_sequences_v2` creates input sequences `(batch, sequence_length, num_features)` and corresponding scaled target prices using the scaled features/targets and the unscaled start prices. - * *Model Training*: `CryptoGRUModel.train` builds the V6-style GRU model (if not already built) and trains it using Mean Squared Error (MSE) loss on the scaled sequences. Callbacks monitor `val_rmse` for early stopping and model checkpointing. The best model (`best_model_reg.keras`) and the fitted scalers (`feature_scaler.joblib`, `y_scaler.joblib`) are saved. - * If `LOAD_EXISTING_SYSTEM` is `True` and `TRAIN_GRU_MODEL` is `False`: - * Attempts to load a pre-trained GRU model and scalers. If `GRU_MODEL_LOAD_RUN_ID` is set in `main.py`, it loads the GRU from that specific run ID's directory (`gru_sac_predictor/models/run_`); otherwise, it attempts to load from the default `MODEL_SAVE_PATH` (expecting the model and scalers to be directly in that path). - * **Note:** SAC model loading is handled *separately* based on the `LOAD_SAC_AGENT` flag and the `GRU_MODEL_LOAD_RUN_ID` setting (see Model Loading/Training section in `main.py` for details). -4. **SAC Training (on Validation Set):** - * **Training Loop:** The training process runs for a fixed number of epochs (`SAC_EPOCHS`). - * **Experience Generation** (`TradingSystem.generate_trading_experiences`): - * **Efficiency:** Pre-computes all required GRU outputs (predicted returns, uncertainties) for the entire validation set by calling `CryptoGRUModel.evaluate` *once*. - * **State Extraction:** Extracts pre-computed GRU outputs and relevant features (`momentum_5`, `volatility_20`) from the validation features dataframe. - * **Experience Format:** Iterates through the pre-computed results. Forms the 5D state `s_t = [pred_return_t, uncertainty_t, z_proxy_t, momentum_5_t, volatility_20_t]` (where `z_proxy` uses the position *before* the action). The SAC agent (`SimplifiedSACTradingAgent.get_action`) provides a *non-deterministic* action `a_t` and `log_prob`. The next state `s_{t+1}` is constructed similarly (using `action` for `z_proxy`). A reward `r_t = action * actual_return - cost` is calculated. The transition `(s_t, a_t, r_t, s_{t+1}, done)` is stored. - * **Note:** Experience sampling strategies (recency bias, stratification) defined in `experience_config` are currently *not* implemented in `generate_trading_experiences` but the configuration remains. - * **Agent Training** (`TradingSystem.train_sac` calls `SimplifiedSACTradingAgent.train`): Iterates for `SAC_EPOCHS`. In each epoch, the agent performs one training step. Batches are sampled from the replay buffer. Actor and Critic networks are updated using the SAC algorithm with automatic alpha tuning. Agent uses `store_transition` to add experiences to its internal NumPy buffer. - * **History Plotting:** After successful training, `plot_sac_training_history` is called to generate and save a plot of actor and critic losses. -5. **Backtesting (on Test Set):** - * *Pre-computation* (`ExtendedBacktester.backtest`): Preprocesses test data, scales, creates sequences, calls `CryptoGRUModel.evaluate` once for GRU outputs, and extracts required features (`momentum_5`, `volatility_20`). - * *State Generation*: Constructs the 5D state `s_t = [pred_return, uncertainty, z_proxy, momentum_5, volatility_20]` using pre-computed results and the current position. - * *Action Selection*: The trained `SimplifiedSACTradingAgent` selects a *deterministic* action `a_t` (unpacking the tuple returned by `get_action`). - * *Portfolio Simulation*: Calculates PnL based on the previous position, actual return, and transaction costs. - * *Logging*: Records detailed metrics, trade history, and timestamps. -6. **Evaluation:** - * *Performance Metrics*: `ExtendedBacktester._calculate_performance_metrics` computes overall portfolio metrics (Sharpe, Sortino, Drawdown, correlations, etc.) and Buy & Hold benchmark metrics. - * *Visualization*: `ExtendedBacktester.plot_results` generates a 3-panel plot: GRU Predictions vs Actual Price (with uncertainty), SAC Actions (Position Size), and Portfolio Value vs Buy & Hold (with trade markers). - * *Reporting*: `ExtendedBacktester.generate_performance_report` creates a detailed Markdown report. +## System Design (v3) -### 2. Core Components & Inputs/Outputs +The system is orchestrated by `run.py`, which sets up logging and I/O via `LoggerSetup` and `IOManager`, then instantiates and executes the `TradingPipeline` class (`src/trading_pipeline.py`).

