# Heatmap
### Introduction
The **Heatmap** is the latest innovative widget added to the OSS (Option Strategy Simulator), designed to revolutionize how traders analyze Bitcoin options. This dynamic tool provides a vibrant, intuitive visualization of trading activity across adjustable time frames, expiries, and strike prices. By representing trading activity through a color-coded heatmap, it highlights which strike prices have been most active within a selected timeframe and which expiries have been traded the most.

The vertical column on the right showcases open interest by strike, while the horizontal columns below the timeframes display activity by expiry, offering a comprehensive view of market trends at a glance. The Heatmap’s seamless integration with other OSS widgets, such as the Strategy Builder, ensures that all essential tools are accessible within a single, user-friendly dashboard. Traders can zoom in or out and adjust the map effortlessly with simple mouse interactions, tailoring their view to their unique preferences. Additionally, with the live Bitcoin price overlay, users can correlate trading activity with market movements instantly. This cutting-edge widget is part of our continuous efforts to enhance user experience, offering a powerful and unique tool to simplify and elevate options trading.
### Accessing the Heatmap
