Here's mine:
​
\- VPS using Rocky Linux 4GB RAM and 2vCPUs. Approx $20-30/month cost.
​
Note: I found my VPS terminal to use 256 colours/8-bit so I must make sure any app doesn't use "true colour/24-bit" otherwise the app will crash so I must default everything to 256 colours.
​
\- byobu which is a tmux wrapper and easier to use than directly using tmux IMO. I use this so my instances don't go down when I close the VPS https://byobu.org/
​
\- process-compose to launch all of my instances (I have one instance per symbol so one symbol crashing doesn't take down multiple symbols) and all built into one's own process-compose YAML file with auto-crash restart, log rotation and more: https://github.com/F1bonacc1/process-compose
​
Note: I launch byobu and inside it run process-compose
​
\- algo programming language: OCaml (+ OxCaml)
​
\- Internally rate limit price updates to every 500ms. I don't need high frequency price updates which would unnecessarily increase CPU/memory usage for no extra benefit.
​
That's basically it. CPU and memory usage are very stable and more than enough headway to manage spikes.