Adds uncertainty-scaled noise during exploration. - * `store_transition()`: Adds experience to internal NumPy buffer. - * `train()`: Updates agent using buffer samples (internally handles batch size). Uses `@tf.function` for performance. - * `save()` / `load()`: Handles Actor/Critic weights (`.weights.h5`), potentially `alpha.npy`. - * **Note:** Models and optimizers are built explicitly during `__init__` using dummy inputs to prevent TensorFlow graph mode issues. -* **`src.trading_system.TradingSystem`**: Integrates GRU and SAC. Manages training pipelines, feature calculation, experience generation. -* **`src.trading_system.ExtendedBacktester`**: Performs efficient backtesting using pre-computed GRU outputs, calculates metrics, plots results, generates reports. -* **`src.trading_system.plot_sac_training_history`**: Generates plot for SAC actor/critic losses during training. +```mermaid +%%{init: {'themeVariables': { 'fontSize': '26px' }}}%% +flowchart TD + subgraph Initialization + A["run.py: Init Logger/IOManager"] --> B[TradingPipeline]; + end + subgraph DataPreparation ["Data Preparation"] + B --> C["Load Data (DataLoader)"]; + C --> D["Engineer Features (FeatureEngineer)"]; + D --> E["Define Labels (Binary/Ternary)"]; + E --> F["Split Data (Train/Val/Test)"]; + F --> G["Scale Features (StandardScaler)"]; + G --> I["Baseline Check (BaselineChecker)"]; + I -- Pass --> H["Select/Prune Features"]; + H --> J[Create Sequences]; + end + subgraph PredictionModel ["Prediction Model (GRU)"] + J --> K["Train/Load GRU Model (GRUModelHandler)"]; + K --> L["Calibrate Probabilities (Calibrator/VectorCalibrator)"]; + L --> M["Validation Gate: Edge Acc Check"]; + end + subgraph ActionModel ["Action Model (SAC)"] + M -- Pass --> N["Train/Load SAC Agent (SACTrainer)"]; + end + subgraph Evaluation + N --> O["Run Backtest (Backtester)"]; + O --> P["Save Results (Backtester/IOManager)"]; + P --> Q["Validation Gate: Backtest Perf Check"]; + end +``` -### 3. Model Architectures +*Diagram outlines the v3 pipeline flow including setup, core stages, and validation gates.* -* **GRU (`src.gru_predictor.CryptoGRUModel._build_model`)**: V6 Architecture. - * Input -> GRU(100) -> Dropout(0.2) -> Dense(1, linear). - * Compiled with Adam (LR=0.001), MSE loss. -* **Simplified SAC (`src.sac_agent_simplified.SimplifiedSACTradingAgent`)**: - * **Actor Network**: MLP `(state_dim=5)` -> Dense(64, relu) -> [BN] -> Dense(64, relu) -> [BN] -> [Residual] -> Dense(1, name='mu'), Dense(1, name='log_std').

