what is delta-terminal fr?

Delta Terminal is a free, do it yourself version of the expensive data terminals that professional traders and analysts normally pay tens of thousands of dollars a year to use. Instead of a paid data vendor, it pulls together roughly 48 different live data feeds from free, public sources and displays them all in one screen, styled like a professional trading terminal. The data covers a lot more than just markets. Alongside stocks, crypto, bonds, currency exchange rates, and economic indicators, it also tracks real world information such as live aircraft and ship positions, weather, earthquakes, wildfires, satellite data, and even geopolitical events like conflicts and sanctions. There are also feeds for things like security vulnerabilities, website outage status, and news from sources like Hacker News. Under the hood, a backend built with FastAPI, a Python web framework, collects all these feeds and makes them available both as standard web requests and as a live WebSocket stream, so the display can update in real time. The screen itself is a panel based web interface built with React, showing things like maps and order flow visualizations. There is also a desktop version built with Electron that automatically starts the backend and wraps the interface as its own application, so it can be run like a normal installed program instead of through a browser. Most of the data feeds do not require an API key at all, and any that do can have their keys placed in a local configuration file that is never shared or uploaded. Since the underlying data sources are free public APIs rather than paid services, the project notes that individual feeds may occasionally break or get rate limited as those outside sources change, and the system is designed to skip a broken feed rather than fail entirely. The project is released under the MIT license.
