Please, "The design is very harsh on the eyes." is an understatement, I really had a hard time navigating the pages and reading the text.

Just out of curiosity, did you code the pages by hand, not using any frontend/style framework? It sure does look like it.

I don't mean to be mean or just point and laugh at someone that is starting out, but I'll be blunt on what I found

I have no idea of what I'm looking at:

- There is little to no actionable information from the home page.

- The /algorithms page reports almost the same data as the homepage, still barely comprehensible. There I see the one and only suggestion that this may be some kind of paid service.

- Documentation:
There is an empty square for some reason. The big empty squares overflow on the footer.

- API Code in the same font as the text without highlighting? No actual information of the format of passed/returned data?

- The user guide leaves me with even more questions than what I had before entering it.

- The /available_assets page is flat out useless, No asset has a type or exchange, why have that table? The pagination is aligned to the left, and I just have a regurgitation of some 20.000 symbols and names. I had to click the search button to see that the weird box on the top was a text field and not another UI glitch.

- What even is the news page? Some kind of link aggregator of external news? Isn't algorithmic trading meant to have as little human intervention in the loop as possible? Why does it even exist?

- The about us page has pretty much the same information present in the homepage, but with your face on it, still i know little about the website, or you for that matter.

- At the time of writing this, the CSS of register form is completely broken, and I mean completely. If you're posting to HN at least have something usable.
Do you want me to give out all of my personally identifiable data, including a scan of my documents, to an entity that is so incredibly shady, on a website that is barely readable and has "terms of use created using Termly's Terms and Conditions Generator."? That's not going to happen.
This saddens me a little since I won't be able to peek at the tools and pages once you're logged in.

- The footer and other elements changes size, shape and position in almost all the pages, do you just have HTML templates for the pages with copy-pasted elements?

- The homepage has 3 random canvas elements that are going to suck up all the GPU you can give them, I assume to look cool.

Please, let's not talk about mobile.

Again, I don't mean to be harsh or unnecessarily mean, but this is a bad execution. I did one Web project together with 2 other people that never touched frontend code before for a University project, working MAX 8 h/week for a month and I'm sorry to say that we did a better job at building a usable website.

I know that a pretty website is not the goal of this, and probably there's much more under the hood / in the reserved areas that I could not access but, especially when we're talking about money and investments, you simply cannot afford to look this bad.

Seeing as you're a one-man team, I would suggest working a little more on the presentation, maybe find someone willing to do it for you, or at least help you out.

There's much much more I'd like to ask, but for this comment I'm just going to focus on what I can visually see.