Uses Huber loss for critics. `@tf.function` used for update steps (`_update_critics`, `_update_actor_and_alpha`). +### Detailed Steps (Reflecting Current Implementation) -### 4. Features & State Representation +* **A (`run.py`):** Parses command-line arguments (`--config`, `--log-level`), generates a unique `run_id`, loads the specified `config.yaml`, initializes `IOManager` and `LoggerSetup` for managing outputs and logs, logs a system banner, and instantiates `TradingPipeline`, passing the configured `io_manager`. +* **C (`TradingPipeline.load_and_preprocess_data`):** Uses `DataLoader` to load the specified Parquet data files. Performs initial cleaning (e.g., handling NaNs, setting index). Saves `preprocess_summary.txt` and a preview (`head_preprocessed.*`) via `IOManager`. +* **D (`TradingPipeline.engineer_features`):** Employs `FeatureEngineer` to compute additional features (e.g., technical indicators, volatility-normalized returns, cyclical features) based on the raw price data. +* **E (`TradingPipeline.define_labels_and_align`):** Calculates target variables (future log-returns). Defines classification labels (soft binary or ternary based on `gru.use_ternary` and `gru.flat_sigma_multiplier`). Aligns features and labels. Saves `feature_corr_heatmap.png`. +* **F (`TradingPipeline.split_data`):** Splits the data chronologically into training, validation, and test sets based on configured percentages or dates. Saves `label_histogram.png`. +* **G (`TradingPipeline.scale_features`):** Fits a `StandardScaler` on the training set features. Saves the scaler object (`feature_scaler_{run_id}.joblib`). Transforms features in all splits (train, val, test). +* **I (`TradingPipeline.run_baseline_checks`):** Uses `BaselineChecker` to train a simple baseline model (e.g., Logistic Regression) on the *scaled, non-sequential* training data and evaluate it on the validation set. Saves `baseline1_report.txt`. **Exits if the baseline confidence interval lower bound (CI LB) on accuracy is below a threshold (e.g., 0.52)**. +* **H (`TradingPipeline.select_and_prune_features`):** Selects the final set of features based on a predefined list or criteria. Saves the final list (`final_whitelist.json`). Removes non-selected features from the *scaled, non-sequential* data splits. +* **J (`TradingPipeline.create_sequences`):** Transforms the *pruned, scaled* time-series data splits into overlapping sequences suitable for input to the GRU model, using specified sequence length. +* **K (`TradingPipeline.train_or_load_gru`):** Depending on `control.train_gru`, either trains a new GRU model (`model_gru_v3.py` if `control.use_v3` is true) using the *sequenced* training/validation data via `GRUModelHandler`, or loads a pre-trained model. Saves the trained model (`gru_model_v3_{run_id}.keras`), training history (`gru_history.csv`), and plots learning curves (`gru_learning_curve.png`). +* **L (`TradingPipeline.calibrate_probabilities`):** Takes the raw classification outputs (logits) from the GRU model on the validation set and calibrates them to better reflect true probabilities. Uses either `Calibrator` (Temperature Scaling) or `VectorCalibrator` (Vector Scaling) based on `calibration.method`. Saves calibration parameters (`calibration_{temp/vector}_{run_id}.npy`) and plots reliability curves (`reliability_curve_*.png`). +* **M (`TradingPipeline._perform_edge_filtered_accuracy_check`):** Calculates the accuracy of the calibrated GRU predictions on the validation set, but only considering predictions where the predicted probability (or 'edge') exceeds `calibration.edge_threshold`. **Exits if edge-filtered accuracy is below a threshold (e.g., 0.60)**. +* **N (`TradingPipeline.train_or_load_sac`):** Depending on `control.train_sac`, either trains a new SAC agent using `SACTrainer` or loads a pre-trained agent. The `SACTrainer` interacts with the `TradingEnv`, which uses the trained GRU model to provide market predictions as part of the agent's state.

