I succeeded with CryptoCurrency Automatic Trader (C.A.T.) on headless server
I am glad I can announce that I succeeded to run my C.A.T. on a headless server.
You know that C.A.T. is a Java 8 program and that it interacts with a GUI. Servers do not have that!
I wanted to put my C.A.T. on a server for several reasons:
1. to save my computing power on my desktop/notebook
2. to save electricity to avoid to operate a dedicate computer including air condition
and add new features, like:
3. to access my C.A.T. via my phone
4. or general from any place with Internet
