for daytrading / system running 24/7, with catalyst:
which is good hardware and operating system?
raspberry Pi 3B+ with raspian strech (32 Bit) - or Raspberry Pi 3B + a 64 Bit Linux
-> small energy consumption and space, maybe good for running the ready system.
-> maybe not enough power/RAM for developing (how much RAM does Jupyter notebook use?), so developing could be done on an existing office PC.
A separate small office PC + a Linux distribution