Saves the final `run_config.yaml`. -* **GRU Features:** Uses the V6 feature set plus basic past returns (see `calculate_v6_features`). Cyclical time features (`hour_sin`, `hour_cos`) are added *before* data splitting. -* **SAC State (`state_dim=5`):** - 1. `predicted_return`: GRU predicted percentage return for the next period. - 2. `uncertainty`: GRU MC dropout standard deviation (unscaled). - 3. `z_proxy`: Risk proxy, calculated as `current_position * volatility_20`. - 4. `momentum_5`: 5-minute return (`return_5m` feature). - 5. `volatility_20`: 20-day volatility (`volatility_14d` feature, name mismatch intended). -* **Scaling:** Features for GRU scaled with `StandardScaler`. Target price for GRU scaled with `MinMaxScaler`. SAC state components are used directly without separate scaling. +## Core Components Architecture -### 5. Evaluation +This section details the architecture and purpose of key modules within the system. -* **GRU Model:** Evaluated using RMSE loss on validation set. Callbacks monitor `val_rmse`. Plots compare predicted vs actual price. -* **SAC Agent & Overall System:** Evaluated via the `ExtendedBacktester` metrics (Sharpe, Sortino, Max Drawdown, correlations, etc.), plots (Portfolio vs B&H, Actions), and a final Markdown report. SAC training progress monitored via saved loss plots (`sac_training_history_.png`). +### 1. Data Handling (`DataLoader`, `FeatureEngineer`) + +* **`DataLoader` (`src/data_loader.py`):** Responsible for loading raw market data (OHLCV - Open, High, Low, Close, Volume) from specified Parquet files (`_.parquet`). Handles basic preprocessing like setting a DatetimeIndex and potentially initial NaN handling. +* **`FeatureEngineer` (`src/feature_engineer.py`, `src/features.py`):** Takes the preprocessed OHLCV data and generates a richer feature set for the predictive model. This can include: + * **Technical Indicators:** Moving averages, RSI, MACD, Bollinger Bands, etc. + * **Volatility Features:** ATR (Average True Range), realized volatility. + * **Return-based Features:** Log returns over different periods, potentially volatility-normalized returns. + * **Time/Cyclical Features:** Day of week, hour of day, encoded cyclically using sine/cosine transforms. + * **Target Definition:** Calculates future log returns (the regression target `mu_target`) and derives classification labels (binary or ternary) based on thresholds (potentially dynamic using `flat_sigma_multiplier`). + +### 2. GRU Predictor (`model_gru_v3.py`, `GRUModelHandler`) + +* **`model_gru_v3.py`:** Defines the core GRU v3 network architecture using TensorFlow/Keras. + * **Input:** Sequences of scaled features `(batch_size, sequence_length, num_features)`. + * **Architecture:** + 1. **GRU Layers:** One or more GRU layers to capture temporal dependencies in the input sequences. + 2. **Attention Mechanism:** An attention layer (optional, configurable) applied to the GRU outputs to allow the model to focus on more relevant time steps within the sequence. + 3. **Layer Normalization:** Applied after attention (or GRU if no attention) for stabilization. + 4. **Output Heads:** Two separate dense output layers: + * `mu`: Predicts the continuous future log-return (single output neuron, linear activation). + * `dir3`: Predicts the logits for the ternary classification (down, flat, up) (3 output neurons, linear activation). If `gru.use_ternary` is false, this might adapt to binary classification or be ignored downstream. + * **Loss Function:** A combined loss is typically used during training: + * Mean Squared Error (MSE) for the `mu` regression output. + * Categorical Cross-Entropy (potentially with Focal Loss modification via `gru_v3.focal_gamma`) for the `dir3` classification output. +* **`GRUModelHandler` (`src/gru_model_handler.py`):** Manages the training lifecycle of the GRU model. Handles model