Its ugly and I know im doing a bad job

Its a project I do for both learning web-dev and help my stock-trading activities. Ive invested 200+ hours until now and I dont like the end result.

Im a terrible designer, not focusing on the important things, data is messed up and code quality is bad.

On the bright side, its a live and I use it from time to time.

Not sure where to take this project further
