Whenever I need a dedicated VPS I always check the deals on https://lowendbox.com/

You should be able to download via flathub too. It is self contained software but you can write to a Google or Dropbox directory and let that synch the files. I’m really a fan of logseq as well.

This would be my vote honestly.

Plenty of tools like this already exist. Trading view apple stocks built in app. If you just want the data those would be far easier. If you want to self host something just to say you did it or for the challenge, you can try your hand at python, libta, and yahoo raw data. There are ways to calculate the things you are wanting and visualizing the graphs as well. It’s pretty fun and interesting!

Edit: just found this on awesome self hosted

Pika backup seems to be mentioned a lot.

This sounds like a dream for me, what I found was even better, was making a slick deals account and setting up an alert for exactly what I needed. That way I wasn’t mindlessly shopping and buying unnecessary things! Following this thread though cuz I’m interested!

Possibly Logseq fits your purposes.

Same exact setup here. Love it so far and extremely stable.

Good bot!