compilation (optimizer, loss functions, metrics), data preparation (using `tf.data.Dataset` for efficiency), training loops (including early stopping), model saving/loading, and prediction generation. + +### 3. Probability Calibration (`Calibrator`, `VectorCalibrator`) + +* **Need:** Neural network outputs (logits/softmax) often don't directly represent true probabilities (i.e., they can be over/under-confident). Calibration adjusts these outputs post-training to be more reliable. +* **`Calibrator` (`src/calibrator.py`):** Implements Temperature Scaling. Learns a single scalar parameter (temperature `T`) on the validation set logits. Calibrated probabilities are obtained by dividing logits by `T` before applying softmax. Primarily suitable for binary or multi-class problems where miscalibration is consistent across classes. +* **`VectorCalibrator` (`src/calibrator_vector.py`):** Implements Vector Scaling. Learns a vector (matrix `W` and bias `b`) on the validation set logits. Calibrated logits are obtained via `logit' = W * logit + b`. More flexible than Temperature Scaling and generally preferred for multi-class (like ternary) classification. + +### 4. SAC Agent (`sac_agent.py`, `SACTrainer`, `TradingEnv`) + +* **Goal:** To learn an optimal position sizing strategy based on the GRU predictor's signals and the agent's current state. +* **`sac_agent.py`:** Defines the Soft Actor-Critic (SAC) agent components: + * **Actor Network:** Maps state to a probability distribution over actions (position size -1 to +1). Typically outputs parameters (mean, std dev) of a squashed Gaussian distribution. + * **Critic Networks (Q-Functions):** Estimate the expected future return (Q-value) for a given state-action pair. SAC uses two critics (and target critics) to mitigate overestimation bias. + * **Alpha (Entropy Temperature):** Controls the trade-off between maximizing expected return and maximizing policy entropy (encouraging exploration). Can be a fixed value or learned automatically (common). +* **`TradingEnv` (`src/trading_env.py`):** An OpenAI Gym-style environment simulating the trading process: + * **State:** The observation provided to the agent at each time step. Typically includes: + * Calibrated probabilities or derived 'edge' from the GRU model. + * The agent's current position (-1 to +1). + * Potentially other relevant features (e.g., recent volatility). + * **Action:** The position size chosen by the SAC agent (-1 to +1). + * **Reward:** Calculated based on the portfolio's change in value from one step to the next, considering the chosen position and market movement. May include: + * `environment.reward_scale` multiplier. + * Penalty for large actions (`environment.action_penalty_lambda`). + * Transaction costs (slippage, commissions - handled in `Backtester` usually, but could be in Env). + * **Normalization:** Uses `MeanStdFilter` (from `src/utils/running_stats.py`) if `sac.use_state_filter` is true to normalize the state variables, which is crucial for stable RL training. +* **`SACTrainer` (`src/sac_trainer.py`):** Orchestrates the SAC training loop: + * Manages the interaction between the agent and the environment. + * Stores experiences (state, action, reward, next_state) in a Replay Buffer. + * Samples batches from the buffer to update the Actor, Critic, and Alpha parameters. + * Handles state normalization filter updates. + * Implements "Oracle Seeding" (`sac.oracle_seeding_pct`): Pre-fills a portion of the replay buffer with transitions generated by a simple heuristic policy (e.g., size position based directly on predicted edge) to potentially speed up initial learning. + * Saves/loads agent models and the state filter. + +### 5. Evaluation (`Backtester`, `BaselineChecker`) + +* **`Backtester` (`src/backtester.py`):** Evaluates the combined GRU+SAC system on unseen test data. + * Takes the