 Each configuration dictionary specifies:
-- `security_type`: "CRYPTO" or "EQUITY".
 - `data_directory`: Path to the data files.
 - `datafiles`: A list of database files to process. You can comment/uncomment specific files to include/exclude them from the backtest.
 - `db_table_name`: The name of the table within the SQLite database.
 - `instruments`: A list of symbols to consider for forming trading pairs.
 - `trading_hours`: Defines the session start and end times, crucial for equity markets.
-- `price_column`: The column in the data to be used as the price (e.g., "close").
-- `min_required_points`: Minimum data points needed for statistical calculations.
-- `zero_threshold`: A small value to handle potential division by zero.
+- `stat_model_price`: The column in the data to be used as the price (e.g., "close").
 - `dis-equilibrium_open_trshld`: The threshold (in standard deviations) of the dis-equilibrium for opening a trade.
 - `dis-equilibrium_close_trshld`: The threshold (in standard deviations) of the dis-equilibrium for closing an open trade.
 - `training_minutes`: The length of the rolling window (in minutes) used to train the model (e.g., calculate cointegration, mean, and standard deviation of the dis-equilibrium).

-    "\n",
-    "1. **Interactive Configuration**: \n",
-    "   - Easy switching between CRYPTO and EQUITY configurations\n",
-    "   - Simple parameter adjustment for thresholds and training periods\n",
-    "\n",
-    "2. **Single Pair Focus**: \n",
-    "   - Instead of running multiple pairs, focuses on one pair at a time\n",
-    "   - Allows deep analysis of the relationship between two instruments\n",
-    "\n",
-    "3. **Step-by-Step Visualization**:\n",
-    "   - **Raw price data**: Individual prices, normalized comparison, and price ratios\n",
-    "   - **Training analysis**: Cointegration testing and VECM model fitting\n",
-    "   - **Dis-equilibrium visualization**: Both raw and scaled dis-equilibrium with threshold lines\n",
-    "   - **Strategy execution**: Trading signal generation and visualization\n",
-    "   - **Prediction analysis**: Actual vs predicted prices with trading signals overlaid\n",
-    "\n",
-    "4. **Rich Analytics**:\n",
-    "   - Cointegration status and VECM model details\n",
-    "   - Statistical summaries for all stages\n",
-    "   - Threshold crossing analysis\n",
-    "   - Trading signal breakdown\n",
-    "\n",
-    "5. **Interactive Experimentation**:\n",
-    "   - Easy parameter modification\n",
-    "   - Re-run capabilities for different configurations\n",
-    "   - Support for both StaticFitStrategy and SlidingFitStrategy\n",
-    "\n",
-    "### 🚀 How to Use:\n",
-    "\n",
-    "1. **Start Jupyter**:\n",
-    "   ```bash\n",
-    "   cd src/notebooks\n",
-    "   jupyter notebook pairs_trading_visualization.ipynb\n",
-    "   ```\n",
-    "\n",
-    "2. **Customize Your Analysis**:\n",
-    "   - Change `SYMBOL_A` and `SYMBOL_B` to your desired trading pair\n",
-    "   - Switch between `CRYPTO_CONFIG` and `EQT_CONFIG`\n",
-    "   - Only **StaticFitStrategy** is supported. \n",
-    "   - Adjust thresholds and parameters as needed\n",
-    "\n",
-    "3. **Run and Visualize**:\n",
-    "   - Execute cells step by step to see the analysis unfold\n",
-    "   - Rich matplotlib visualizations show relationships and signals\n",
-    "   - Comprehensive summary at the end\n",
-    "\n",
-    "The notebook provides exactly what you requested - a way to visualize the relationship between two instruments and their scaled dis-equilibrium, with all the stages of your pairs trading strategy clearly displayed and analyzed.\n"
