Hello Desktop
Desktop
A Fresh Look. More Flexibility.
This update expands where you can trade while preserving the performance and reliability you depend on.
Cross-Platform Support
Sandwich is now available across multiple platforms, delivering stability during chaos wherever you work.
You can now trade seamlessly on:
- Windows
- macOS
- Linux
Each platform delivers the same consistent performance and unified experience.
Visual Refresh
The layout you know and trust remains unchanged, but we’ve refined the experience with:
- A refreshed color scheme
- Softer edges and smoother interface elements
- Updated typography for improved readability
The result is the same intuitive structure — now presented with a cleaner, more modern feel.
What Hasn’t Changed
While the surface has evolved, the foundation remains firmly intact:
- The same robust infrastructure
- Reliable, consistent performance
- The high-speed execution engine that powers every trade
This is an important step forward. With automation features already in development, we’re layering in even more precision and control — building a smarter, more responsive Sandwich experience.