trained GRU model, calibrated outputs, and the trained SAC agent. + * Iterates through the test set step-by-step. + * At each step: + 1. Gets the GRU prediction. + 2. Constructs the state for the SAC agent. + 3. Gets the position size action from the SAC agent. + 4. Calculates the resulting portfolio performance, incorporating realistic factors like: + * Transaction Costs (configurable slippage and commission rates). + * Position constraints. + * Calculates and reports various performance metrics (`src/metrics.py`): Sharpe Ratio, Sortino Ratio, Max Drawdown, Calmar Ratio, Win Rate, Profit Factor, etc. + * Generates plots: Equity curve, drawdown periods, position changes, confusion matrix (based on predicted vs. actual moves when a position was taken). +* **`BaselineChecker` (`src/baseline_checker.py`):** Provides an initial sanity check before extensive GRU/SAC training. + * Trains a simple, fast model (e.g., Logistic Regression) on the prepared features and labels. + * Evaluates its performance (e.g., Accuracy, AUC) on the validation set. + * Calculates a confidence interval for the primary metric. + * The pipeline uses this to gate further execution, ensuring the features/labels have at least some minimal predictive power before committing to computationally expensive training. + +### 6. Orchestration & Utilities (`TradingPipeline`, `IOManager`, `LoggerSetup`) + +* **`TradingPipeline` (`src/trading_pipeline.py`):** The main class that coordinates the entire workflow, calling the different components in sequence as outlined in the "Detailed Steps" section. Reads configuration, manages data flow between steps, and implements validation gates. +* **`IOManager` (`src/io_manager.py`):** Handles all file input/output operations. Creates standardized directory structures based on `run_id`, saves/loads models, dataframes (CSV/Parquet), scaler objects, configuration files, plots, and text reports. Ensures outputs are organized and reproducible. +* **`LoggerSetup` (`src/logger_setup.py`):** Configures Python's standard `logging` module.

Data & Labeling (`config.data`, `config.gru`)\n\n* **Volatility-Aware Sampling (Task 1.1):**\n * Added optional sampling in `DataLoader` to focus on higher volatility periods.\n * Config: `data.vol_sampling` (bool), `data.vol_window` (int), `data.vol_quantile` (float).\n* **Soft Binary Labels (Task 1.2):**\n * Option to use smoothed labels (e.g., \[0.1, 0.9]) instead of hard {0, 1} for binary classification.\n * Config: `data.label_smoothing` (float, 0.0 to disable).\n* **Ternary Direction Labels (Task 1.3):**\n * Added option for \"up\" / \"flat\" / \"down\" classification.\n * \"Flat\" defined dynamically based on forward return volatility.\n * Config: `gru.use_ternary` (bool), `gru.flat_sigma_multiplier` (float).\n\n### 2. Feature Engineering (`config.features` - conceptual)\n\n* **Volatility-Normalized Return (Task 2.1):**\n * Added `vola_norm_return(df, k)` function.\n * Calculated for k=15, k=60 and added to default features (`vola_norm_return_15`, `vola_norm_return_60`).\n* **Weekly Fourier Features (Task 2.2):**\n * Added `week_sin`, `week_cos` to capture weekly seasonality.\n * Added to default features.\n* **MACD Removal (Task 2.3):**\n * Removed `MACD` and `MACD_signal` calculation and from `minimal_whitelist`.\n* **VIF Skip Logic (Task 2.5):**\n * Conceptual: Tests added assuming a `config.features.skip_vif` flag could be implemented in `FeatureEngineer.select_features`.\n\n### 3. GRU v3 Model (`config.gru_v3`, `config.control.use_v3`)\n\n* **New Architecture (Task 3.1):**\n * Implemented `model_gru_v3.py` with `GRU(units) -> Attention -> LayerNorm` structure.\n* **New Output Heads (Task 3.2):**\n * `dir3`: Dense(3, softmax) for ternary classification.\n * `mu`: Dense(1, linear) for return prediction.\n* **New Loss Configuration (Task 3.3):**\n * Uses `CategoricalFocalCrossentropy` for `dir3` and `Huber` for `mu`.\n * Loss weights configurable.\n* **Configurable Hyperparameters (Task 3.4):**\n * New `gru_v3` section in `config.yaml` exposes `gru_units`, `attention_units`, `learning_rate`, loss parameters (`focal_gamma`, `focal_label_smoothing`, `huber_delta`), and loss weights (`loss_weight_mu`, `loss_weight_dir3`).\n* **Model Selection (Task 3.5):**\n * Added `control.use_v3` (bool) flag to switch between GRU v2 and v3 logic within `GRUModelHandler`.\n\n### 4. Vector Scaling Calibration (`config.calibration`)\n\n* **New Calibrator (Task 4.1):**\n * Added `calibrator_vector.py` with `VectorCalibrator` class implementing vector scaling (optimizes diagonal matrix `W` and bias `b`).\n* **Method Selection (Task 4.2):**\n * Added `calibration.method` config option (`temperature` or `vector`). `TradingPipeline` routes to the appropriate calibrator.\n* **Parameter Handling (Task 4.3):**\n * `VectorCalibrator` saves/loads its parameters (`[W_diag, b]`) to `.npy` files.\n* **Logits Requirement:**\n * Vector scaling requires pre-softmax logits. Added `GRUModelHandler.predict_logits` method using an inference-only model view to retrieve these without altering the main model structure.\n\n### 5. SAC Stabilisation (`config.sac`, `config.environment`)\n\n* **Reward Scaling (Task 5.1):**\n * Environment reward is multiplied by a scaling factor.\n * Config: `environment.reward_scale` (float).\n* **State Normalization (Task 5.2):**\n * Added `utils.running_stats.MeanStdFilter`.\n * `SACTrainer` optionally normalizes environment states using this filter.\n * Config: `sac.use_state_filter` (bool).\n * Filter state is saved/loaded with agent checkpoints.\n* **Target Entropy Calculation (Task 5.3):**\n * `SACTradingAgent` automatically calculates target entropy as `-0.5 * log(4)` if `alpha_auto_tune` is true and the default `target_entropy` (`-action_dim`) is used.\n * Config: `sac.target_entropy` (float or null).\n* **Action Penalty (Task 5.4):**\n * Added quadratic penalty to the environment reward based on action magnitude.\n * Config: `environment.action_penalty_lambda` (float).\n* **Oracle Buffer Seeding (Task 5.5):**\n * `SACTrainer` can pre-populate a percentage of the replay buffer using a heuristic policy based on GRU predictions.\n * Config: `sac.oracle_seeding_pct` (float).\n* **Metadata Update (Task 5.6):**\n * `reward_scale` and `lambda` (action penalty) are now saved in `agent_metadata.json`.\n\n### 6. Metrics & Validation (`config.calibration`, `src/metrics.py`)\n\n* **Edge-Filtered Accuracy (Task 6.1):**\n * Added `metrics.edge_filtered_accuracy` function.\n* **Validation Check (Task 6.2):**\n * Added a check in `TradingPipeline` after calibration. Calculates edge-filtered accuracy on the validation set and computes the 95% CI lower bound.\n * Pipeline fails if CI lower bound < 0.60.\n* **Re-centred Sharpe Ratio (Task 6.3):**\n * Added `metrics.calculate_sharpe_ratio` function allowing custom benchmark return (defaults to 0).\n* **Backtester Reporting (Task 6.4):**\n * `Backtester` now calculates and saves edge-filtered accuracy and re-centred Sharpe ratio to the metrics file.\n\n## Configuration Summary\n\nSee the updated `config.yaml` for details on the following new/modified sections and parameters:\n\n* `data`: `vol_sampling`, `vol_window`, `vol_quantile`, `label_smoothing`\n* `gru`: `use_ternary`, `flat_sigma_multiplier`\n* `gru_v3`: (New section with architecture, training, and compilation parameters)\n* `calibration`: `method`\n* `sac`: `use_state_filter`, `target_entropy` (updated behaviour), `oracle_seeding_pct`\n* `environment`: `reward_scale`, `action_penalty_lambda`\n* `control`: `use_v3`\n\n*(Note: Some parameters under `gru` like epochs/batch_size/patience primarily apply when `control.use_v3` is false)*.\n \ No newline at end of file diff --git
